You would think, with all the oil leaks, that there would be no problems with rust...

diesel4me said:Yes,you would assume an oil pan would be the last thing to rust out on your truck--but here in new england acid rain climate even oil doesnt stop rust for long--the salt we dump on our icy roads is like battery acid too --I had to replace the pan on the 86 305 I put in one of my trucks,and the 74 K20 doesn't need a drain plug anymore,since it leaks out by itself!--looks like it was under the bottom of the ocean with barnacles growing on it for a hundred years--and oil is oozing out of its "pores"--more than one pan I tried to loosen the drain plug on tore the "bung" right out of the pan it was so thin!..its simply amazing (and very depressing) too see how fast things rot away here....![]()

That was preventing me from getting a good bite on the bolt head. I trimmed that away with a chisel and utility knife. Once that was cleared I used a 13/16 spark plug socket to remove the bolt. I'll be replacing the drain plug and gasket with the proper parts so this doesn't happen again.
