[DKJones96]

my compression reads 180 across the whole engine...but my 5m has 9.2:1

Just a quick add on here.

Compression test vary quite often by who's gauge is being used.Look for even #'s with a max.10% variance.

Had an engine once at Nix.Tested 180 on the tester we had.Customer installs this engine,runs good,but his gauge says 110.He calls and blows a friggin gasket,calling me a liar,among a few other choice words.Sceduled the guy to show up the next day.Had Nix's gauge,his gauge,my personal gauge from home.Nix-180,his-110,mine-170.He hung his head,apologized,bought some more parts. 8)


WADE-Nice #'s keep up the good work :wink:
