I use a Goodyear place because i can walk under the car and check for leaks look at tire thread, etc, and also they don�t mind that I take my own oil and filter.

Suspected cause
Idling, let alone driving for any amount of time without oil pressure was a mistake and likely an expensive one, really too bad.

Today wasn�t a good day. One problem after another. Simple procedure. I want to cut to the chase and get to the point.
Doing a simple oil change. Started out by finding out I purchased the wrong part from an unmade parts store chain. First set of problems started when I removed my oil filter and a part was lodged in the top of the existing filter. I figure no problem. Pull it out push it in place and proceed. Well problem number two after installing if oil filter and filling with oil. Start the car. Lots of ticking no oil pressure. I figure a short spin and it should come to life. After a quarter mile or so. No change. I get it home. First thing I do is take the oil filter out. That part that came out still had me
concerned I compare filter sizes. The new one is to big. There part number. I go back with the original filter and there filter. They agree. Not a match. Look at another brand and found a match. I get home and with the feeling things will go smooth. I push the part that came out with the filter up in place and install the new filter. I add the oil back into the car. Go for test drive number two. Same noise and a flatlined oil pressure gauge. I drive a little further hoping when it heats up all will be good. Car stalls. This is when I became fear stricken. I get it started and get it home. Going to make the turn into my driveway car stalls. Open engine bay and remove oil cover. Heavy smoke. I have no idea what is going on. I will attach an image of this part. I�m still not sure what it is. It has a spring so I assume it�s a thermostat. I tried starting the car. It won�t start. I pick up for the night. I am concerned. I�ve got a problem. I don�t know what it is. I�ve done a dozen or ore oil changes. The car was running tip top before the oil change. Can anyone help me figure out what is going on?
That part is the oil filter by-pass valve, it should be attached to the "bottom" of the oil filter canister/oil filter. If you attached it to the "top" of the oil filter you would have blocked the oil flow hence your flat lined oil pressure and lifter noise.
Sorry to say, but driving the car or running the engine long enough to stall/seize, probably has catastrophically damaged the bearings, your engine is most likely "Done".
The engine cannot be trusted until the extent of the bearing damage can be visually assessed. (meaning engine disassembly for inspection /assessment).
Wow...and Wow...and WOW!! You turned an oil change/filter change into a literal nightmare. Actually, you have no idea what your are doing, and in the process probably and seriously blew your engine. For it to "flatline" on oil pressure and completely "stall" means your engine seized up and the bearings (or whatever) are ruined. You turned an "oil/filter change" into a +$20K repair. Sorry for that. Good luck.
New user, first post. I hope this is a belated April Fools post, otherwise, one destroyed engine due to someone attempting an oil change and not knowing what they are doing. Either way, sad, very sad. M96 gets enough of a bad rap for issues - it doesn't need help from idiot humans.
DB knows a lot about these cars, doesn't know a lot about not coming across as an (Insert adjective here)
Unfortunately for the OP, not likely to be a good outcome here. Idling, let alone driving for any amount of time without oil pressure was a mistake and likely an expensive one, really too bad.
Do whatever Skip (Porschetech) says and hope.
Well I swapped everything around. Added new oil and it runs like a top. Does that mean it’s still catastrophic?
I don’t doubt that I may have caused some premature wear or some issue. I do know that it runs and sounds fine.
That’s what I can tell you today.
Im no being a smart *** either because I went to bed one nervous person. Just to hear it run and sound good was
enough for a smile.
The rest remains to be seen.
Glad to hear that, and I hope it continues to run well. You were just coming here for some help in a bad spot, and I hope some of the comments here don�t deter you from sticking around and joining the community. We all make mistakes, and hopefully yours turns out to be just a scare.
If it runs... I would drop sump NOW and get any debris that may have been generated running it without pressure out of the engine before it further contaminates the oil system.
WAY too soon to be smiling !! If you had done that to my engine, ..........
Do like Zbomb said, drop the sump NOW and check for debris, run the engine for a hour and check oil pressure hot idling, check oil filter for debris, drop sump and check for debris, get an oil sample to send to LAB.
If all that checks out good, change oil and filter again, and after 50 hours if all is still well, THEN Start Smiling...
