Hi mate. PM me the data. Pretty sure you will end up with a replacement engine. It would be good to have the mileage along with track miles estimate and the final prognosis (they will drop the engine and remove the valve covers to examine the rockers). I can send you the TSB and an update by PM...

I figured I would just put in an update. Going on the 3rd week at the dealership and nothing. I did contact pcna. Last I heard late last week was that they were sending more pictures but still haven't gotten the ok to replace motor. I hope Porsche isn't going to just change the top end...

My guess is PCNA is well aware of this link.

Agree ^

I would just use as a friendly reminder to
my dealer and PCNA if my car was stuck in the dealer garage for 3 weeks.

Won't be cheap if all E engine s needs to be replaced again.

It became a quick warranty replacement soon thereafter. Something *is* up--the rapid replacement by PAG tells us they know something. May not be the engine, but they must've seen this before to authorize a replacement engine for that customer, pronto.

More on this: said engine failed leakdown test post-incident trackside. Suspicion of bent valve in one cylinder while car was being tracked.

End of facts there, and the beginning of my interpretation: weak cam rocker mechanism or perhaps valve springs?

So far, PCNA has been useless to me...

That is strange. One would like to think PCNA would keep the customer up to date. What are they doing for you in the way of a loaner?

This is interesting thanks CREX. I'm not sure it's related to our lubrication issue in any way. To date I have not been able to reliably collaborate any trend in failures on the RS MA176 engine. I have two reports of failures on cars entered into the German series for stock production car racing and a couple relating to fire which appears fluid/ coupling related, again in Europe and through third party sources although with some photos in one example.

At this juncture I would have to conclude none of the RS engine issues related to me are linked to lubrication of the RH bank valve train.

It's something we should continue to keep an eye on.

My personal opinion is thAt although the G series and RS engine appears at least to have design changes to remedy the aforementioned oiling issue, that there are still likely series improvements unknown to be made to this engines architecture as the 9A1 engine progresses in competition...
