My local Napa couldn't come up with a gasket for the diff cover for a Dana 80 axle. :confused: They said Victor Reinz didn't make one and that the dealerships just use "the right stuff" silicone to seal the covers.

Anyone have a similar problem with their D80? I know Ford used them too.

I don't use gaskets on things like axles, I just use whatever kind of selant I have around. I know they are starting to do it that way in the factory in some things. If I remimber "the right stuff" is a bit more expensive than other brands and I've never had any leak so I wouldn't spend the extra money.

I agree about using just a sealant in place of a gasket. I have even used it as a valve cover gasket on a 429ci intercepter engine that I had years ago.
I don't want to stael the thread but I see you have a Mack B61 listed in your signature. I helped restore one of those about 20 years back. It had a Quadruplex trans in it instead of the 10 spd. Very nice trucks when they are done up right.:cool:

Just use black RTV and spread a thin layer on both surfaces..let it cure for 10min and then slap on the cover and tighten in a cross pattern like you do with lugnuts.waytogo

Hmm, I have always had back luck trying to make silicone gaskets I guess. I've done valve covers and diff covers, all of which seeped on me. I got some of that fancy "the right stuff" that is supposed to be even better. I guess I'll try out the liquid gasket idea again...:D

ultra black works fine on diff covers. do them like this all the time and no leakers.......

I've used blue, ultra blue, black, and ultra copper with good results.

RJF,

My '95 has the Dana 80 and it came from the factory with sealant, not a gasket.
