Just out of curiousity, what would happen if you installed stock head bolts that were stretched beyond spec?

 

They would probably snap, and then you would have to drill it out...

 

Im just curious if it would cause an imperfect torque reading? I torqued a head with 30,xxxkms on it, to a new rebuilt bottom end. Its leaking coolant into the #1,#3,and #4 cylinders. #1 and #4 are really bad.

Both the block and head were decked. But I reused the headbolts and I am wondering if thats my culprit.

 

did you use a new oe spec gasket???

did you spray copper gasket sealer on it??

did you torque in order??

 

dood.. bolts are 10 bucks a pop.. just replace em

 

No I didnt use the copper spray..

I did and will always use a new OEM head gasket.

This is the third time these bolts have been used and it looks like I will be needing a new head gasket and ARP head studs.

 

When in doubt, just replace with new ones......

 

do yourself a favor and get the arp head studs, and use copper spray and make sure the gasket was on the right way

 

how can you tell if the gasket is in the right way, isn't it the work up is suppose to be seen. and where do you spry copper spray thanks
