8 bad rockers and pushrods. Oil galleries clogged in the pushrods with yellow ooze.

When my push rods were taken out, the area the crack was in that push rod was black!

Tagging this thread.

Do you guys think the busted pushrods were caused by running the motor with antifreeze present in the oil?
