why are all of the pistons dirty accept one?
when i pulled the intake mani the second pipe on the mani was pretty dirty down where it connects to the head.

the intake valves are second to the right in this next pic. not sure what the exhaust valves look like, theres one last bolt i cant get off the mani :cussing:http://i55.tinypic.com/ilwzle.jpg
on the valve side of the head the valves for piston 2 were basically clean

yeah it was running pretty rich

looks like the use of crappy gas

Looks like lack of anything burning in that cylinder.

what do you think could have caused that?

Crappy gas would detonate like hell. It's almost like the cylinder is filling up, not burning, and then being dumped back out.

blown headgasket, burning coolant will cause a cylinder to be incredibly clean.

could that have been because of the blown headgasket? maybe antifreeze was stopping the combustion?

thanks for the advice! but im trading the head for a complete ls so i dont have to worry about all that stuff :D

Blown head gasket around that cylinder had coolant or water fuzing to keep it clean. Also may been a dead cylinder all the time...

thats what first came to mind when i pulled the head, what could've caused that? bad spark?
