Minimum wear...looks healthy...average is 156 and minimum tolerance is 128-130 psi.

Looks like mine. At 98K miles, Paisley did a compression check and I had:
1)150
2)150
3)155
4)150
5)150
6)145

I did have bad valve guide seals though but the compression looks decent for a car with 80,000 BPU miles on it.
When I did the test the compression tool had a minor crack on the hose portion of it. I taped it up with sealent and duck tape put still leaked a little. So I figure around 1-3 psi lost due to the minor crack on the hose. I need to get a digital one for better results. The car has 70,000 bpu miles on it so I guess I can't complain about the numbers. The car did dyno at 399.8 rwhp at 434 ft/lbs. Thanks
