Re: whats wrong with my motor...lol
 

yeah we're gonna get drunk and do the compression test tonight...lol...if the motor is bad i have my other ls sitting there we can swap in...and if that ls goes in...it's time for me to go turbo again :)

Re: whats wrong with my motor...lol
 

mine did that once, check you injector clips. that was my problem. or your pulgs and wires first.

sounds good eh?!? ;D

Re: whats wrong with my motor...lol
 

basically you have a cylinder not firing...could be loose wiring at ecu/harness, injectors, plug wires...

or it could be a cracked sleeve/melted piston

Re: whats wrong with my motor...lol
 

Trust me...you'd know if you had a cracked sleeve on boost...been there. When my sleeve took a ---- it pressurized the cooling system and shot all my coolant out the overflow like a pressure washer ;D Pull the dipstick and smell the oil...if it smells heavily of gas (most of the time it does, but not always) you probably torched a piston :-X

mine is all motor for now...compression test was 220 across the board on my ls...we found out it was a plug wire prob.

sounds like you blew a headgasket. Out of my experience, when my car sounded like a Subaru STI with open downpipes. My engine blew a headgasket and there would be tons of white smoke coming out the muffler. Good luck :)
