Sorry to hear that man, ive got a new headgasket if you need it

[cre]

did you chase the head bolt threads with a tap? torque in multiple passes and in the right order me?

as long as the head and block aren't warped I'd redo the HG.

even though i followed the tsrm i just wonder if i just f'ed something up of whatever. also i didnt get the new head machined but i did buy a rebuilt one on ebnay for $400 and it says it was already shaved and ready to be slapped on. you think i might have messed up on the head bolts?

Did a shop rebuild the engine for you? I know a person who got there motor rebuilt, and the shop torqued the head bolts at the wrong torque, because it was listed wrong in the manual. He even told them to change the torque because it is a problem, but I guess they did not believe him. In the end the tech had to rebuild the motor at no charge, but they bought a replacement instead I guess cheaper. It took some time to get it back, but if some one did this to you, you can get it at least get it fixed at little to no charge.

no i actually did it myself and torqued them down to 80lbs. but i think cre might be right about the chase and tap. too bad i dont know what the hell it is.

hey cre would i still be able to use my arp bolts?

Chasing threads is a pretty standard practice. You get a tap (thing used to thread holes for bolts) of the same size and pitch of our headbolts and you thread it into the holes (and keep adding oil to lubricate and clear out debris). As you thread it in AND as you thread it out it cuts the metal of the threads back to the right shape and size for the bolts/studs. Not doing this may cause the bolt to reach a given torque level but not provide the actual axial clamping force you want (ie: the shit don't turn so easy so you think it's done too soon).

I really wish they made hollow studs for our cars.... that's the only way to get really close to a given clamping force. Hollow's are great.

Yes, the headbolts are reusable.

80lbs is high... don't go over manufacturer specs just becaust you think it'll be better... you'll break something.

Also, rebuilt of not, you don't know what shape the head was in... could have warped from inappropriate storage. Measure it with a machinist's straight edge (not just a metal ruler! ).
