Maybe others understand the significance of Jake's photos but I don't. What are we seeing here?

Those are the remains of his main and rod bearings as found in the oil sump and oil filter housing.

That's just wrong at 75k on a well maintained motor if you ask me. Neophyte question, but I'll ask it. Main and rod bearings mean this wasn't an IMS event?

I would like to know the most likely cause for this failure as well. The only thing I can think of might be a poor oil film issue. Shocking for an engine with only 75K on it.

Dealer diagnosis = spun bearing

Flat-6Innovations diagnosis = __________

If really a spun bearing, then I ask this: Really no over revs on that engine? Really?

Is the amount of sludge normal ?
Was it really well maintained with good oil and annual service ?

Thats not sludge. Its chunks of metal debris from the failure. My guess is this engine has been religiously lubricated with liquid death at the recommended intervals, which are far from adequate.

Just another normal day at the Morgue, here at Flat 6.

This is more than a spun bearing, it may have started as that, but now the collateral damage exceeds the damage caused by the primary failure.

No biggie. We've got it... I wouldn't know what to do if we saw a car actually drive into the facility that could be repaired in one day, or wasn't scattered to bits.. We've had ONE elective build in the last 40 engines here.

By liquid death are you meaning OEM recommended oils? If so, what do you recommend and at what interval? How much should your driving style influence your interval? Probably a dumb question, but I would like to believe Porsche would set its intervals based on a reasonable amount of spirited driving.

Fascinating thread to follow. Really feel for the OP. These are the stories that scare the crap out of me, especially since there is a recent theme of after market warranty coverage drying up/getting ridiculous in price (implying to the digit head here the probability of a catastrophic event in these cars is significant).

I'll have to bow out of this thread now.. I have learned over time that we simply cannot discuss failures at all without being called fear mongers. That comes simply from sharing the experiences that we face every day here as developers and working to save these engines.

Lets just say that the factory recommendations were made as "projections", and that practical application experience, here in the real world that things are just not the same.

MY oil recommendations are totally biased, because I've worked to develop 4 different oils from scratch.

I let the original poster share what we find here in the thread if he wants. I've already received a PM about this thread that reminded me that I don't belong here.

Well I don't think you are fear mongering. Just want to learn. Obviously respect your choice to bow out. Would welcome a PM if you do wish to privately share wisdom. Cheers.
