Rear Cover Sealing - More RTV!
Posted by: vairmech ()
Date: January 07, 2018 04:55PM

The rear cover has always been a pain in the yeeaah. I have put them on and in a car with no problems but if you have to take off the engine mount with the 4 nuts and then put that back on I have had more leaks start that way than I can count. I have also had a few where they just leaked around the bottom. I don't like using RTV around all the oil passages that is in the rear cover but I wanted to stop the leaks. What you see is not lot of RTV but a thin bead that has been smoothed with my finger so there is no excess.

This one is really simple, I only put RTV on the lower half of the outside gasket area since that is the only place I have ever had an issue. What you see in the picture is all I do. I do tighten all of the bolts that hold the rear cover on but I DO NOT put the rear mount on with the 4 nuts. Again I will install the mount, skid pad and tighten the nuts in the morning.

I have this job coming up. Probably will replace the seal as well. I like using Right Stuff in areas that don't come in contact with gas.

I never use RTV and never have leaks there.

Sounds like a deal. All new car manufacturers use gasket maker with NO other gasket material, not to mention SBC intake manifolds.

Everyone keep in mind I am not promoting the use of RTV but rather the correct way to use it and NOT like I have shown in my post of Here Is Your Daily Funny

If you have other methods and/or materials that work, use them. If you don't use anything to help the gaskets that is fine also.

That isn't true at all. There are select manufacturers that do that and with specific items. Chrysler, Toyota, Nissan and several others are known to do that on oil pans. But most still use gaskets on intakes, timing covers, valve covers, etc.
