Might sound like a dumb question but the instructions do not explain it too well.

When using ARP studs for the heads or mains for that matter, you obviouslly have/should put ARP assembly lube on the side that you are putting the nut on, however how important is it to put it on the side you are screwing into the block? Make a difference in the torque reading at all? Or not affected?

 

the bolts that go into water jackets need thread sealent. i would put it on all bolts.

 

I realize that but im talking about the assembly lube for the right torque. Only needed on the side you put the bolt on to get correct readings or need it on the side that you screw in hand tight as well?

 

its a good question, and i dont know if i would be right by saying that if it is harder to turn the stud that is threaded into the block (that should not be turning in the first place) it would not affect the torque reading on what the nut would see. consider if the stud was to bind from friction, the nut would not be binding becuase of the oil, and there are two possible places to turn(the stud and the nut) so you would get a certain amount of clamping force regaurdless if the stud could turn or not. as long as the nut is oiled i could not see a logical reason as to why it would affect the torque reading, considering that on a bolt the head does not turn and this does not affect torque. so no. i would use arp thread sealant w/ teflon on the threaded end that goes into the cylinder case so that the stud would be able to be removed in the future and to protect the thread of the stud and block.

i hope you have made sence of this and it answers your question through application of logic.

 

oh dont forget to oil the washer too
only one side would need to be oiled as the nut only slides along one surface of the washer and it would not need to oiled on the side facing the head, same idea as the stud.

 

The head bolt holes into the block go RIGHT DIRECTLY INTO the water jacket. If you don't use sealer, it WILL leak around the bolts, guaranteed. Studs are bad enough about doing that anyway; in fact I don't think I've ever seen a motor with head studs where they actually sealed. Not using sealer on them would produce 34 absolutely certain water leaks.

They do not have to be "torqued" to any particular value, so assembly lube is the wrong thing to use.

Main studs are a different matter. Those you can use the lube on. But again, you don't "torque" them to a particular value, so it doesn't make a whole lot of difference.

If you haven't already broken the package, I'd strongly recommend you send the head studs back, and get bolts.

 

Thanks guys answers my question. I have ARP assembly lube but am using non arp thread sealant for the bottom part of the head studs and on my outside bolts for my splayed caps (break into the coolant passage). So looks like ill be fine, just wanted to know if i had to pull the studs out because i used regular type thread sealant on the bottom (part that threads into the block) instead of the arp thread sealant. Sounds like it does not matter which is a big , yes i am using arp assembly lube on the top part appreciate the help fellas.
