Cracked block on a 05 C2S.
#31
Over revs would have nothing to do with the cracked cylinders. Over revs damage valve trains and con rods, possibly cranks. Cylinders don't rotate.
Any chance the block was the victim of a hard freeze?
I'd guess either that or it's a defective block.
Maybe it had a slow head gasket leak. You said car was parked for a while. While car sat, head slowly leaked coolant into cylinders. When you then cranked it over with said coolant in cyl it hydro-locked and cracked two cylinders.

The month that it sat we had some temps in the mid 20's. At those temps you need about the same ratio of coolant to water as vermouth to gin in a dry martini to keep it from freezing.
Hydro-lock sounds like a likely culprit. but at this point there is no way to tell.
What really sux is that I needed to rebuild the calipers on my track car before the DE at TWS this weekend and I've had to use it to get back and forth to work so that didn't get done.
We will be escalating this. Or ,in the immortal words of John Paul Jones, "I have not yet begun to fight"

1. This kind of damage is NOT covered under CPO because of section x.y in CPO paper work
2. This kind of damage is NOT covered under CPO due to engine abuse/tracking/DME , etc...
3. Flat out denied the claim at dealer without proper explanation?
Thanks

Hey Paul... just trying to clarify what EXACTLY did they say about your situation?
1. This kind of damage is NOT covered under CPO because of section x.y in CPO paper work
2. This kind of damage is NOT covered under CPO due to engine abuse/tracking/DME , etc...
3. Flat out denied the claim at dealer without proper explanation?

Since the buy out by VW it's been my understanding that they are running a much leaner ship now. Thus, they will attempt to duck around as many of these issues as they can. Best of luck. It looks like it's their responsibility, or it will certainly get out on the street that these cars have a finite life--and it's not that high.

pmgoodwin, man I really hate this for you...it really stinks! 55k miles is not all that much. Please keep us informed with what Porsche says.

Paul, was the car stored outside in the rain during that month it was parked.
I've heard of 996's that got parked out in heavy downpours that had front trunk flooding that got sucked up by the brake master cylinder vacuum line. Water gets ingested by engine, pistons hydro-lock and crack the cylinders.
Check the front trunk for signs of moisture.
Any word from Porsche on this yet?

Well that is good news. They definitely should.
Paul: In case you need ammo, below is a pdf file on the general reasons for cylinder cracks. The article is comprehensive and dense. Probably best to read the entire thing; but for the cracked cylinder info start in at page 8. Note that the article is for M96 Porsche 3.4L to 3.6L engines - But M97 engines use the Lokasil cylinder liners (p.10) so the info re same should be applicable (the GT1 block still uses Nikasil, IIRC) - heres TMI on the Lokasil liners [ http://www.kspg-ag.de/pdfdoc/kspg_pr..._casting_e.pdf ]. I think then that the asserted reasons for the cracks should be applicable in a general sense. If PCNA starts trouble a good independent with this info and experience (Jake Raby, maybe) could help possibly. Hopefully, however, you will not need this. GL..

in an earlier post Fahrer mentioned the D-chunk so I did a little surfing and found lots of pictures that could have been my car. Cello just gave me more ammo. So I'm just gathering info at the moment.
I heard yesterday that there was hope that it would be covered. So we'll see.
My ex never drove the car even before she was ex.
