318 Oil Pan Gasket/Sealing techniques?
Don’t use silicone on a gasket. It makes them too slick.
Get some Gasgacinch. Apply a THIN coat on both sides of the gasket and the block and pan rails.
Let it sit for 10-15 minutes and bolt it together.
You can (and should) use silicone at the corners of the pan.
Anything slick like silicone has no business being on a gasket.
Plus, Gasgacinch allows you to get the pieces apart without using chisels and 5 pound hammers to get **** apart.
Someone doing that needs their *** kicked for doing it.
