When installing timing cover, h2o pump/housing

[kaj750]

Engine: Chrysler 440

I know this post is terribly generic, but hoping to gain some insight:

I pulled my engine apart to verify timing. I am currently reinstalling the timing cover, water pump housing, and water pump. I have all of the gaskets. When I took the engine apart there was RTV on everything. Is this necessary, or can I just use the gaskets?

Same with the valley pan (I am also installing new cylinder heads).

Any help would be appreciated. Thank you, very much.

I use some Permatex Hi-Tack on the gaskets. Just a little RTV on the corners of the timing cover down by the oil pan.
Check the balancer for a wear groove. I sand a cross hatch pattern gently on it using 400 grit paper.
When you put the cover on leave the bolts finger tight and roll the engine over to center the cover on the balancer.

Doesn't the 440 have dowl pins in the block for centering? You may or may not have sealing problems at the pan and timing cover if you did not pull the pan. Some do, some don't. Just make sure that area is clean and silicone the joints.

If you didn’t pull the pan I’d RTV the bottom of the timing cover with no gasket. Coat both surfaces. This will allow the cover to install w/o any chance of displacing the gasket. I use Ultra Grey on everything. Why? I hate leaks. If the surfaces are clean and dry it will seal, guaranteed. You don’t need much. Just enough to cover each surface if using a gasket (timing chain cover to block, water pump). Without a gasket (timing chain cover to pan) coat both surfaces, then add a 1/8”-3/16” bead. When it’s dry the next day you can remove the excess (which will be very little with this amount) with your fingernail or small screwdriver. You’ll never even know it was used. Except for the fact it won’t leak. The only reason to even use theses gaskets is it makes it was easier to remove the parts if needed later.

Installing a new pan/gasket. Not taking any chances.