I have been lurking here for many years. I see what goes on and what’s said. How people behave. It’s not worth posting ever. I did a search but could not come
up with anyone. Yes it was a dumb mistake. I’ll admit it right up front. I also knew I would get a couple of guys coming at me with there list to be cruel. It happens a lot here. As far as joining. I’m done. I hope my car continues to run well but if it doesn’t I will fix it one way or another. One thing for sure is it won’t be discussed here. 95% or more
of the people here are great human beings who really want to help people not hurt them or kick them when they are down. Computers and smart phones have given people with mental illness the ability to be very vocal. Much less than they would be in public. Some would still be. The jails are full of them.
thank you for helping me correct my stupid mistake. I still can’t believe it happened. I’ve changed my oil before. The part must have stayed in place in the filter canister. This time it came out with the filter and I made the wrong choice. Yesterday sucked. Today is a new day. I’m not looking back. I live one day at a time. Those with negative things to say are not welcome in my day today.
Ill be around!
Happy motoring......
Not trying to add insult to injury. Looks like the gang here on RL has already given you the pill that is hard to swallow. When I find an unusual/odd part fall out when repairing something, I don't rush to reinstall it until I've verified the exact location with either the shop manual or parts diagram. I've also learned to take a deep breath before making a mountain out of a molehill. It's one thing to shoot yourself in the foot, but you don't want to shoot both feet or you won't stand!
Now regarding the oil filter canister, I've moved to the LN Engineering spin-on oil filter adapter. This saves a lot of time and less prone to error, but I understand if you want to stick with the factory canister with the by-pass value.
Moving forward, I would definitely listen to PorscheTech3's advice. If anyone on this forum knows what to do in this case, it's him. Listen to his advice!
I actually do feel sorry for the problems OP brought upon himself, but it is also clear, and realistic, that he does not know what he is doing. And what is this about wrong part from an un"named" auto parts store? This is a clear example of not knowing what to do and how to do it. I spelled it out pretty clear and the very first clue was no oil pressure, then taking the car for a spin. Who does that? Yes, I feel sorry he got himself into a potentially big problem with such a simple procedure. Now he says it is running perfectly. Huh.
Dodger,
Hang in there buddy. Don't exit the forum because of a few folks can't control their impulse reactions. Vast majority want to help. I've had my 996 for 19 years and still havent develop mechanical skills, no matter how much I read and try. I for one appreciate that you asked the question. We all make mistakes. I have a laundry list of them. Some of you guys owe Dodger an apology. He is just looking for answers like all of us. Finger crossed that all is ok.
If you need advice on your Porsche : this is the place
If you need to be tucked into bed with a nighttime story about your Porsche : this is not the place
Lots of helpfull folks here, the fact is some car events are beyond help and are just simply sad and hard to swallow.
Lurkers :::
Yeah... I mean the guy is facing a $20k mistake and asked for some advice and the first reaction by some is to start bashing him. I don�t care how much knowledge or experience you have... it�s just not a good look.

Damn, I gotta tell my wife she can't read to me any Porsche publications anymore before bed...😁
****, I guess I'm out.
I thought, like at some point, after you paid your dues, put up with some peoples bull **** and persevered, maybe helped a person or 2 out... Nighttime stories were part of the deal.
No, if your wifie is reading you bedtime Porsche stories, and you like it, cherish the moment..
My first ex-wife (mother of my three children) just passed away three days ago,(cancer) THAT is what is tragic, not some goofy mistake on an engine, even it is a 20k mistake, it can be fixed.
Yea,, some threads are more for "nitetime" reading and "feel good stories" , but if if starts off with "I need help, I may have F**ked up", it usually gonna be one of those "nitemare threads"..
I once drove a bmw 535 for about 10 miles with no OP. I was pissed at it because it would not develop pressure sometimes after it sat. It didn't appear to suffer any damage
It was already suggested here but a really good investment is the LN Spin on oil filter adapter. Can't go wrong with that. Also, if not doing that, then it is highly recommended that you buy a new oil filter canister. Comes from Porsche and includes a new bypass valve (in the bottom of the canister) and oil filter. The bypass valve is spring loaded and tends to become weak with age/mileage/heat. Last I heard you can get it for less than $30.
