Is 60 psi good compression? Is that the normal roughly? Thanks
ouThe important thing about doing a compression test is not how high it is, but if it changes. You say the last test you did showed only 60 lbs., well if the next time you do it it only shows 50 lbs., you’ll know something is going bad. It’s quick and easy.
I can see the advantages of doing a leak down test, but the compression test is so fast and easy, and it can save you a lot of time. I don’t know, but I wonder, is there time to do a leak down test between heats?
So if you do the quick and easy compression test, and it’s down, you know for sure it’s the rings or the valves, so when you get home, you check with the leak down tester
Listen, if you go out in the first heat and you’re slow, you want to know why, right? A quick compression test will tell you right away if you’re down on compression, maybe not if it’s the rings or the valves, but it will tell you.
So right away, if you do a “quick” compression check, and if it’s not down at all, you know it’s not either one. Very quickly you have found you may have some other problem.

I 'Complement' you AL! (I'm gonna take up a collection and buy you a L-D tester!)
could you remove the rockerarms and get a good reading on compression? if so what should you get?
