Cleaning Oil Pan and Sump

[deathkeeper]

I am doing a full timing chain job, and just got the oil pan and pickup off yesterday. The area where the oil pickup sits had lots of chain guide bits (both plastic and metal) in it. There was hardly anything blocking the oil pickup itself. The pan was coated in a layer of fairly thick sludge. I washed all of the bits of chain guide out , and filled the pan up with gas to dissolve the sludge. After an hour I dumped the gas out and let any remaining evaportate overnight.

This morning all of the sludge was gone and the pan was clean enough to eat off of, but much of it has now rusted. What should I do to the rust on the inside of the pan? I have a can of naval jelly and duplicolor engine enamel. Can I use this paint on the inside of the pan, or should I just remove the rust and coat it with oil? I really don't want to take a chance of the paint flaking and clogging my oil pickup.

Update-

To repaint it I would have had to sand and flush areas that were impossible to due to the pan baffling, so I just wiped off the surface rust and coated the entire pan with a bottle of Rislone I had laying around. Without oxygen, the rust cannot grow, so I figure it will not with it constantly being coated with oil on the engine. I also covered the pan with plastic wrap to keep out the dust before I reinstall it.

i dont really know what risolone is, but i would also think that it wouldnt rust when there is oil in it

Rislone is just an oil additive about the consistancy of 5w-30. I used it because I did not want to waste any Mobil 1 synthetic.

i got ya. that should work fine, once you have it bolted up again it wont be a problem.
