Last night, we were discussing a different topic and I got shade thrown pretty well over me suggesting "Oil flows through a head." In typical BITOG previous fashion, this was dwelled on. I was able to diffuse the situation, but now, I would like to review how oil flows through various heads.
Many different engines out there. When I see a block, I see Oil Return Passages. So this must mean that the oil comes back down.. Has to, otherwise it would stay up there forever. So, it doesn't travel up the whole head or side of through maybe some kind of pressurized channel, it just gets splashed up there from the upward movement of the piston?
Then I suggested the Oil Return Holes that are directly in.. I said the piston, maybe PimTac took offense to that. Perhaps I should have stated the Connecting Rod underneath the piston. The piston is that moves up and down and has the oil control rings in it, I think there are three ? But I distinctly remember it being said that there is a long shaft that goes up/down through the apparatus under it, that helps oil flow.. So, perhaps that is the connecting rod, and not necessarily the piston (although it all moves up and down as one unit. Thank you, PimTac.)
Can't get enough lubricating, so. Are the holes I speak of in the part under the piston? And are there ANY engines that get pressurized and not splashed oil in the head?
Perhaps from 13:19 on in this video. Would make sense... Oil would drain back down through the center of the big long connecting rod under the piston and provide oil lubrication to that bearing at the bottom.
