I'd suggest get a set of the little copper washers to keep fluid from seeping out of the bolt holes. It's looking mighty good...don't skimp now.
Very nice... looks like a few I have powder coated, though I have only done 9 inches and 12 bolt GM's.
...if you use that ...gasket...it will ...leak... (clear GE sillycone). did you...powdercoat the gasket surface??? ...:Handshake...
I was asking about the plate gaskets, if I should gasket them... The ends were powder coated but the pumpkin surface was not. I will probobly do the clear sillycone . Thanks...
I have found that gear lube will disolve most silicone RTV. I like to use a gasket (where available) and a thin film (.010") of Loctite Gasket Maker. It swells as it hardens and will hold the gasket in place rather than acting like a lube like RTV does. Clean up is easy because it peals off with the gasket leaving a clean surface for the new gasket. I never use silicone on transmissions or differentials. Some people have good luck with it but I can never get it to hold a seal where gear lube or ATF is the lubricant. Silicone also requires a clean, dry, and slightly rough surface to seal - any oil on the flange will keep it from sealing. Gasket Maker will seal through oil, anti-freeze, and some dirt. Coat both sides of the gasket and install it. It takes very little - just a .010" film is more than enough.
i used ...gasket and crush washers(PITA)...on the first 3 pumpkins i installed...all 3 leaked... my ...differential...guy suggested ...clear GE sillycone. no leaks in the last 2 diff. changes... he puts it on all his...differentials and transfer cases... in all 4 W/D and rock crawlers he builds.he also puts it on motor builds...oilpan...T/C...and valve covers.(none.. on auto. trans.) ......
That clear GE silicone is some very tough stuff. At my dad's suggestion, I used in in place of a exhaust manifold gasket on my '69.5 and then drove the car daily for over a month, which included weekend trips out of state that were sometimes over 600 miles in a single weekend. It never blew out. I also used it (in conjunction with a gasket) to seal the water pump and valve cover. That stuff is 10 times better better then any RTV gasket maker crap you can buy, and you can buy a whole tube of it for a caulking gun for about the same price as a little tube of RTV.
