I always use the black tar stuff with the brush in the cap.It's made by Permatex I think. And you can go to a plumbing supply house and they sell these large white crayon looking sticks that you just scrub on the threads before you install the bools/studs..

I've used both Permatex Indian Head sealant and the equivalent ARP version. Both worked great but you are not going to save the head gasket if the Indian Head sealant gets on the surface of the gasket, and Cometic's aren't cheap.

I vividly remember cleaning up the threads of the block that was in a car I bought that had used permatex (#2 I think). What a PITA, and I assume right stuff would be the same, although do the job, just a ***** to clean up. When it went back together I used plumbers silicone paste, which is used in steam fittings, and all was well.

I spent 7 years working on steam sterilizers, that all I used, nothing will leak past this stuff. I use it on the rocker stand bolts that go into the intake port on my current engine and also any water or oil fittings

I have used the black Permatex tar looking stuff. It worked well but what a mess.

"Dunning-Kruger Effect"
-a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

Indian Head Shellac or Permatex # 2

Messy but seals very well.

I could never get Teflon thread sealers to work, Permatex #2 for me every time now.


Most important, keep the shiny side up

A wire wheel cleans bolts/studs easily..

Lacquer thinner is your friend also to clean things as well as your hands....

Silicone is a poor choice and always has been. It was never meant as a thread sealer....period.

Ends up in the oil pan and oil pump pickup when you use tons of it

Ultra gray is on another level from conventional silicone.
