mechanics diagnosis on overheating - 4/25/2008 12:52:19 PM    zero lash   Posts: 2 Joined: 4/25/2008 From: 98 4x4 lt Status: offline My truck overheated. The cylinders were reading around 30%. The mechanic suggested removing the head and checking for damage or just replacing it with a used motor. What should I do? Post #: 1

Did he mean 30% of what the compression should be? I wouldn't jump right into a new engine unless I knew whatever was wrong with the one I have is more expensive to fix than buying another. If the bottom end is okay, having the heads redone is probably cheaper than buying a used engine (if the heads are the problem, of course). P.S. Probably doesn't matter in this case, but it can help a lot if you post a description of your truck (year, engine, 2/4WD, etc) in your signature. _____________________________ 2000 LT 4x4 '81 Harley Sturgis Lowrider (in reply to zero lash) Post #: 2

If it was ran until it couldnt without coolant than im guessing its going to be complete rebuild of those cylinder which will turn into more most likely. It is probably going to be easier to swap it out, but you may want more quotes 16hrs install seems a bit much but I could be wrong. _____________________________ 1997 Olds Bravada AWD 4.3L Auto ~34,800mi(high idle time) (in reply to zero lash) Post #: 4