Dodger13, Sorry for your event. It's no fun when things don't work right. Good to hear that it's not dead. Don't take any offense from anyone here. Everyone wants these cars to work as well as possible, truly. And we the caretakers get in the way of that happening. Please do take the advice about checking out the sump and getting the UOA. Sleep comes easier knowing the condition of your bearings... And please keep posting. If nothing else, post a picture on "what did you do to your 996 today" and tell us where you drove it! That one thread has just about every event that could happen to these cars in it with much less of the detail back and forth. This site is amazingly valuable. Or, jump in further and post pictures of your dropped sump here. Everyone will be happy to tell you what's going on. If there is something bad, you'll get a bunch of different POV's on it. Then you get to decide which way to go... Regardless what you do, Good luck, drive fun!
I ran my engine with no oil pressure for a trip around the block, what do you guys think? If you have realistic or what I deem to be cruel comments, please do not post. I think these engines benefit from running now and then with no oil pressure and will be fine.
Oil pressure sending unit could be faulty. And, could be something very serious with the oil pump or a blockage in the return.
That's crazy... don't even think like that!
I pity the next owner. Driving about a mile (1/4 out, 1/4 back) twice, having the engine die twice due to what had to be excessive heat, smoke pouring out - the main and rod bearings took a serious hit. Spun bearings and bore scoring are almost guaranteed for this engine.
If you don't think so, take the car out for an extended 2nd or 3rd gear run at 6K RPMs for 15 minutes. Ignore the sounds that you will likely hear, be prepared for a ventilated block...
Yep, pity the next owner when the current one ditches the car somewhere.
Best of luck!
This is why I don�t even attempt to do simple things like this on my own... much less tell internet �experts� about it haha! I know I�m useless mechanically and I don�t need people on here to shame me
whatever happens, it�s just a car
I'm still struggling to understand how it is actually possible to do what the OP is saying. If that bypass valve was put on the "top" of the filter (the end of the filter that contacts the engine), how he could even have installed the filter and housing? If the opening in the top of the filter was blocked, the filter should not have been able to push up on onto the pipe coming out of the engine and you shouldn't even be able to screw home the filter housing....it'd take some significant force to compress the filter axially, I would think. If he pushed it into the "bottom" of the filter (the part that faces the pavement), it wouldn't block anything....oil would still pass through the filter as intended.
OP, did you put the bypass valve in End A or End B of the filter in the orientation of the housing in the image below? If the piece came loose from the housing sometime after your last successful oil change, you should have FOUND the piece in the end of the old filter that was in the bottom of the housing (the side facing the pavement).
Yea, I feel ya... be careful with those dating sites. You never know what you'll get in the end.
Seriously... wish you the best. Hey... how about posting a picture of your car! Let's see it!
Porschetech3,
I am sorry for your loss. No matter how you feel about your ex, that is a terrible tragedy for your children. You definitely put car problems into perspective.
definately I�m a turbine and large engine mechanic at a power plant.
think of your engine. It takes awhile to warm up the first thing is the pistons and rings as they are closest to the heat. The crank is a cold area and can spin on the existing oil for quite some time before actually damage happens. Can you get excessive wear for sure. I bet the pistons started to heat up without the oil and started to sieze or get tight in the bores so it stalled.
luckily the owner freed it back up and it�s running again. It will probably continue to run but I�m sure the ring seal ain�t so so good but you�d be surprised how long engines can run without oil. Remember the old duralube commercials.
ps it�s one thing if your engines already at full temp and you start starving it at 5000rpm at those temps tolerances get tight quick
As noted while it may not be catastrophic (now), issues in the long or short term are imminent. Given the nature of the M96 cylinder walls, a lack of lubrication and excessive heat does not bode well, much less all other components that require lubrication. It may run for now, but I wouldn't put my money on that lasting very long. I'd follow Porschetech's advice and disassemble to assess everything, or drive on the assumption that it will need a rebuild. If that seems like too much, good luck selling it while being honest with a potential buyer about this event thinking you'll get more than the cost of a roller. It sucks to hear, but we all make mistakes at the end of the day, what makes us who we are is how we manage those mistakes.
Unfortunately this one we will never know the outcome since OP no longer cares to engage due to the non-constructive comments. I don't blame them.
In the 996 forum on RL? Shocking! I only lurk here these days, and this thread is a reminder why. Compare this to the 957 Cayenne subforum (or, any other subforum here, including the more exclusive models), where you get genuine help and conversation without the fragile egos pounding away at keyboards.
It's really a shame, as the wealth of technical knowledge and generally great people are often overshadowed by the few who want this to be an echo chamber or some sort of exclusive club.
