- Mon Feb 01, 2010 9:33 pm #172547 not completely sure but i do think 90 is good that 62 however im not to sure bout that seems well low to me.

- Mon Feb 01, 2010 9:38 pm #172548 ya i was thinking the same thing 90 sounds okay but the 62 is low

- Tue Feb 02, 2010 3:25 am #172609 why in the hell do you have 8:1 cr pistons in a LS motor?

- Wed Feb 03, 2010 2:45 am #172795 yeah 62psi is bad thats about 6:1 cr or a lil less.. was it previously boosted ? could be bad rings or headgasket.

- Wed Feb 03, 2010 5:37 am #172866 the car is boosted now and what could be causing the 62psi

could be bad rings or headgasket.

- Wed Feb 03, 2010 5:52 am #172872 is there anyway to tell whether its the head gasket or piston rings?

is there anyway to tell whether its the head gasket or piston rings?

without taking it apart ? removing radiator cap (when car is cold!!) lol and turn over engine usually the coolant will spray out the radiator due to compression going into coolant passages in the block and out the radiator being headgasket.. thats only if its blown near coolant passages.. could be blown near oil then check oil for coolant.. otherwise all i know is take it apart and replace it ??
