Howdy all,

I'm in the process of reassembling my F engine. I took pictures of the engine as I disassembled it to make the reassembly go more smoothly, but I seem to be missing a few.

Attached is a picture I just took of where the oil pump tube attaches to the block. Am I missing something that should be screwed into the hole to the right of where the tube attaches to the block?

Thanks for you help!

Please help.

This is the last thing I need in order to be able to put the oil pan back on. I've looked through every picture I can find on mud. All the pics seem to be of 2F's. It looks like on the 2F they filled in these two bolt holes.
It's been a while since I've looked, but I think that's supposed to be an empty hole...
Since the "F" engine is a bypass flow and uses and external filter and regulator, that is the return port from the filter/regulator.
