I recently picked up a cheap endoscope for iPhone and thought I'd check out my pistons while changing spark plugs yesterday. 2000 996 C2 3.4L w/104K miles.

• Four of them seem to be lightly pitted and two more so.
• Cyl 1 is a little blurry in the photo, but it looks more like 4 or 5 than 2 or 3.
• Cyl 1 and Cyl 3 have what looks like a valve imprint, at least in the deposits on the surface. Could that mean deposits on the valve seats?

What do others see?

Bank 2

At least it wasn't....


1982 ALFA GTV Piston
That happened on the Autobahn in 1989. I've kept it on my desk ever since. An expensive reminder to not be stupid.
