I thought my oil pan drain plug was leaking when I discovered a pin hole leak right next to the drain plug. Any body know of a fix for this tiny leak? Hopefully I can repair without taking the pan down.

Re: oil pan pin hole; 1964
I had a leak like this on my old 4x4. What I did was clean the area down to the metal with sand paper. With oil still in the tank you could easily see where the pin hole was. I had a small hot glue gun ready and injected a VERY small amount into the hole to stop the leak. When I was sure that the hole was plugged so that no oil would weap out during my repair I, as Garth suggested used JB Weld over the repair area.Comment

Re: oil pan pin hole; 1964
JB weld or similar two part epoxys are TEMPORARY fixes. Permanent fix is oil pan replacement. in between the two extreme fixes would be brazing or tig welding the pin hole. i'll bet ya a dollar to a donut there are MORE pinholes residing near the leaking one.if the engine in your 64 is the original and there are more pin holes that eventually leak, ya gotta hope they don't spring the big leak 100 miles from home, at 4000 rpms, in which case your original block could be toast.JB ok for temporary fix, per Bubba's Motor Manual. mikeComment

Agree..
As Mike said, my experience is when there's one pin hole adjacent to the oil pan plug, the entire adjacent surface is well worn making it a matter of time before you spring more leaks. I wouldn't be in such a hurry to effect a repair on car... Dropping an oil pan is one of the easiest component removals going!
I'd drain the oil, drop the pan and visually inspect the inside surface. I'll bet you find the corrosion is more wide spread than you might have thought. The pan plug is the lowest point in the pan, a place where water will settle when a pan is left to sit dry.
Brazing the damaged surface is about the best fix short of wholesale replacement of the pan...Comment
