Depending on the gasket material as to what I use. If it's a "solid" material like some of the Garlock gaskets, I usually use something like Copper Coat or Hi-Tack. For the fiberous gaskets I like using Ultra Blue, Ultra Copper, etc. I've always had had good results with them. The good thing is they seal as good or better than straight silicone but they don't tend to ooze out of the joint and harden into pieces that will fall off and contaminate the machine internally. Working on equipment it never ceases to amaze me how much silicone some people will put onto a small piece and never even think about where all of it's gonna go as soon as they tighten the bolts. For cork gaskets, depending on where they are, any of the aformentioned products work good. Now in extreem cases it doesn't matter what type of material you have you can use weather stripping cement. It's a pain in the a-- to clean off old gaskets when you use it but nothing will hold a cork valve cover gasket that keeps "oozing out of place" where it's supposed to be and sealed. Now for places that don't take an actual gasket CAT has a new sealer out there. I don't know who makes it for them but tt smells alot like Locktite. it comes in tube form with about the consistency of other sealers like Ultra blue. I used it recently on a Perkins engine rebuild and it's almost like the parts are glued together when the stuff is set up..but that's the way it origionally was so that's what I went back with. The drawback is it makes the engines a pain in the a-- to tear down because the parts are usually aluminum and it's hard to get them apart without damaging them due to the adhesion of the gasket material. Not to mention that once the parts are apart it's a royal pain to clean the it off of them.
