Don't try to pretend there are no problems in fear it will hurt your cars value. There are real propblems, not with every car, not with most cars, but few too many based on my own personal basis. 1999 996 61K mi - Engine Toasted - Cyl # 2 failed.

toolpants: do you have a picture of a rod being thrown through the block? curious to compare..

So how about a rod through a piston instead?

I drive hard and rev high every chance I get without abusing it - just like it was made to do... every single day. 85k miles and I don't burn or drip any oil and it's as strong as ever.
When my car turns 100,000miles I may put in an EVOMS supercharger.. just for because.

Toolpants,
Thanks for the pictures. I've followed much of your input (especially with respect to Boxsters) for some time now - very informative. I have a question regarding engine failure in the 3.6 cars. I'm assuming this is a much more rare event than in the 3.4 model (mainly due to sleeving problems on the 3.4s). Is this an accurate assumption? Frankly, the only issues that have a hesitating (and only a small bit) are intermediate shaft and slipped sleeve issues resulting in engine failure. The RMS issue is manageable for me.
TIA,
Joe
1995 Porsche 993
1988 BMW E30 M3 2.5 (240HP) daily - SOLD - probably will replace with a 996 3.6
1988 BMW 325is - mine again

jm: check the 84 engine replacements thread and you will see that the engine replacements are pretty fair distribution wise between 3.4 and 3.6.. doesn't seem to matterf.. although 00 and 01 seemed to be a good year..

Well, if and when I need a new engine, let's hope they've corrected whatever it is that's prone to failure. So far though, my engine seems pretty solid. I wonder if it has anything to do with how I 'broke it in'. I recall hardly ever shifting into sixth gear, and keeping the revs between 3,000 and 5,000. I think one of the worst things for these engines is to push them in a high gear at low revs. That, and downshfting from fifth to second at speed!

However, the low mileage also be one of those situations where if it is defective then it blows more quickly similar to what they say about electronic items in that if they are going to fail they will more likely fail early vs. later if they are going to fail (abuse notwithstanding obviously).

There's no evidence that driving at lower RPM ranges would cause an engine to blow. I'm very skeptical that it would. Even if it would cause engines to blow, why would it only occur on Porsche engines? It's inconceivable that only Porsche drivers would drive in a manner you believe to be dangerous to engine longevity. If you visit other car performance forums, vette, M3, viper, you won't see any threads focussing on engine replacements, at least not on the forums that I visit.
I believe that it's unfair to suggest that the drivers of these cars with blown engines are somehow at fault. It's far more likely that they had defective engines. Unfortunately, we don't have any way of determing just how widespread the problem is. Only Porsche knows for sure, and they aren't talking.

I wasn't impying that drivers are to blame for their engines blowing (although a small percentage probably are due to driver error or abuse), but I was just pointing out why my engine may have been spared any problems.

the ppl in the vette forums are complaining about plastic dashes and falling off interior trim
