There are two styles out there; one from Jegs that only works with rigid rail pans, and one from Summit that will work with all pans, including the factory stamped steel ones. I actually just ordered the Summit style. They recommend RTV applied sparingly at the two gaps at the front and rear, struck down and allowed to cure, and the tray installed DRY. Take your time and clean the mating surface thoroughly (scrape, brakleen, etc). I wouldn’t try to torque the bolts to the factory number.
Good to see that they are finally acknowledging what some of us already knew
"This gasket works best with smooth rail oil pans. Dimpled oil pan rail may leak without silicone sealant."
I kept asking , why would you put silicone or any type of sealant on a rubber o-ring molded type gasket ?
Anyways this didn’t work on my 402 Oil Pan many moons ago
Mancini started selling these years ago already
On the Jegs website , I even see Mr Gasket has there own
The Summit Racing doesn’t look any different then the other two that Jegs has listed ?
I still run the factory windage tray , two superformance gaskets dry , and my 402 Oil Pan has been leak free for years
