Rear main seal lesson

I put a small dab on the end of each seal half and then run a small bead where the seal retainer meets the block. On engines where the seal installs into the rear cap, I do the same, but run a small bead along the block surface to where the machined ledge is next to the ends of the oil pan gasket. This effectively seals the seal ends along with the entire joint where the main cap meets the block. Been doin it that way over forty years and never had a leak on a newly assembled engine. So far.
