Engine freshin up

[juic3d]

Ok since I did the compression check on all cylinders and getting no more than 85 to 90 pounds. That I am assuming very weak bottom end. I'm assuming my pistons are still good. What would it cost to have it all gone threw a d freshened up. Will be changing cams at the same time too

you need some zmax in there.

correct me if im wrong but doesnt a compression test check ring/valve seal how would your bottom end affect that on every cylinder

[juic3d]

Yea I was thinking the same so what does it mean if all the valves are the same

Compression test being weak an all cylinders is likely a ring seal issue. With that being said did you do the test correctly. All 8 plugs pulled and throttle wide open when cranking. In general if all that was done you look for a variance in one or a few cylinders. Anything over 5% differnce between cylinders. So one cylinder at 90 and others at 125 is a problem. But all cylinders exactly at 90 leads me to believe the test was flawed in some way or the gauge reads low.
