I swear I posted this somewhere already...but I can't find it.  Anywhoo-

I agree about the Toyota FIPG.  I work at a dealership and its the only stuff I'll use.  Theres some sealing the valve covers on my diesel Ford right now.  Its the best stuff you can get, but its messy and expensive.  I tend to have "extra" after finishing jobs, so I don't usually have to pay for it, but would pay the price even if I didn't work there.

Also, I always use a product called Gold-N-Seal on the timing cover gaskets.  Its basically like oldskool copper coat, but a little better.  IT comes in a rattle can, so you can spray on a nice thin even coat and let it almost dry.  Spray the other side, and let it get tacky, and it holds the gaskets on the block just right until you can bolt down the cover.  It doesn't ooze out all over everywhere and comes apart easily next time the timing cover needs to come off.  I leard this from a 10yr. Master Tech, and between the 2 of us, we've never had one come back leaking...
