Is this DME readout good/bad?
1) 526 @ 691hrs
2) 147 @ 385hrs
3) 95 @ 385hrs
4) 81 @ 385hrs
It has 81 ignitions in Range 4 with 380+ Operating hours. That equates I believe to .2s in that range.
The engine is getting worked on now after the dealership noticed metal shavings. I was told that they're tearing it all the way down to the crank and there was bearing material and that was the metal they found. They have put "all new rotating assembly, bearings, studs, bolts, gaskets, rings.". Is this work sufficient to account for the rev history?

type 4 is 9600-10,000 rpm. Any time actually recorded there can't be good. Don't forget it spent time in ranges 1,2,3 to get to range 4. Someone can correct me if wrong but I think only the peak zone is captured so figure there's still a much longer time it was over-reved to get to that peak of .2 seconds > 9600rpm
How many hours on the motor since the over-rev

Truth is that no one in this forum will be able to answer your questions accurately. Looks like one bad downshift (mechanical overrev). Driver probably caught it relatively quickly, but still generated range 4 ignitions. You should just walk away from this one. Not only are you taking a chance, but your resale will take a hit too. Why so interested in it? .. price? Is it a 997.1 or 997.2? How much?

If a claim is made in the future, Porsche may deny stating engine abuse. Or they may honor. Who knows? Dave
