leaky diff cover

Well my rear end is leaking out of the diff cover. I'm gonna take it off and clean it up. My questions is do I use a gasket, RTV, or gasket and RTV. Let me know what you guys are using.

Should be gasket and a small bead of RTV on both mating surfaces. The small bead on the differential housing itself will also hold the gasket in place while you install the cover. I usually put the bead down and then smooth it out completely with a clean finger. Just make sure you clean all mating surfaces completely before installing the new gasket etc.

you can use what ever you wish but make sure the cover is flat and not warped at all and there is NO OIL on the area where the seal will be, clean the crap out of it

It would also be a good time to upgrade the cover if you wish. Summit racing sales a really nice cover pretty cheap. It has some benifits to it. Like drain and fill plugs. Some have cap load bolts that are on the more expensive covers. Oh and look bad ***.

I already have a Ford racing cover that is fairly new so I don't think the cover is the problem. Just a bad rtv job from the previous owner
