head bolt lube

andydap · Jul 18, 2023

hi again, this time what do you think is the best lubricant to torque down head bolts? and if its not just oil, where can i get it?

Right or wrong I give them a dab of oil

I used oil for years but now use ARP hi torque fastener lube, it s good stuff

I second the choice of ARP lube. I did some tests of different lubes and the ARP lube will gain you between 5 and 10 percent clamping force with the same torque wrench setting.

Just curious, do any of the head bolts go into the water jacket? I know some automotive engines require sealant.

hi, no, not that i can see but i had a comment from someone else who suggested to use a sealant on the right side of the head where all the coolant openings are. he said to run a bead above and under the gasket around each opening. he gave the name of the product but i forgot and didn't right it down. any ideas?
