Ok so I'm cleaning up my pistons, I just need to know if these are the only oil ports:


... Or if these are oil ports as well (the little hole/indentation in the oil ring groove above the wristpin):

The ports in the top picture are all open, on both sides of all four pistons. The other ones are all blocked, if they're even ports at all. So if anyone knows off-hand, I'd love to have this cleared up before I assemble the engine!

they all are, they all need to be cleaned out

Awesome, that's just what I needed to know. Gonna be a pain to clean out, but I'll deal.
