well its counting down till tune time so i figured check the compression in the ole ls and got some sad results.
came out at 130-130-120-125 at operating temp, WOT cranking.

the car has a little bit of an oil smell out of the exhaust but doesnt burn oil as far as i know, ive only driven it 1500 miles so far. i havent tried to pour oil in the cylinders and check it then i will do that tomorrow.

how can i check to see if i have any bent valves? im guessing only a machine shop can help me with that.

i suppose next thing to do is a leakdown test.

anyways i know this is a pretty lame post im just trying to figure out wtf is going on... i need to have this car running by the 28th for tune day and i dont really want to buy another ls but time is ticking. any input guys?

dose the motor have aftermarket cams? also test with a diffrent gauge. leakdown test will show if it has bent valves

compression is really low. HG most likely bent valves I doubt it unless that motor was rapped on factory b series motors rarely bend valves unless the motor loss a t belt at one point of its life and wasnt fixed

stock cams, is there anyway i can test to see if its head gasket? i dont have a leakdown tester available yet.
