POST 1 / ORIGINAL POSTEROriginal post

Hey guys just want to know how many of you have had IMS Bearing failure and how many miles were on the car when it happened. My car has is a 01 c4 with 12350.. I have the engine out now and we are installing the new bearing by ln engineering

POST 3Original post

They seem to happen at all different mileages. It seems like many of the cars were low mileage cars not driven too often. Hard to say with out making a career of research. Best of luck to you.

POST 4Original post

Best explaination I've heard. Cars not driven much. Condensation forms in the crankcase. Water naturally goes to the bottom, which is were the IMS bearing is located. The sealed bearing has a tendency to be wash out with engine oil. In time water makes it way into the bearing. In time the bearing fails. Remember in time ALL bearings fail. This is just a theory I've heard, but makes sense to me. So run you engine regularly long enough to evaporate interal condensation. Change oil annually or 7500mi which ever comes first. I wonder how many oil changes your 12,000mi engine has had?

POST 5Original post

92,000 miles here, and going strong on my original engine. No issues.

POST 7 / ORIGINAL POSTEROriginal post

hey click click yearly documented oil changes on this car. just not enough miles on it. new ims bearing arrived going to install tomorrow. will let everyone know the outcome. motor cleaned up all visable metal removed. lets hope for the best.. thanks to ln engineering for all there help.

POST 9 / ORIGINAL POSTEROriginal post

This ims is a real problem and its time we get all the names of people and start a class action suit. i'm willing to do the leg work to get this going so anyone that has had this problem pm me your info so you dont loose rep points to.

POST 10Original post

I had mine IMS failure 2 months ago....and the car is still at my local Porsche shop for repair.... I had my failure at 60.000 kilometers - so agree on the fact that it is often engines with low mileage.... I have discussed the matter Porsche HQ in Germany and Porsche Denmark, with no major result

POST 11 / ORIGINAL POSTEROriginal post

ok spent the weekend cleaning the motor and installing the new ims bearing. engine is ready to go back in car on tuesday. if anyone is attempting to do this themselves it wasnt as hard as the instructions made it out to be. the hardest part was getting the old bearing out and cleaning out all the metal peices. lets keep outr fingers crossed. if anyone is on long island and needs the kakka pullers let me know and you can borrow them since they were a few hundred dollars....

POST 12Original post

I'm a little confused - Wouldn't the current IMS and RMS that Porsche makes be up to quality standards, by this time. Therefore, why not just get the latest Porsche part rather than go aftermarket. After all they changed engines in 2005 (I think?)

POST 13Original post

Was the bearing in several pieces or heavily worn? Did you lock the cams in place and remove the chain tensioners? James Greer

POST 14 / ORIGINAL POSTEROriginal post

ln engineering has the only parts available for this. porsche does not have an assembly that even comes close to this quality.

POST 15 / ORIGINAL POSTEROriginal post

My bearing was gone. i dropped the pan cleaned everthing removed the oil pump pickup, and cleaned everything out. i pulled the cam plugs to make sure the timing did not jump and everything was dead on. i did bring everything to top dead center and use a 1/8 punch to lock in place.. since the timing marks were right on what i did was go about 10 degrees past top dead center and then brought the pulley back. to dead center. this gave enough slack to bring the shaft to the center of the opening so i didn't have to remove the tensioners. Im hoping everything is ok because it was running fine when i shut it down and there was plenty of oil pressure. I removered the pan and found some pieces of metal but it looks like most of it stayed in the intermediate shaft. i removed and disassembled the oil pump and found no metal filings in there. there was some filings in the filter. i'm starting to put the engine back in the car tonight and hopefully have it up and running later in the week.

POST 19Original post

I bought my 99 C2 six months ago and I am starting to regret it, after all the rattle chasing, suspension issues, electrical issues and IMS worries its just not worth keeping the car. It’s a shame the car is so beautiful from the outside but a nightmare every time you turn the engine on. I am starting to go on the 997 boards to see there issues as I might make the step up.

POST 20Original post

Remember that IMS problems are still an issue in the 997's up until the 997.2 was introduced in 2009 with the new engine. And in M97/97 engines produced starting in 2006 the IMS bearing can't be replaced as it was changed to be bigger than the opening in the cases. If you are buying a 10+ year old car you have to expect some issues, no matter what the make. Drive the car and enjoy it. The cost differential between a 99 and a 997 is more than the cost of an engine, and they still blow up once in a while. Remember that the posts you see on the forums are from those of us who have had problems (I had an intermix) and there are more cars out there that have not had problems than there are ones that have had problems. And the next time the trans is out do the LN upgrade and then don't worry.

POST 21Original post

I have a 1999 996 and have had no issues with the RMS or IMS. My car has 60K. Check the other forums and you will see problems exsist in every model. I plan to do the IMS bearing upgrade soon as it appears that is a wear item and should be replaced. Enjoy your car and don't be afraid to drive it.

POST 22Original post

My RMS started leaking at 120k miles on my 99 C2 Tip that sees quite a bit of use on the track. Can't complain much. While the engine and tranny were out, we put in the LNE retrofit, changed the RMS, new oil separator, water hoses, o rings, and anything else we could see going any time soon. All for about 4k. I'm looking to put another 100k miles on it as quickly as I can. Drive it hard and enjoy it as much as you can We drive it about 20k miles/year.

POST 23Original post

ok engine and tranny back in car, just finishing up connecting all the harnesses and she is ready to start.should be running in the next few hours..

POST 24Original post

Wow! Were you able to take photos and document the process? Way to go...

