Default DME Read Out from PPI...Anything I should be concerned about?

Below is a read out of the Over Speed and Misfires. Looks like there were quite a few misfires. Anything on here I should be concerned about?

This is for a 2010 911 C2 6MT with 51k Miles.

This.

You need to put the car into misfire tracking mode and see if they're still happening and on which cylinders. That's a lot of accumulated misfires and when the car is misfiring, raw gas is moving through the cylinder washing the oil from the walls.

My previous 997.2 C2S showed 24,547 misfires over the life of the control unit. This was on a 32k mile car. Never had any engine issues with it.

Over revs look fine.

Over revs look like the car was never driven hard. No concerns with over revs

Wouldn't those be more for a .1 than a .2?

on a 997.2?

cam deviation report?

bore scope?

If a buyer was asking me for this I'd go tell him to find another car because there are 10 other people lining up to buy it without the hassle of the above. Selling a Porsche sucks these days, geez.

997.2's are subject to Bore Scoring especially cold climate cars. Small % but as precaution I would not hesitate to have a 997.2 BS Insp.
I also think Cam Deviation is part of the 997.2 DME readout and important as a wear indication.
