Oil pan maintenance

Post by Sandy »

I did a search on this topic but nothing came up that addressed the problem.
I have removed my oil pan to replace the gasket and found that the inside paint coating is starting to peel. Not wanting this stuff up inside the engine, can anyone suggest a proper paint to recoat the inside of the pan?
While we are on the subject, what is being used out there to paint the outside of the pan?
Cheers,
Sandy

Painting the inside of an oil pan seems strange since oil is a great rust preventative. I would be inclined to strip it completely inside and out. Outside, Rust Bullet is amazing and designed for military ship use. I've used it on my Land Rover frame with terrific results. Regular rust paint can then be used to paint whatever colour you like.

Good luck. Cheers, Clive

Rover had a good suggestion. I can tell you that three years ago when I pulled my pan the interior was not painted or coated with anything but oil that I could tell. I went ahead and painted the exterior black with a black rustoleum spray paint and it has held up well. I generally pressure wash the entire vehicle twice a year and haven't had any issues with the paint pealing. My guess is if you prime it correctly you can put any quality exterior high heat paint and it will hold up well.

Good luck.

Painting internal "oiled" areas is somewhat covered here:
viewtopic.php?f=8&t=8355&start=45
.........but I have put the pertinent part of the post below.
Although I was primarily talking about alloy cases, the same is applicable to ferrous castings etc.

BTW, I zinc plated the 718 sump then powder coated the outside only.....the powdercoater didn't recommend painting the inside.
As regards the interior painting, again I use a product called Glyptal which is specially developed for this use as it:

1/. Stops weeping/permeating through the castings.
2/. Helps with oil drainage.
3/. Seals any stray material/media after blasting etc.
4/. On cast steel components such as the drop boxes it stops internal rusting from vapour/condensation.