POST 25Original post

job complete 75 miles on new bearing and engine ,oil pressure a ok. No noises or vibrations in car on accel or decel. Hopefully this is a save. Just wanted to thank LN ENGINEERING for there help and everyones support on here.

POST 26Original post

Congratulations!!! I think you did the right thing. Hopefully you will have 100,000+ of enjoyment now.

POST 27Original post

Well maybe this overly simplistic stat shows how common (or uncommon) an IMS failure is. As of today, this thread has been viewed 1226 times (granted, not all 1226 views were different users) and 2 people have reported IMS failures in this thread. Not that it's a scientific measurement or anything, but come to think of it, I've never heard a scientific measurement of the rate of IMS failures.

POST 28Original post

Your right your post holds no scientific value what so ever but it damn makes me feel a bit better!!!

POST 29Original post

One of the pcar rags, GTPorsche, 911&Porsche, Excellence or Total Porsche had an article with an unofficial stat with IMS failure at less than 5% recently.

POST 30Original post

Mine went on me (2005 997) 3 weeks ago. Sent it to the dealer, PNA came back with a reman engine that was installed last week at no charge to me. I had to do a little coercion and chest thumping, but they came through. Dealer told me he had seen 10-12 cars over the last few years and PNA did not always pick up the bill.

POST 33Original post

Things like this is why I personally wouldn't want one without a warranty. My warranty ended last May and as I couldn't get what I wanted I replaced my boxster with something non-porsche. I do miss a porsche and will probably get another but it will have warranty.

Quotes source post: 3491474

Quote: Might have touched a nerve! First off with reference to the warranty comment- in the two years I had my porsche under warranty it was in the shop more than the 2 japanese vehicals I had in the 8 year period period before getting it. When the warranty period ended this was not a vehical I wanted to keep. Having said this I love driving a porsche......bar none it has been the best driving experience of any vehical to date. Driving experience superb but confidence re reliability less so.But, unless it was a 2009 or later I would not buy it and would not want it out of warranty. Simply personal preference. I mentioned to my lady friend today I'd like to get another. I researched the h@ll out of porsche products and I have to question how they could produce vehicals at this price point for so many years with a known problem and not fix it till 2009.....the ims. Anyway, based on two years ownership of a cpo car and contemplating spending the better part of 100 big ones on another one I will raise whatever point I choose politely. If you feel I need more posts under my belt before doing so feel free to ban me. Respectfully Dbw

Quotes source post: 3491564

Quote: Do some research.. there is lots of material on that " secret problem", frankly it's not that big of a deal but if you buy a 2009 or later.. you should get an extended warranty... these cars are expensive... no matter what goes wrong and why it goes wrong (some of it will be driver related for sure). This is super-car territory with prices for parts and labor to match and there is very little out there that matches the performance in a car that can be used as a daily driver.

POST 37Original post

Quotes source post: 3491474

Quote: Which one? "rketekt" or "dbw"? Considering that rketekt used his first (and so far, only) post to bring up a 2 year IMS thread in the WRONG forum, I whole heartedly recommend that his post be deleted. As for dbw's assertion that he wouldn't own one of these without a warranty, I can only offer my experience. I bought a '99 C4 in April 2010 with 14K on the odometer. In the 2 years/15K miles since, I have had 3 oil changes, one brake fluid flush, replaced one oxygen sensor and replaced a set of tires. Only one of those could be considered a warranty item, so I would have lost money on an extended warranty.

POST 38Original post

I just had the bearing replaced in my 2005 boxter as a preventative measure. I have 59,000 miles on the engine. When the bearing was removed it looked like a little bit of wear. I had the main seal and clutch also done at the same time by Musante MotorSports in South Windsor Connecticut. They specialize in Porsche upgrades and regular service.

POST 39Original post

I feel like a broken record. It is a KNOWN problem (on about 10% of the cars). It is a SERVICE item. Get an LN bearing, drive for 40k+ miles, monitor and get it changed. I have had my P car with zero (knock wood) issues. Even if it does have some, it is a near super car that retailed for over a $100k, expect it to cost more than your honda.

POST 41Original post

Quotes source post: 3492126

Quote: If it is a Service item, it should happen on ALL cars and there should be estimate at what age/ mileage that is likely to happen, like you would see that item pop up in the 30k miles / 60k miles / 90k miles Service Book for the Owner. So I am not sure that this is a Service Item in the traditional sense of the word. I am not buying that. Having said that, this is all gone and bye-bye as we no longer see that issue on new cars with basically the same engine / lay-out and with even more power.

POST 42Original post

Read the recent reports in Excellence etc. All the mags have narrowed it down to about 10% after their research. Is it accurate, who knows, is it close probably. It is a service because it is a moving part that wears, and sometimes prematurely like any other bearing can. The estimate on LN site is 50k miles, I beleive. http://www.lnengineering.com/ims.html This is way beyond getting old.

POST 43Original post

Quotes source post: 3492184

Quote: What's getting old is that any time the IMS bearing topic appears to die down in the forums, someone always manages to stir it up again with no new information to offer. What's getting old is people spouting off IMS failure rates as fact with no proof and no way to actually get proof. Very few people deny that some cars have experienced IMS bearing failure. But when trying to objectively determine the extent of the problem, it sure would be nice to have some actual facts rather than mass hysteria. Let's ballpark this: say there were 150,000 cars produced, so the 10% failure rate you mentioned would equal 15,000 cars. At that rate, shouldn't the streets be lined with 996 carcasses?
