Beautifying the oil pan-948 rebld. It's the pits!

Well, dropped off the crank, block, cam and flywheel at the shop for some reburbishing and now I have staring at me, an old oil pan.

I've never seen an oil pan so pitted on the bottom. Is this common (dents, yes, but pitting - and under the paint (which appears to be original (green with an orange/brown primer))?

Anyway, I want to clean it up a little. I thought wirebrushing and then filler and paint might be sufficient- but then I wondered if it wouldn't be better to use something like JB Weld, spread on like filler, to do it. Would it be better suited to all the rocking and rolling and shaking?

Any suggestions?

Thanks,

BillW
 
Doc would recommend Lab Metal.
 
I have 2 948s that I just got with my 71 Midget purchase. (and 3 1275s)If I can not sell them whole then I'll part them or take the 948s to the scrapper as they are. These parts need to find a new home soon! $50 will get a 948 from valve cover to the pan! Bob
 
On an oil pan, the only 'cosmetics' I'd do would be to whack out any dents with wood drifts, be certain the lip mates true to the block (bolt holes and surrounding metal should be flat), paint it proper color and that's it. If there's internal corrosion/pits they need to be 'investigated' to be certain they aren't going to turn into pinholes any time soon.

Inside is smooth as a baby's bottom. External is loaded with pits and a few scrapes. No dents, oddly enough.
 
It's designed that way from the factory. The pits increase the surface area of the pan to enhance oil cooling--their seemingly random positioning is to ensure non-laminar airflow. :jester:

Nice. Geez - I was almost convinced to leave the pitting alone!!! :smile:
 
What Doc said, I dolly out dents on the the bottom of the oil pans. The bigger chore is getting them cleaned and stripped of paint, I take all engine sheetmetal down to bare metal, it take alot of effort, once degreased, then paint strippers, and then bead blasting.
 
You think that's bad, I still haven't found a good way to get oil back up in the hole to refill. Everytime I squirt some up there, it comes right back out. :wall: :crazyeyes:
 
You could get a 4 ounce can of the silver por-15. Its made to self level and fill little holes and then be top coated slick as a whistle. Its used in rusted floor pans and things after you wire brush them. It will even fill little holes of 1/8" or so and make it rock solid and not rust any more and hold up to anything then.
