 Re: head bolts

Its best if you have a inch pound torque wrench to use. I torque the nuts to a max of 110 to 120 inch lbs. When I've taken the head off I use aluminum spray paint to coat the head gasket on both sides this will act like a gasket sealer. Torque the nuts in a cross pattern start at 40 in. lbs. then go to 80 in.lbs. last I use 110 or 120 in.lbs. if I've had the head off more than once I will go to the higher setting. I watch the gasket area for leaks and if I find it leaking then I make a new gasket as the old aluminum leaks pretty easy once its been messed with. I use a special high temp gasket material for the head and exhaust gaskets and it bumps up the compression a little as its a little thinner than stock. My homemade ones have yet to leak. I'll have to get the name off the material if your interested. Most industrial gasket shops will carry this stuff and there is lots of scraps that you can get. For a lot less than you would pay for in a parts store. |
