Hmmm. OK, correct me if I'm wrong, but isn't this the same question you asked before, just worded differently?[img]/wwwthreads_images/icons/smile.gif[/img] That's OK, I understand that you just want to get your facts straight before you dive into this. This is cut and paste from my response to your last post-

I don't know if it's really expected, but it isn't really unexpected. As for gaskets, generally I just use RTV on my diff covers. Lay down a nice bead on the pig, let it sit for 10 minutes or so to "skin", then bolt the cover on. Make sure the old gasket is completely scraped off and clean both surfaces so they're free of oil before putting the RTV on. Also, make little circles around the bolt holes to make sure they it doesn't leak around them, and DON"T OVERTIGHTEN THE BOLTS. They're just holding the cover on, they don't need to be ultra tight, if they are it can cause the cover to warp and leak. Tighten the bolts down like you do lugnuts, that is, don't go in a circle around the diff, snug one, cross over to the opposite bolt, go back to the bolt next to the first bolt etc, etc. After they're all snugged up, then go back and tighten them. Yikes, that was a $10 answer to a $1 question!
I stand by this, I've installed many diff covers with this method and have never had a leak. This is also the method that the rearend shop I go to uses. The only time I have ever had a gasket installed on a rearend cover was done by the dealer on my Z28, and guess what? It leaked. I replaced the gasket with RTV, and no more leaks! It's important to follow the method above, especially the meticulous cleaning and allowing the RTV to "skin".
Hope this helps.
