Bottom end of a Honda F22A1 ('91 Accord) - eviltoast

Clean as a whistle. I love this car to death.

Very interesting how Honda built a separate oil galley casting that bolts to the bottom of the main bearing supports for oiling, rather than run galleys thru the block like most other manufacturers. Probably explains why these engines last so long, having those nice big high-flow passages everywhere.

      See those 3 long cylinder looking things? Those are not normal in many other engines. That’s part of what OP is referring to.

        Yep that’s it. Those tubes carry oil from the oil pump to each of the main & rod bearings along the crankshaft. It’s unusual to see dedicated galleys like this outside of very large displacement industrial motors, most manufacturers just cast small grooves inside their engine blocks to carry oil around the bottom end.
