TheNeedForZ Posted April 22, 2007 Share Posted April 22, 2007 I am receiving a complate LS1 engine (1998 Camaro) without transmission(originally a 6-speed) in a few days. It has just over 100000miles on the odometer. I know the GM bottom end are very long lasting, but what do I need to check once the engine arrives? Thanks Quote Link to comment Share on other sites More sharing options...
myplasticegg Posted April 22, 2007 Share Posted April 22, 2007 start by checking the compression, wet and dry. more will chime in... Quote Link to comment Share on other sites More sharing options...
TheNeedForZ Posted April 22, 2007 Author Share Posted April 22, 2007 How do I check compression? Does it require a running engine? can you elaborate on "wet and dry"? Quote Link to comment Share on other sites More sharing options...
Hey_Allen Posted April 23, 2007 Share Posted April 23, 2007 To the best of my knowledge compression checks do require that the engine be runable. Dry is just putting the compression tester in the spark plug hole and cranking it over a couple of times. Wet testing is the same, but you squirt a little bit of oil in the spark plug hole before running the test. The difference between them typically is an indicator of piston ring problems, if the pressure on a cylinder comes up dramatically when wet.

myplasticegg Posted April 23, 2007 Share Posted April 23, 2007 You're looking for it to be even, not so much high. Hey_Allen got it right on. If your compression shoots way up in a cylinder when oil is in it then you need to do a little digging, or some gambling. But if they all go up about the same percentage then you're good to go.
