[QUOTE=Manifold;18595535]Wouldn’t installing flawed replacement engines potentially lead to a class action suit?

I would have to say yes, the .1 engine still after replacement has failed.

The odd thing about the 991.1 engine is that it seemed to be developed in front of the new motorsport engine that was going to replace the Mezger engine.

We are throwing around the term flawed. Who knows all the legal ramifications of the path Porsche has taken to address the engine issues.

Manifold

My first engine failed at about 30k miles. Second engine failed after 8k miles. Now on third engine with about 4k miles on it. I would expect an engine protected by PDK and getting properly serviced to last at least 100k miles.

No debate there. Seems as though a reasonable person would consider that an example of a flawed design (with some basic assumptions re use, lack of modifications, etc.).

This sums it up for sure, the .1 still engine has problems, Porsche should put a 120k mile warranty on all .1 engines.

Could you please clarify for us -- which engine revisions failed in your vehicle? G6 or both earlier variants?

Has anyone tabulated Engine failures against Engine Oil Analysis

ipse dixit

Maybe Porsche, but not likely.

And not sure what that would show.

Any correlation would be subject to so many variables -- i.e., type of oil use, oil change intervals, driving style and conditions, etc. -- that the data would be meaningless. Plus, you'd have to worry about how truthful people are in reporting the aforementioned data.

UOA data is nice, but unless one knows how that owner was actually using the car, it's just data.

He had a bottom end failure in a replacement G6 engine. Unfortunate and a headache, but still an anomaly.

Makes it a point to post in each thread and omits highly relevant context.

To date, nobody on here, FB groups, etc has reported the finger follower fault on a G6.

I had a blackstone report ~2k miles before mine faulted. Nothing which raised any red flags for them.

Manifold

Thanks for clarifying, I didn’t remember the details. G6 engine having a different failure mode doesn’t increase my confidence in the engine.

My engines were broken in per Porsche guidelines, about a third of the miles are track miles, I use the paddles on track and usually wind up short shifting a bit, don’t get to high revs on the road, and serviced per requirements.

I met somebody at the track in November and he said his 991.1 GT3 is also getting its third engine.

It matters when bad info can take off like a wildfire around here. Until somebody reports a G6 valvetrain eating itself, then we it's safe to assume they're okay until otherwise. I was encouraged by the TPC Racing guy doing multiple 8-12 hour enduro races on his.

Sucks you've had to deal with the headaches and lost confidence in the car but at least you're beating the crap out of it

With all .1 GT3's having at least a year of warranty remaining and as discussed the lack of any documented G6 finger follower failures, I'd only be personally worried if I was a .1 RS owner. There's been engine failures in those and now all of them are outside of the warranty period.

I've been wanting to step up to the .1 RS but it's tough to justify getting out of my car with 2 years remaining on engine warranty into something with the same fundamental engine issues that has no warranty. I drive the crap out of my car right now completely worry-free. At this point, maybe a .2 GT3 makes more sense.

I am curious …

the 4.0 engine was developed as a replacement to the 3.8 engine…and with so many 🤮 3.8 failures why not just start replacing all the engines with 4.0.

seems kinda dumb to ruin your company name and reputation with a garbage engine that causes so many people grief and Headache.

I wonder why not super-take-care of the customers and replace everything with the 4.0 engine and call it a day.

Porsche would look like industry hero!!!!

instead… replace engines with questionable reliability ?

Manifold

I wouldn't say it's 'bad info', I just didn't yet specify the failure mode in this thread, though I did do that in the other thread, hence you guys knowing about it. I hope the G6 valvetrain isn't a problem, but still not good that my G6 engine failed after 8K in a different failure. Also not good that another 991.1 GT3 owner recently told me that he's getting engine replaced for a second time (I don't know the reason).

In any case, I still have two years of warranty remaining on the engine, and I do look forward to hammering the car on track over next two years. Aside from the engine concern (and my having to replace the PDK at a cost of $19K), the car is epic. Took it for a drive yesterday, and even after 7 years of ownership, I was still pretty blown away by the car.
