Oil pan and rust

[proteegolf]

One big complaint I have with Navistar is that they used a cheapo thin stamped steel oil pan on a motor that costs well over $6,000 for a rebuilt.

Since these trucks are all 4wd for the most part and used in bad weather conditions with road salt, rain, snow, ice, etc.... One would think they would have had the brains to make a thicker pan, aluminum pan with a 2 piece sump, or a stainless steel pan. Mine was starting to rust in several places. Changing a pan in those trucks looks like a 20 hour job since the motor has to come out. What I did on mine was scrape the rust with a sharp chisel, wire brush everywhere I could, and then clean the pan with brake kleen and 409. I then sprayed the entire pan twice with Rust Oleum brown anti rust primer and let it dry while we were working on the ball joints. I then painted the pan with 2 coats of engine enamel. (Of course the oil filter was removed for all of this). 2 cans of paint cost 10 bucks. A new engine or a new pan is expensive. Cheers.

Yeah, I was noticing mine when I did my oil change last week... Once it gets warmer I'll get under there with the dremel and some sand paper and prime/paint mine as wel, what a PIA.

Yeah mines got a spot about the size of a nickle that looks pitted pretty bad. The rest is ok.

The pitting has me nervous cause thats usually how these leaks start

I put a new oil pan on mine and used about 2 cans of rubberized undercoat on it lol.

I guess I'll pull the engine when she starts to leak. If I do though, I'm replacing everything while its out...new clutch, turbo, sticks..everything. Shes goin back in makin more power than she did when she came out

You MIGHT be able to undo the motor mounts, lift the motor up as far as possible and unbolt the pan. It could possibly be enough room to get it out of there, not sure. Or cut the cross member out and weld it back in or drill holes in it and bolt it back in.
