Are some or all of the motor mount bolt holes in the side of the block drilled clear through? I keep finding a drip of oil hanging on the curved bottom of the right mount plate and I cant figure out where it’s coming from. I have dye in the oil and nothing is coming down from above - valve cover, intake China wall, distributor, fuel pump, pump rod plug, timing cover, front seal - all dry and no dye. About all I’m left with is possibly oil wicking out a motor mount bolt. Older photo but the darker spot on the bottom is where it’s always showing up.
