Question

I am currently in the process of rebuilding my 69 396 motor and I'm about ready to re-assemble. Here are a few questions I have since it's been about 30 years since I put one back together.

What bolts do I need to put anti-sieze on?
What bolts need sealer and what type?
What gaskets need gasket sealer?

I plan on running thread cleanouts on all bolt holes and I have the one piece oil pan gasket. I have steel shim gaskets for the heads that I plan on spraying with copper coat before tightening them down. Any other advice or suggestions would be appreciated!!

Thanks! [img]graemlins/waving.gif[/img]

Put sealer on any bolt that comes in contact with the water jacket, i.e. head bolts, manifold, water pump. Use the blue engine silicone, you'll be able to locate it at your local auto store. Also use the silicone on the corners of the lower timing cover to oilpan gasket, and at the corners of the heads to the rim gaskets as well as the ledge for the intake manifold. You may want to smear a small amount around each of the ports from the intake to the heads.. Just to keep any water from seeping through.

I gotta disagree with the silicone thing. Use a sealer on ALL head bolts, manifold, and water pump. This is correct. DON'T use silicone on these. I use a Permatex product in the can called High Tack. Just dip the threads in the can or brush it on and thread into place. Use high tack on all other fiber gaskets if needed. Use a black silicone in places where gaskets meet, i.e. manifold gasket corners (can use silicone instead of rubber/cork end seals), if not using a one piece oil pan gasket (recommended) use the silicone at the corners where the gasket meets the seals. Silicone has a tendency to ooze out and a small bit can break off in the engine and clog things up (not often, but it does happen). I like the black silicone because it seems to hold up better and resist oil and fuel better. I have used High Tack for over thirty years and never found a reason to change. Use it sparingly as you only want to seal small imperfections, not canyons. Don't smear sealer all over the intake gaskets, just around the water ports (if needed). Just smear one side so the manifold can come off in the future. AutoZone has the High Tack and black silicone. Remember, using less is a good thing. Just enough to get the job done.

Permatex, Indianhead Shellac Gasket Cement on all bolts going through to water. In the shoe polish, dauber bottle.. A little daub will do you fine..

And on the waterpump gaskets and all others but clean up any excess to make her look pretty..

And Black RTV at the corners of the intake and pan..

And right-on about the Copper-Cote for the headgasket..
