Default 2008 Cayman Rev Report

Hey Guys, I'm brand new here and working on a deal for a 2008 Cayman S with a 6spd. I had the PPI done today and would like to get your opinion before I continue the purchase. I've been reading as much as I can but it seems like alot of different opinions when it comes to the rev report. I understand a person doesn't want to see anything in the 4-6 range if possible correct? Is the range 6 number possible without seeing it in the other 5 ranges?

RANGE 1 - 5766 - 641.8 HOURS
RANGE 2 - 204 - 641.8 HOURS
RANGE 3 - 16 - 641.8 HOURS
RANGE 4 - 4 - 222.7 HOURS
RANGE 5 - 4 - 222.7 HOURS
RANGE 6 - 3 - .4 HOURS

Thank you in advance, Craig

Hey again, I didn't get any responses on this one so I'm going to pass on the car. I had a full PPI done and would definitely encourage others to do the same. Well worth the money.

Thanks, Craig

Craig,
I will qualify that I am not any sort of expert on overrevs on Porsche M97 engines, but I have read many times that level 4-6 are the dangerous revs.
However the duration of revs in each level (number of engine revolutions) and when the overrev incidents happened are the most important factors.
For example if the overrevs occurred at 222 hours and the engine currently has 700 hours and there is no sign of rod knock, oil consumption, or valve damage, then I would be far less concerned than if the overrevs occurred at 650 hours.
I'm sure those that DE, autocross, or even race their Caymans could give a more reassuring answer as to just how "bad" overrevs are.
I suspect the car you were looking at was just fine as far as overrevs were concerned though.

Good move!

Here is a good explanation of the over revs:

Looks like it had a missed shift on a test drive or first drive...

It did one revolution at stage 6, 1 1/3 revolutions at stage 5 and 1 1/3 revolutions at stage 4 and 5 1/3 revolutions at stage 3. The three stage 6, three of the stage 5, three of the stage 4 and three of the stage 3, three of the stage 2 and 3 of stage 1 all occurred on the same event, likely a missed shift. It had another missed shift at some point as well were it picked up another 1/3 revolution at stage 4/5.

Default Over Revs or Ignition Events

A friend was looking at an '06 Boxster recently so I did some searching for over revs for him (among other things; e.g., water pump, rear main seal, clutch cables, etc.) before he has a PPI done and came across this post. I also looked through my old "Excellence" magazines for an article I remembered and found it in issue #215, December 2013. I put "stick-ums" on the magazine covers when I see something of interest so I can find it again fairly easily. According to the author of the article, "Porsche is more likely to forgive certain over-rev events if the motor in question has accumulated at least 200 hours since the occurrence, the thinking being that if the motor has been okay for that amount of time, then no damage was done." His words not mine. I certainly wouldn't pass on an awesome deal if there were one or two occurrences of short durations in 5 or 6 AND it met the >200 hours criteria the author noted and Spokayman eluded to. Great bargaining tool if noted during the PPI and the seller hasn't read this article. I'm sure there are a lot of other opinions on this subject.

Hmm, judging from the chart, perhaps I should stop using the rev limiter as a handy upshift indicator.
