Re: Head gasket sealer
Unless the gasket is imprinted with sealer on it then a couple of coats of silver or copper spray paint is as good a sealer as you can get. I spray the gasket with a light first coat - let it set - then give it a heavy coating. Do both sides and then torque it down in stages of 10-15 ft. lb. increments.
Here is the process I use when torquing heads or intakes:
My torque process is lengthy and complex but I never have to re-torque nor do I have trouble with leaks or blow-outs.
Tighten all the bolts in sequence (from the middle out) to 30 ft lbs.
back them all off in sequence completely.
Torque them in sequence to 20 ft lbs - going back to the first ones and redoing all of them beforegoing on to the next bolt. (1, 2, 1, 2, 3, 1, 2, 3, 4, 1, 2, 3, 4, 5, and so on)
when you have all the bolts to 20 then follow the same proceedure torqueing them to 35 ft lbs, 50 ft lbs, and 70 ft lbs.
You should be able to go over all the bolts and not have any turn at all with your last setting.
