4.7 oil pan rust
I got the rust....don't know how bad yet, but don't want to do too much poking/prodding till I am ready with a solution.
I was thinking of getting some thin aluminum, and shaping it so it surrounds the problem area, kind of like a partial pan over the original pan. The rust is mostly on the leading edge and bottom. I would then coat the entire inside of the aluminum with a high temp JB Weld or similar product, and push them together.
I know this would stop any potential leak, and probly last for a few years.
BUT my main concern is about heat retention and dissipation if I do this. Does there appear to be any issues with this solution?
