i have a low compression ls/v built for turbo, heres the deal...theromstat stuck closed head gasket melted car still ran fine but with an oil leak. after puttting in the new cometic hybrid gasket, i had a no start i have spark, 20-160-160-160 compression readings. took the head off no bent valves n cracks in the head cam lobes r fine motor is brand new only 11k on the build so i wouldnt think rings. Anyone got any idea on what else to check or do?

 

did you happen to check the block and head to see if they are straight

 

yea when i took the head off i cleaned both up n they r not warped

 

leak down test!it will tell you everthing!!
