I just rebuilt a '77 Scout with a 304 and standard transmission. I've been working some electrical issues but it is overall running pretty well. My question is both of the phillips head screws are leaking at the back of the pan. It seems like a wierd place for a leak. Do I drop the pan and regasket it or do I pull the screws, break clean and silicone them, or is it some kid of pressurization issue?
