Hi ! Head gasket job in process here. i attached back the cylinder head with the head bolts….I used permeate optimum red because that’s what the guy at the car parts suggested and it does high temps. But now in googling im finding that maybe it should have been ultra black. Opinions: worth taking out everything and restarting from scratch just to change seal packing? Or just continue and don’t use this seal packing anywhere else (timing chain cover and camshaft housing)? Keeping fingers crossed that it’s not that big a deal
This stuff right? https://www.permatex.com/products/gasketing/red-gasket-makers/permatex-optimum-easy-disassembly-red-rtv-silicone-gasket-maker-3-oz/?location=280%20Schoolhouse%20St,%20Coquitlam,%20BC%20V3K%206V7,%20Canada&category=936&radius=10 don’t see mention of oil resistance.
Usually you use import gray on imports sports and imports but all of that crap is about very similar I wouldn't worry myself too much about it because of the color You're not all of a sudden going to have leaks you didn't have before It's letting the stuff skin and assembling properly is what makes or break an FIPG job.
FIPG seal is really good and we cannot find anything aftermarket as good as original FIPG Toyota. But we must make sure that the surface is completely clean and dry. Use isopropanol or brake cleaner before applying any seals.
