Saving Old Seagulls

The wist pin is a tube that is closed off at one end.

When I pulled the motor apart the closed side of the wrist pin was pointed to the exhaust port.
When I reassembled the open side was pointed to the exhaust port. (oops...)

Does it matter?

I always fit them closed end up, worried about them filling with oil & getting heavier, but don't recall anything regarding this in any of the Seagull paperwork.

That was my logic in assembling with open end down as well...

Going back through the pictures from when I disassembled I noticed it was open end up.

Thought I would ask.

Thanks,
