Properly sealing timing cover to oil pan.
Watching this thread with interest. I am having the same problem with mine, and in the same area too.I'm trying to seal a bunch of parts (Hughes stud girdle, windage tray and oil pan) but pretty sure my leak is in the same place as OP (corner of timing cover where it meets the block. Already had it all off once, bought a new straight Proform timing cover, put it on with RTV and didn't tighten until balancer in, etc. And it still leaks.
:mad:
