I directly asked my service manager how many engines he has had to replace and he told me he averages about 2 a year. While that may be 2 too many, it makes me feel a bit safer. I asked the question when I was there having my ignition switch fixed and on that one he sayes he does about 10 of those a month.

While I have no doubt that engines do fail, I think the risk remains low and within the limits you would expect of a car that gets driven a lot harder than your average car. I know that driving a car with more than 100,000 miles on the clock is running a risk for a lot of things, but I still can't find anything that I could get for the equivalent price that gives as much driving pleasure.

01-04 3.2L 986 & 3.4L, 3.6L have IMS failures and cracked head issues
May I conclude '00 year is the magic year? I have one.

You are assuming that your service manager is free to speak on the subject - which he isn't.

Porsche ask owners to sign Non Disclosure paperwork when they have an engine replacement, so you might imagine that dealership personnel are under even tighter control as to what they can publicly discuss.

I tend to doubt that. I have a good relationship with this service manager and he has always been upfront and honest about these sorts of things. If he was under a gag rule he would have probably said he couldn't say or said none.

While I don't doubt that Porsche itself would never publish these kinds of statistics, I doubt if they would or could control what an individual service manager or mechanic or anyone else working at an independently owned dealership says. And if they did try that, I think someone would have reported the gag order on this web site. There are just too many people involved to keep that kind of a thing secret.

I had a transmission replaced under warranty and there was no disclosure statement involved in that. Are you sure every engine replacement under warranty requires a non-disclosure statement?

I swichted off the car and sent to my specialist and confident mechanic.
He was on Portugal for a hollyday and till september 4th, will not come back. So I don't know what would happen to my loved p-car yet.
let's hope everything turns out all right! I am dreaming about it'd be the oil pressure sensor... if not, you know what we are talking about


The car has only 26.600 kms




Well, I have good news
My mechanic told me that the oil pressure sensor was "the guilty"
He ordered a new one to Porsche dealer, and that's all.
I was very worried about this, but I can see that God listened to my prayers

Sorry for offtopic, but does 996GT3 also have those engine problems?
Thanks.

GT3 series have the "GT1" block engine with dry sump. It's a very high reliable engine. 996 TT aslo gets the Gt1 block, but GT3 series have a Porsche procedure to clean up the engine if coolant mixes to oil, to avoid change the engine.
It's one of the best engine made by Porsche, and nothing closer to 996 Carrera series provided with wet sump

Just had my engine replaced under CPO 2 weeks ago. Failed intermediate shaft. Non-Disclosure paperwork??? No. If they once did this, they do it no longer.... perhaps just an urban myth.

Anyone else (first-hand) signed an NDA for an engine?

Are you asking for people who have signed a non disclosure agreeemnt to disclose that they've signed a non disclosure agreement? Sort of a "Catch 22"...

Touche - technically. I'm sure the NDA, if it exists, stipulates not disclosing the specifics. However, having a rennlist member simply state that they signed an NDA probably won't unleash the legal hounds at PCNA to hunt someone down....

Of course, I make no warranties as to this, explicit or implied, yada yada yada -


I know that IF I were to have signed one, I wouldn't lose any sleep posting a reply - but feel free to PM me if you want to conduct a "secret anonymous survey!"

GT1 based motors will take more abuse and are more reliable short term, but they wear faster and need to be rebuilt sooner than the M96 engines.

My 03 M96 X51 has over 500 race/de hours on it with no problems at all. That is at least 4 rebuilds on a cup motor.

Those are interesting points Ed... Maybe this is the reason why Porsche are dropping the GT1 blocks....

Hmmmm, then how do we know you did not sign an NDA? Perhaps you signed an agreement to state that you signed no agreement?
