Pan rust

Just did an oil change on my VG33 this morning. My oil pan is really rusted at the seams. Has anyone ever seen one of these actually rust apart? Thinking I should replace it before catastrophe occurs.

I assume it's a ***** to replace like everything else on the truck right, like the bar that crosses underneath has to be removed? Any other gotchas?

Yes, very familiar with POR-15; been using it on mower decks for years.

Funny timing, as I just started the process of POR-15-ing my truck's frame. This past weekend I did from the rear axle back.

I'd thought of doing my oil pan but I'm almost afraid of scraping too hard. It's the welds that join the two pieces where the rust is, mostly.
I've been thinking about using it on my axle back, the spare tire area is pretty rusted.. did you pull off your bed?

No, I did not pull the bed. I was able to get very good coverage without removing it. Not too worried about the top of the frame rails or the small contact areas where the bed meets the frame.

I might suggest using a smaller, softer brush (brass bristles?) from harbor freight and brush the welds by hand if it's looking pretty bad. Loctite metal epoxy might do the trick for reinforcing the weakest areas before painting. I've seen online where people have used that stuff to repair cracks in the pan.

I dropped the spare and was able to get to a lot of trouble spots. I slathered the spare wheel chain with grease too in hopes of preventing it from seizing like on my old Toyota.
Great idea on the metal epoxy, I'll give that a shot. Same for the brushes, thank you.
