In summary, it helps to look at it as buying a $10,000 to $15,000 ACV used car in which your first repair could have a $20,000 repair bill.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

After hearing sounds I did not like coming from my 2004 996 c4s and having the now famous smoked left tail pipe, I took the car to my Indi he carried out a borescope test to find heavy scoring in cylinder 6 and slight scoring in cylinder 5. Yippee
You had the tapping noise before this, did you get that checked out - was this a progression and worsening of that - seems likely..
Hopefully not unfixable

Yeah I brought the car 18 months ago the last owner had the car from new. The main services were carried out by a main dealer and the interim services at Ray Nothway Porsche(a reputable company in the uk).
The car was last serviced at Porsche at 83k. I brought the car at 89k. I have travelled in 7k in the car in total. I noticed a slight intermittent tapping noise. The car was serviced at 93k the mechanic expressed some concern about the noise but said it seemed to have stopped since the oil service but it wasn't long before it was back. I drove the car for another 1500 miles but it was getting worse so I decided to take it in before any more damage was done.
My mistake buying privately with no checks it won't happen again.
Looks like I will paying for an engine rebuild at Ray Northway Porsche.
Yeah the noise has got much worse. Probably going to reline it and look to sell her on in the summer. It's been an expensive experience my 18 months of ownership lol
Yeah the noise just got progressively worse. I don't drive the car much but when I do I generally drive it quite hard. I had my doubts just didn't want to face up to the inevitable. I am told it can be repaired

