ok so i oringed the head with a copper gasket...... i was told it was a head gastket problem. we put it back together and the same thing.... only under boost. i was told to retighten the studs because the head was lifting. i was also told to check the thermostat and the radiator cap...... any suggestions? before i put this new head gasket on you could smell the exhaust in the overflow. now you cant!!!!! im lost. please help

 

if the head & block decked?

and how tight are you putting the head down, what gasket etc etc etc

 

yep the head and block were decked!!!! its a sce copper gasket. i have arp head studs and we tightened them to spec..... does that help at all?

 

i have hondata intake gasket, the block is sleeved, the head is built..... it wont do it under normal driving but the second i hit boost it does it......

 

sorry the motor is an h22

 

you have air coming into the system somewhere. since you've changed the headgasket go ahead and try the radiator cap. why aren't you using a OE headgasket?

 

We were using honda gaskets and it blew under high boost..... so that's when I took off the head and had it oringed....... radiator cap is my last choice..... anymore ideas??????

 

what ft-lb did you torque it too? if 65 ft-lbs, try 80 ft-lbs.

 

you o-ringed the head or the deck
