crazy3dgen,
There should have been 2 small holes inthe side of the piston to lubricate that exhaust bridge you see with the pipe off, and yes, the hole would be hidden behind the exhaust bridge. I was just asking to make sure you didn't see the big rectangle hole that is supposed to be facing the intake side (no way for that exhaust bridge to hide that hole). The arrow points to the exhaust side of the piston with the two small holes.