Maybe related to your cold climate in the UK? Apparently its a very common MOF that will eventually cause CEF. Sorry for your loss.
The 996 should come with a warning label explaining this.
Krazy - I hope for your sake that you are a teenager(who took a lot of pics of his uncle's C4S) posting here with delusions of grandeur, otherwise your posts are very pathetic.
If you are indeed a grown man continually posting the petty drivel that you normally post here, I can't help but feel very sorry for you...either way, get a life bro...
P.S. - I'm assuming you're a man because even a b*ich wouldn't be this vindictive...
I have never seen a bigger group of whiners who get so offended by facts. Some just cant handle the truth. I guess its kind of expected to have two groups in complete opposition here. The real men DIY'ers who don't get offended and accept the shortcomings of the 996, then there's the pansy cant touch a wrench snob crowd that worship at the Porsche alter of infallibility.
I'm glad to see more are speaking out about their opinions.
I don't think anyone on here is offended by facts when the facts are presented in a constructive way. What you present is not constructive, it is intentionally abrasive. Those of us who have been around for a while understand your game, but what you're doing really is a disservice to new 996 owners.
You are deliberately obtuse. Claiming that people here are offended by the facts as YOU present them is akin to claiming that someone hates the New York Times because their paperboy throws a rock through the front window and takes a dump on the front porch every morning. The message is fine; the messenger is the problem.
I propose the following solution for unwanted messengers:
I think it just depends on your luck.
Had mine almost seven years and my only major service has been the AOS, cats, and an alternator.
I did proactively replace the IMS and clutch when I was on an extended vacation. But as a daily driver and occasional track rat my car has performed admirably. I couldn't ask for better considering how much I beat up on it. I'm at around 158k miles on the odometer now.
hey DreamCarrera
- i'm all for degrading RL members when someones blowing BS but check your facts because KK is correct.
i've heard from several skilled mechanics over the years, with much more porsche knowledge than you'll ever have, that indeed cold temperatures contribute to these 996 engine issues. i believe it is written in a porsche factory bulletin too.
Facts are facts, and an hypothesis is an hypothesis. Not all of the "experts" - yes even those with more Porsche knowledge than I will ever have - believe the cold temp theory as it pertains to cylinder scoring.
Also, I think it was pretty clear that my comments to KK were not only about this issue but also about his incessant BS posts about CEL, MOF, etc...
Thats an opportunity. Cylinder failures are the best failure to have, seldom do we see extensive collateral damage, and often no core components that you should be reusing are damaged.
I'll take a cylinder failure any day.
I like the fuel cell. I believe it was manufactured by Coca-Cola racing. If he needs fuel while pitting, the crew can just unscrew the cell and replace it with a full one. And instead of an airbag or self-tensioning belts, it uses the back of the car in front - and the driver's face - for supplemental restraint.
Genius.
totally. I don't have much of that when it's come to this car.
1st 2 days owning it - car won't start, new battery dead. replace alternator voltage regulator.
1st week, after fixing voltage regulator, won't start when hot. probably cps, or regeneration valve, both are being replaced during my build
same week, passenger window regulator goes kaput.
same week, I start seeing big blue clouds of smoke on start up....this is when I notice black lhs tailpipe
same week...highbeam switch goes out.
a couple weeks later, I smell coolant, replace heater core in dash as its leaking.
park the car at the end of summer, pull motor, cyl 4 & 6 scored!
I'm hoping Im due for some change in luck.
Bro these are not new cars and failure are part of the gamble of buying one. Granted, 10% of low mileage newer ones also self destructed but were under warranty.
The biggest complaint buyers of the 996/M96 have is the expense(s) of repair in relation to the cars value. In summary, it helps to look at it as buying a $10,000 to $15,000 ACV used car in which your first repair could have a $20,000 repair bill. Its just hard to face that fact for some.
Yeah, we actually like the cars we own. What a bunch of idiots. Only mind-numb robots could actually prefer to think more about enjoying the vehicles and less about hand-wringing pessimism.
I can't speak for everyone else, but I'm so damn ashamed.
Say, KK, as a former 996 owner, can you tell the forum about all of the catastrophic engine failures you suffered during your time with the car? I'm sure that everyone will more fully understand your point of view once you share the number of times you were left stranded on the side of the road with oil streaming from a freshly-broken engine block...some Rennlist folks think you're full of steaming sh*t, but I alone recognize the grief resulting from a catastrophic M96 engine failure. So, please, share with the group. It can only make you feel better to share your tales of woe and horror.
I've already spent the money needed to fix the car, now spending a lot of my free time to put it all together. I'm still not "okay" with any of this. I don't think I'll ever be.
maybe that's my wife speaking.
well....in their defence, I'm sure there's a lot more people enjoying their Porsche than folks like me rebuilding them. I try not to be a Debbie downer about these things, but I certainly won't sugar coat my pcar ownership experience to date. it's been an expensive trip.
AWDGuy, you're posting your own experience. That's cool - that's what the forum is for. KK is just spouting the same crap, with no personal experience backing it up. Uncool.
Sorry to hear you have been having similar issues to me. I did not go into the car thinking it would be cheap to run probably like yourself. I wish I had more information on the cars issues before I brought it. I certainly didn't expect to rebuild an engine. Hopefully once you have had all the work done you will have a car you can enjoy.
Why does everyone have to put Brand XYZ up on a golden alter.
Porsche, BMW, Viper, Vette what-ever.
"It'll never break my car is bullet proof", or there is the doom and gloom people "she's going to blow everytime I turn the key".
It's simply a used car.
Yes, I love my 12 year old used car C4S. that's all it is, a used car with 100K+ miles on it.
you want to play, you're going to pay.
the rest is parts and labor.
stop your whining people.
Most every Porsche street car has a certain time in its life when the engine cost more than the car.
Back when I started with Porsche engines this was true of the 356, 912, and 914. Only in the last few years have 912s and 914s become valuable enough to cost more than their engines do. The 356 is a bit different, today.
The same holds true for 911s, especially the era of 2.7 through Carrera, as those engines cost more than the cars were worth for many years, too.
Today I still build those engines, and they cost more to build than a 996 engine, but the cars are finally worth something.
This is the way it is, and the way it will always be..
The problem is, the 996 became too cheap, too quick... Just like every other European vehicle of its era. The engine costs what it should, the car is too cheap.
Would a complete replacement engine be a more cost efficient option for you?
Perhaps 9-apart or Jasmine Porsche could supply one at a lesser cost? May only be a band-aid fix and perhaps a rebuild is the way to go though.
On the technical side, what are some of the causes of bore scoring? I read that it does have a lot to do with temperature
Yeah, getting scored cylinders on a toy you dropped over 100k on would sting a lot more than my sitch. I get it that most engines need a refresh after a while, I really do, but we're talking about a car that has 60k miles on it. my DODGE truck has 105 000 miles on it and all I've ever thrown at it is brake pads, rotors, oil and filters.
Hi Roo
Sorry to hear about your bad luck , I take it your in the Uk like me , you can do it for less than 10k lots less especially if you don't mind getting your hands dirty, you can get a good low mileage engine in exchange for about 4.5k or have yours repaired , Hartech and Cath Burrows Porsche in the North west both offer this service .
Lee
I don't know. We did buy our's new ($103US I think it was) and while it would suck to lose the motor, we've gotten 15.5 years and 70k out of it. During that time we've done a bare minimum of maintenance on it, ran it in sub-freezing temps, yet the motor hasn't given us any trouble. The only really bad thing was having to rebuild the transmission this year.
I'd certainly be irritated at the money we'd have to spend to revive it, but that original purchase price wouldn't factor in to the pain in my opinion.
Now if I paid $20k or less for it and had to rebuild/replace the motor after only a few months/years of owning it, then I'd likely be more pissed off.
Yet contrary to your constant obnoxious trolling, it's been a perfectly fine motor with no issues and without the need to take it apart every 10 miles.
OMG we've run M1 in it for it's whole life too. The HORROR!!!!!
Not one bit of regret or angst over what we paid for the car. It continues to be worth every penny.

Yep
Sorry to hear the bad news...In case you need more options for rebuild, my shop specializes in engine repair we have a second location in Poland, we could help you arrange transport as well. Our rebuild cost for 3.6l is 8,000 Euro, motor comes with 6 months warranty. Installation is included in this price, fluids, ac recharge and all the good stuff. We deal with a lot of cylinder scoring issues and resleeve cylinders with special steel sleeve technology which eliminates scoring or d chunk issues for good. We just had a customer drive from Vienna to our shop in Poland today for IMS replacement, our company works with customers all over US and Europe. You can also ship your motor if you prefer to install it locally, that's not a problem. Fell free to contact us anytime for further questions. You will find a link to our Facebook page on the left or click on MB Motorsports to visit our website.
AWDgyu,
Where in Canada are you? I have my M96 engine completely apart on a work table waiting to be put back together (have another Porsche project that needs to be finished first). If you need help pulling your motor, let me know. Have an ATV jack that works really well.
