HG replacement -cam carrier RTV

Last link in my signature is the full engine section from repair manual, hopefully addresses it. I would download if possible. On a phone turn it landscape to see signatures.

 

Looked through that, spec on page 11:



I believe this is where Gasket Masters sub'd Permatex Ultra-Black. More readily available, and much more leisurely cure time I believe.

and on page 12:

 

I like the real-world technique I've seen Gasket Masters use for applying the the liquid gasket, just going along the path putting a dab every 1/2" inch or so, then patting and smearing it uniform. The Repair Manual explanation regarding diameter of the bead makes sense to a draftsman, but seems awkward to execute. With Gasket Masters technique, where Toyota spec's a thicker bead, just tighten up your dab spacing. And when done, look for thin spots, add an extra dab or two.

Again, the permatex ultra-black info says it has a longer cure time, so no need to get it all placed and the item installed within 3 minutes (spec'd by Toyota). One caveat: Toyota says 2 hours before adding oil and test running. I believe Permatex recommends 24 hours.

Full disclosure, I've never had the "pleasure" of doing a head gasket, hopefully never have to.
