I got a gsr with b16 head spoon 2 layer gasket and arp headstuds

i followed the directions and hand tightened the studs into the block

then i put the head on and torqued the head down to 75 lbs doing increments of 10 each time in a star pattern....i followed the pattern by the book.

now i noticed my headgasket is leaking slightly anyone know wat might cause this?

o btw the whole motor has bout 400 miles on it brand new everything

does it just need to be retorqued after breakin period?

 

Use copper spray on the gasket it'll seal better. Peace.

good, its supposed to be 85

but it could also be a variety of things

did you reinstall the coolant studs

how about milling and or resurfacing the head

it wasnt supposed to be in a star pattern it was supposed to be on a head bolt pattern

out side in

 

coolant studs? i resurfaced the head before hand

and yes its star pattern arp head studs the studs tightened by hand

so its 85 with 2 layer gasket?

 

still leakin

 

Evertime I have assembled a motor I torque the studs to 75 lbs. I think the coolant studs he may be talking about are the dowel pins. They actually run oil not coolant.

 

You could try upping the torque on the head studs. One of my motors had a slight head leak with ARPs, so I upped the torque to about 85 ftlbs and that solved the problem. (Leak presented itself as coolant temp spike under full throttle, but block test didn't confirm anything)

second, it sounds like you followed the correct pattern for torquing the studs. (start in the middle, criss-cross your way to the ends.)

 

i didnt replace the dowel pins didnt tihnk i had to

i will retorque them when i do my cams ima put assembly luve on the nuts as well

 

when you had the head surfaced did you make sure that the head and the block are even and not warped? And yes copper spray is good...

 

i had the block inspected the shop said it was fine i just got th ehead resurfaced

 

when i do my cams ima retorque the head to bout 85 + lbs
