Bottom end of a Honda F22A1 ('91 Accord)
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.
Another non car guy here (although I take pride in the fct that I change brakes and oil myself), what's that thing in the middle that looks like the dace of a sad frog?
That is the oil pick up. So with the oil pan on, that pick up sucks oil up to be run through the engine.
Oil pickup. It takes the oil from the pan and delivers it through the engine via an oil pump. Honestly it looks like the screen has some metal debris. And depending on the mileage, could be a little concerning.
I did notice that as well and fished the stuff out with a pick. I only found one magnetic sliver, the rest looked like lazy gasket maker chunks and some pine needles or something that must have fallen in the oil fill cap at some point in the car's history.
There is some known damage to cylinder 3 in this engine due to some idiot leaving a broken spark plug ground strap in it. but it only lost about 8psi of compression so this metal/debris isn't from that.
I know nothing about cars.
How is this different from any other car?
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.
Thanks for the info!
Thank you! Very interesting
That's cool, I've never seen separate oil passages like that either.
They don’t screw around. The H22 has piston squirters too.
They really don't. Good reason these things last forever.
If this engine for whatever reason kicks the bucket, an H22 with a slight bore over, bumped up compression, and more aggressive cam was going to be my drop-in. Plus a manual swap. That plus good manifold design can easily get 40hp or more over what the pedestrian F22 can and would really wake this car up.
But it's my college daily so I can't be doing any fucking with it right now... it runs mint anyway so no reason to.
