It's that time again! Just did the 2100 hr oil change and took a peek at the valves. Oil filter and suction screen had some crumbly carbon bits in them, but no metal I could see. The magnet on the filter had a thin film of micro iron stuff that wiped right off.

Compressions were 77/72/78/77. #2 has shown a bit low before, but typically comes back on the next test.

here are the Exhaust Valves I added some "pop" in Google Photos.....

#1

#3

#2

#4

One intake valve - because I thought the color/pattern was cool.

Excellent quality images. Could you tell us what type of borescope you used, and what type of fuel?
Cheers,

Hi Tom,

It is little usb camera on a wire - there are several that have been listed here previously(I don't have the link handy). I run mostly 92 mogas - some 100LL on the road.

Excellent quality images. Could you tell us what type of borescope you used, and what type of fuel?
