I'm with you Frank. Its all I use except in case of MLS gaskets of course. I seldom have leaks. I use grey rtv, rigid. I won't use anything else. I've seen many racers get pushed off the dragstrip by track officials because of oil leaks. I can't afford to drive 7 hours to a race and not be able to get down the track because if my negligence. Up

But hey, to each his own.

I use it too and have done for nearly 30 years on my race engines. Like most things, if it's done right, it's fine.
I'm only old on the outside.

I think Bills point is they actually make sealers for those pucks that is superior to clear silicone bathtub sealer in any quantity....

I'm doing mine soon. Right now I've got almost all of the old paint off the cases so I can paint. The cam is out so after painting....I'm ready to install the pucks. I believe it was Edward Morris that said he used Permatex #2 and had no problems. I planned to remove any excess after leaving it to set up. What about the O-rings at the oil nozzles and the end passages. Should they be left dry or a dab of something to hold them in place? I also picked up a tube of the high temp thread sealer for the tower studs. I will reread Brandon's thread before I dig in.....I've probably read it at least 5 times already!
I just planned on using the #2 instead of the Hylomar sealer unless someone knows of a reason I shouldn't.

Nice example, Bill ;)

I use #2 on the pucks..........nothing on the o-rings or oil-jets.

I have used it too since late 80's (got it free at my job) . Before that GOLDEN HERMETITE that was really good, worked fine sealing cases too.

Put it on both sides of every gasket and you'll never need to buy another gasket. It's like really sticky Vaseline.

Just be careful.  The Hot Cinnamon flavoring is probably good for an extra HP or two, don't you think?  :o

The EZ turn sounds interesting (the gasket one!) but I already have a tube of Permatex 80060 high tack gasket sealant. My plan is to stick it only to the cover side and a light smear of assembly lube to the case side.
I painted my cases yesterday so I'm getting closer to putting things back together. Still have to do some touch up and cover polishing. I don't care anymore about the time consuming task of polishing....it's so worth the effort! Here's a couple of pics.

The EZ Turn seems to be a good thing to have in the garage. Probably useful in many applications.

 I bought a 477" big block chevy that had the blue silicone overhaul kit, the oil pump was even full of it. It can even wreck a big block.
