Cheap, and quality plus availability ?

This is the same stuff I have been removing from my 7.3L T444E Powerstroke. I had wondered what that awesome RTV was, and Riffraff had it. So far I have used it in all places originally used when re-installing the oil pan. I will also be using it on the HIgh Pressure Oil Pump (HPOP) reservoir and anyplace else it's needed. This stuff is awesome.

I might add that I only apply it to clean surfaces that have been final-prepped with Acetone. So far, so good.

perfect works great

If you're working on these engines this is the best RTV for them!

Worked great, seemed to seal up flawlessly

This is the only sealant that should be used on a Powerstroke!!
