This is not a new phenomenon with 911 engines. It has been happening ever since the model was in existence. During the 1980's and 90's, Porsche would replace the engine for free, even if the vehicle were out of warranty in some cases, if the owner would sign an N.D.A.

I appreciate the answer, but i was also wondering why would this constantly happen, especially on motors that are deemed to be so race reliable?

Where are you getting your data - not sure I would characterize these failures as "common" or "constantly happening".

I'm not sure about the misfire codes. Where/how are they displayed? I believe the dealer has pulled them. They said Porsche would want to see the codes, but didn't say if they revealed anything about the source of the problem. I'll ask tomorrow.
Nearly 20,000 miles here. Will be at 20,800 after this weekend.

Sorry to hear about your car. Allot of us with 997 gt3's are real interested in what they determine as the cause so please keep the board posted when they give you an answer.

as far as modifications, since you are using Porsche approved parts I do not think you have any problems. You did not tell us if your use was track or street. the Manual does state that they will not cover any damage that occurs on the track,(it is hard to prove that by the way as to where it happened) but I have been told that P is vary liberal on that. they don't really care about tracking the car as that is what they marketed it for, however Abuse is a different story. You can track your car without going over the redline all the time. So engine codes will be important. Good luck.

Could you please document this for us so that your words "common" and "constantly" match the definition that Webster has in the dictionary.

Main Entry: 1com·monPronunciation: \ˈkä-mən\ Function: adjective 3 a: occurring or appearing frequently

Main Entry: 1con·stant Pronunciation: \ˈkän(t)-stənt\ Function: adjective 3 : continually occurring or recurring


If this is the case then why did you buy one? in fact why would any of us buy one? Warranty or No why would anyone put themselves in this situation it it were so common?

For a first post on this forum, I may incite a flame war. That is okay.

Once Porsche moved away from the air cooled engine in 1999 to the M96 wet-sump engine which can be found in the 996 & 997s, there have been a significant increase in reports of engine failures - especially on the track due to oil starvation. Porsche did maintain the race-tested 964/GT1-derived dry sump engine for the 996 & 997 Turbos, as well as GT2 & GT3s. This engine has proven to be unbelievably robust for the track environment, though Porsche has been putting the M96 engine through the paces as it is the engine run in the Koni Challenge.

So to answer your question - to which 911 engine are you referring? It has become quite clear over the years that the failure rate of the M96 engine far exceeds that of the Turbo/GT2/GT3 engine. However, we hope that Weissach will continue to improve upon the cheaper-to-build M96 platform and bring it up to "Porsche Standards" over time...

Because Porsche and most other manufactures are "getting cheap" on build quality. I have an older 911 and have been around the newer 911's (water cooled) and I have a tech background....these new motors are nothing like the bulletproof motors of the air-cooled ones of the 80's and 90's. You will see prices starting to creep up on the older ones as demand will surge when people find out these new cars basically "hot rodded subarus"

Ohmaha, any word on what happened to your engine? Did Porsche put a gag order on you? You can't drop a bomb like my engine seized up and then go quiet

Omaha I am very sorry about your GT3.
After I had an RS OEM singlemass LWFW installed in my GT3 there was my incident. While driving the temp went to the moon and I had to immediately pull over. My diagnosis was that my crank pulley became undone and destroyed. This took along time to get fixed because the pulley could not be obtained from Porsche Motorsport in a timely manner.

I had aftermarket headers on the GT3 and this was not brought up as an issue.
My GT3 since that time was fixed and has been running perfect. I was worried that there may have been internal damage after the incident. I wanted a new motor but NO deal.
My car runs stronger than ever and has dyno'ed 392 rwhp as of the last visit to Champion Motorsport. There are more ponies to come and the motor has not skipped a beat since the pulley problem.

Omaha sorry to hear of your problem but it will get solved and your GT3 will be back to what it was.

Good luck, GT3Ranger...Juan
