? did oil enter the pan or just rust it out-quick check on dipstick. Depending on space, the pan might be able to be removed and replaced without pulling the engine
. If it cannot be removed completely, I might even try dropping the pan, cleaning
it well inside and out and JB Weld-ing it if it is good except for a single
spot. The oil pump hangs all the way down near to the bottom of the pan, so that is how far it needs to move to pull it.
