I don't think I've ever heard of an oil pan rusting through. Over 30 years of snowplowing in Connecticut. I know people who've replaced oil pans, usually do to damage like 4x4'ing in the woods.

Is this a Dodge/Ram thing?

(yep, I went there!!)

Nope.

Happening on my 6.0L. If I hadn't greased the heck out of it it would be gone by now. Lots of video's on youtube of doing the job of R&R.

As a note I have a 20 YO F150 and the pan is absolutely fine. Not sure if having a 4x4 put the pan at more of an angle to catch more of the road spray on the F350.

The differential cover on my 06 Silverado rusted to the point that lube was seeping out. Didn't really lose any, just looked wet all the time.

I’ve heard of it moreso with Cummins engines but I’m sure others are just as susceptible.
Another strange one, Buddy has a mid 2000s Chevy 3/4 ton. Sees a lot of salt and mag driving I-90 pass here in the winter. The rear diff housing rusted clean through and was leaking.
Had to be a thin spot in the casting as the truck isn’t rusted out and even though the mountains are like living in the rust belt, if you drive to the wet side of WA regularly, you get a complimentary fresh water undercarriage wash almost daily all winter!

The axle tubes are .500" thick and the casting is double that in places.

Far more likely the sheetmetal cover rusted through, not an inch of cast iron or the steel axle tubes.

What about body undercoating? This is what I thought it was designed for?

In a boat I previously owned, I had a water leak and salt water reached the bottom of the pan. The following year, it started leaking oil out of one of the various rust spots that developed on the bottom of it. Boat was only 12 years old at the time. Engine was a 5.0L Chevy.

An oil pan will radiate some heat and cool the oil a bit, spraying on a thick insulating material will stop that cooling.

Even in the saltiest of environments, it takes many decades to rust an oil pan out from the outside in. I'd tell him to not worry about it. If I was really that concerned, I'd probably clean and paint the oil pan before I'd put some kind of coating on it that'd just hold more moisture and salt.


Try living in NY State or Ontario Cda with a steel oil pan. Can take less than 10 years to rot it out.


I was about to type the same thing. Here in PA. a friend of mine, who owns a small fleet of pickups, was furious when his first Superduty needed a new pan. It was nowhere near a decade old, and one heck of a bill.
