Compression

[Kyle91rs]

So I'm starting a tear down of my sled to install a stage 2 ovs, and I done a quick compression test just to make sure everything is ok, and it came back as 170 on each cylinder.... Doesn't that seem a little high?? I have about 1500 miles on the old girl, and they weren't easy miles, I wasn't expecting it to be that high!!

Ya what he said. Check it warm. It'll tell you more about what's going on in there.

Well it's been sitting in my heated garage for 2 weeks without being started prior to the test.

By warm I mean operating temperature.
