sorry to gear that man...but 300 miles is Way too soon for youto have not done something significantly wrong..... only three possibilities come to mind: improper torque,cracked head or block; or the lower timing belt cover was not cut with the block.

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

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.
