jacob80 Posted May 31, 2009 Share Posted May 31, 2009 Hey guys, just wonderin if a compression test of between 125-135 for a freshly rebuilt L28ET is good. The engine seems to be running great with no issues, except a couple small tuning issues. Just let me know, thanks guys! Quote Link to comment Share on other sites More sharing options...
X64v Posted May 31, 2009 Share Posted May 31, 2009 Yes. But what you're actually looking for is consistency in the numbers, not the numbers themselves. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted June 2, 2009 Share Posted June 2, 2009 Especially since the rings have probably not bedded in fully yet... Quote Link to comment Share on other sites More sharing options...

jacob80 Posted August 17, 2009 Author Share Posted August 17, 2009 Our engine has a decked head and sum-1mm Felpro head gasket. What results has everyone else achieved with their motors? (Turbo of course) Quote Link to comment Share on other sites More sharing options...

(Turbo of course) my l28et compression was 130psi on four of the cylinders, 131, and 133 on the other two. this was on a short block from a junkyard Quote Link to comment Share on other sites More sharing options...
