2F Rear Oil Leak

[Salt Spring FJ]

My 78 FJ45 has an unusual oil leak located near the top of the clutch bell housing driver's side where there is a vertical open slot (picture attached). I am not sure if it is a rear crank seal leak or from another location on the end of the block as it is higher up than where the seal is located. Can anyone please give me some information before I remove the engine and/or transmission. Thanks.

oil leak

check the back side of the valve cover

It might be the cam plug (at the 2 O'clock position) or the main oil galley plug (at the 11 O'clock)
Just sayin'

RMS

I think you can get to all that with the clutch, flywheel, and oil pan removed without pulling the engine. I only know about the RMS for sure since that is what I just did---here's some pics if that helps

Actually, neither is accessible with the bellhousing on.

bummer

Bummer, can you even see them to see where the leak is coming from?

I think if it was the rear main he'd probably see it down the backside

my 2f only had a little streak down the back of the oil pan
