Injector Cup Sealant
So I have called Ford and they say threadlock 620. What is the permatex equivalent to that? I need it to install injector cups in a 7.3

Loctite 620 is the right stuff. Fastenal carries it.

Isn't the green Loctite recommended if you plan on using ELC?

Loctite 620 is green. It's for high heat applications

There was a thread a while back on which kind of locktight was good to use with ELC, others sealants will be compromise by the ELC.
