The inside of my oil pan is rusty from sitting empty for many years. How would you fix?
I am considering evaporust (would have to buy several gallons),
por 15 or similar product, or a rust convertor.
What would you choose an why?

I would just have it blasted, get it really clean by wiping with kerosene or acetone then paint the outside put new seals in, then a heavy coat of new engine oil on the inside. Same with the dipper tray

Make sure the rust did not make the pan pores. If it ate away at the original pan metal i would not use it... i guess you wont know till you de-rust

Thanks for the replies. Well this is on another vehicle where the baffles are spot welded in so I do not want to blast with the risk of not being able to get all of the sand out

Agreed, those dipper pans snap in pretty good so there should be no reason to have to weld it in... They seem to be plentiful.

That way when you blast it gets rust and anything else out of the pores, if the sandblasting finds a weak spot its better to know now VS later on when oil seeps out.

I'm thinking you are referring to the dip tray and the three oil baffles spot welded to it. Even this can be sandblasted, and I've done it. When I'm done I used compressed air and tap the baffles with a small hammer as I blast the junction with air. I'll rap the pan several times as I blast to make sure all grit is removed. You can also use Evaporust to do the job.

I also sandblast the oil pan and paint it inside and out, just as Volkswagen does on my diesel Rabbits. Many industrial and marine engines paint the pans and blocks on the inside.
