I just rebuilt my gsr motor for a turbocharger, and I had a machine shop bore it out for oversized pistons and did a complete head rebuild (including resurfacing the head). I put the head on with arp studs and an OEM head gasket with copper spray, but it seems to be leaking oil from the head gasket somehow. Why is this happening and how do I fix it?

 

anyone?

 

did u tourqe the arp studs right they mit not be tourqed down enough

 

Did you have the head and block decked before you reassembled the motor? I would just recommend pulling the head again and checking both surfaces with a straightedge for warpage. Also were both surfaces (block and head faces) cleaned off? Just a couple other things to think about.

Are your stud's all the way down in the block before you torqued the head?? If not, Your head gasket is not going to seal properly. I had the same porblem.
