Ok i have a problem with blowing head gaskets now...Anyone know of a good thing to do first i replaced the injection pump then about a week later i blew my head gasket. Ok got that fixed on monday and it blew again thursday. And i got the ARP headstuds put in when i got the head gasket replaced and like i said it blew again in 3 days. Can anyone give me some advice on what i should do or what would hold up. Im running 45-47 pounds of boost.

 

You have to let the studs get a few heat cycles in them and a few retorques before pushing alot of Boost.

 

ok so you think the stock head gasket will hold up to 47 pounds of boost?? and explain about the heat cycles i have been seeing it on here alot

 

You have to get the engine to running temp then let it cool off. Do this a few times and re-torque the studs. Id do this 2 or 3 times.

 

but when you say retorque the studs do you mean go through and loosen then tighten or jus check them to 125? and also do you think that the stock cummins gasket will hold up to that much boost or will i have to go another route?

 

Did you have the Head and block checked for flatness?

 

I would have the head decked

 

yea the shop said they had the head checked for flatness they said the only thing they didnt do was magna flux the block i think thats what its called. But they said everything was good

 

They have to take any material off the head to make it flat?

 

nope the only thing they had to do was something with the valves i cant quite remember what it was but they said they wont seatin right or something but that was it
