hey i have a jdm gsr with a built b16 head and this summer i decided to put ctr pistons in it. when i got it done and put it back in the car the head leaked oil hella bad, so i took the head back off and got it milled just to make sure and i got some oem headstuds that have only been used ones. i put it back on and it doesnt leak on the one side but by the timing belt it just pores out i dont know whats up with it i torgue everything down correctly and the torgue rench was brand new. do you think that arp head studs would help because they torgue down to like 75fp. just wondering if this has happened to anyone else thanks.

 

Did you check the head for warpage? Were the decks of the head and block both clean and not scratched? I have to ask, did you use a new head gasket? Did you torque the head bolts in the order prescribed in the manual?

 

is there a dowel there. If so make sure its letting the head seat all the way. Sometimes after milling the dowel is just a lil long and it holds the head up. Also check your head gasket and block. The problem might be in the block.

 

Did you put the headgasket on correctly? If you put it on backwards, it'll leak oil right from the start. I've seen this happen before. Also make sure that the galley plugs on the time gear side of the head are sealed and torqued to specs. Machine shops tend to leave those bad boys loose

 

yes the head gasket is brand new and i put it on the right way and everything i have dal pins in and the surface was super clean and the i milled the head so it wasnt worped, and i torgue it all in the right order right out of the book 22ft and the 63ft i dont know but i have heard when you are running higher compression because i am running 12.1 you should run like arp head studs

 

That's not gonna cause the oil leak right from the getgo......have u checked all of the plugs in the head and made sure they are properly sealed and torqued? Make sure u have the correct headgasket for the application.
