Howdy. I'm soon about to replace a few gaskets on my LN3, including the oil pan and front/timing cover. If I have the surfaces clean and free of solvents (I use Total Prep to clean that kind of stuff), do I need to use RTV or something on the gaskets, or install them as they are?
Thanks guys. I search and couldnt find a good answer.

Total Prep? Any oils?
Gasket surfaces are typically expecting a dry install on our cars. The only thing I can think of that would want some RTV is the corners of the LIM gaskets where the heads meet the block.

Total Prep is intended for preparing automotive surfaces for paint, so it doesnt leave any residue or anything. Its strong stuff which is why it suggests to wipe with water afterward.
Ah yes, I do remember using RTV on the LIM corners.
But thank you Bill. My question is answered...install gaskets as they are.
