Good afternoon.
I have a '55-'57 model 261 in my '53 1/2 ton, rebuilt last year, and ever since has had a pretty decent oil leak. This weekend, in an attempt to locate the leak, I cleaned the entire underside of the engine with simple green. While doing so, I noticed a very small pin-point size black dot that would re-appear when I would wipe over the area; about 2" from the oil pan drain plug. So I let it sit and after about 2 minutes, it accumulated enough oil to form a drip, and dropped. It's seeping through the pan!
So, my short term solution is to drain the oil, scuff the paint off that spot, and spread JB Weld, and re-paint after a day or two. I think, given that this pan is obviously corroded, I need to find a good replacement. (hopefully this provides a fix, and my fears of a rear main seal leak were inaccurate)
Question: Are all oil pans on 216/235/261 engines the same? If no, how do I know which one I have/need?