I guess, speaking for myself, being a guy way down on the experience food chain, I'd say find someone to look at it and see what if any damage is done. If you haven't already, pick up a copy of the Bentley book and the 101 projects for 996 book. I need pictures to help refer to what I'm doing, usually reading a bit and sometimes modifying whats in the books from what I've read here. Hopefully, the damage was minimal, but stopping now and having someone look at it may prevent further harm.
I'm an amateur and stories like this scare the ever-loving sh*t out of me. I appreciate OP posting this as a cautionary tale to take things a little slower, even when doing jobs I've done before. I had no idea the bypass valve could fall out of the oil filter housing.
LN spin on filter adapter is honestly worth every penny. At worse you can double gasket, but those mistakes are usually left for the oil change guys at Jiffy Lube.
I have popped out the by-pass valve just to look at it. I suppose if the filter was extremely tight on that plastic piece that holds the by-pass valve, it could pop off. Once that happens, it is possible somebody may not know how to re-install it. This thread may save someone down the road when they find themselves experiencing the same problem while changing the oil, but then knowing what to do to avoid the issue that happened to the OP.
Honestly, though, there is "amateur" and there is "functionally illiterate". The OP's experience indicates that does not understand something as basic as what an oil filter does...else why would he willingly block off the end going into the engine, let alone drive the car with no oil pressure after just filling the oil. It also shows that he had no awareness of how the parts came off the car....if he did, he would have found the valve stuck to the bottom of the filter when he took it out of the cartridge (if it broke off between his last successful change and this one). I don't think there was a time when i didn't have to pull the filter off the pipe stub that comes out of the engine...he ignored that, too. He said the new filter he put in was too big....he didn't compare the parts or catch that. Too big how? Wide? Tall? Lastly, the cartridge must have gone on really hard and been very different than all the other times he supposedly did it whether it was too tall or not. So many warning signs here....that's not "amateur", that's a total lack of situational awareness and basic understanding. Amateur is not having a great deal of experience, but getting the gist of what needs to be done and why....you might need some guidance, some reference materials (and you know it!) but can patiently work through it with a basic understanding of the tools and concepts to start (or take the time to learn it first before jumping into the job). At least, that's what I think...and I'm definitely an amateur. I don't think the OP was up to the task of maintaining his own vehicle.
I guess everyone has to start somewhere. No doubt there's less to mess up with a spin on filter, but probably wasn't aware that it existed for this car. Maybe we've been trolled, I don't know.
Profoundly ignorant comments by the self important scolds on this thread should not be taken to heart Dodger . It's hard to believe that adults can still behave like they are on the elementary school playground, particularly on a forum that is supposed to celebrate a common interest we all have, our love for Porsches.
Any damage is done, so just drive it and hope for the best.
I've done it... **** happens when you're working on...anything and no amount of knowledge can fix not paying attention and that whole not paying attention thing can definitely initiate the **** happens moments.
If you work on cars, you will make mistakes... even ones you know not to make.
Try not to make the same one twice.
ETA... Skip - missed your post on your loss, I'm sorry. My heart goes out to you and your kids brother...
Yes I know a lot of people here work on their cars. If you don�t want to get your hands dirty and then be told at your local part store that their used oil tank is full. Take your car to a small shop. I use a Goodyear place because i can walk under the car and check for leaks look at tire thread, etc, and also they don�t mind that I take my own oil and filter. Since I watch I make certain than most oil has drain out. I look at the canister and take the old oil filter home for deconstruction, this month price $16.99. Most places don�t mind because I go during the week when they are slow and they normally don�t carry my oil and filter.
Ignorant is exactly the word describing your post. The root of the word is to ignore, and that is what you are suggesting, to drive and hope for the best. That I itself is ignorance. You are correct in the assumption that hope and ignorance are close friends.
Should the question not be �Why would a premier, elite, world-renown manufacturer of high/performance cars design such a stupid contraption for an oil filter housing?�
What Dodger13 (OP) did could have (probably already has) happened many times in the hands of many �quick lube� techs. Who knows, maybe the guys who designed the failing IMS bearing also designed the filter housing. 😂😂
It was mostly meant as a joke. I'm not afraid to say that I've made mistakes over the years, including a double gasket, on a customers car no less. We're human after all.
Ha! Valid point. However I didn't expect anything to be cheap when buying a Porsche.
This is a source reference. Confirm exact model applicability in the original material.
