It has a huge oil leak. It is a '60 Falcon with a small block Chevy. It has a cheapie finned aluminum oil pan. When I started it oil ran out of the bolt holes, not the gasket or seals. I removed a few bolts at a time and cleaned inside with carb cleaner and air. I squirted silicone sealer in the holes and put the bolts back in. The next day I started it again and three bolts still leaked so I repeated the procedure on those three again. The next day those same three still leaked, not just a drip but almost a steady stream. Today I dropped the oil pan to see what I could see. Everything liked right. Gasket was all in place compressed around all bolt holes like it should. It loos like those holes don't even break thru to the inside of the block. The inside of the pan looked right also. What could be causing the oil to be leaking around the bolts? Help Please! thank you.
