3 Hondas
Just hooked 'em up today. The one on the right is starting to burn oil, so I don't think it has much time left. Anyway, hooking up 3 is no different from 2, although you tell that to the guy at th...

I just pulled up a random serial number 2000 and it does have a breather hose. It should go from the crankcase to the air filter housing.
Also, see part number 8 in this parts diagram?
That part is a thin reed type plate that covers a hole in the crankcase. It is backed up by a thicker bent plate number 9. It allows pressure to escape from the crankcase and yet within the breather chamber there is a very small weep hole which lets oil drip back to the crankcase. The pressure can blow past the reed valve yet not suck back past it when the piston is moving up ito the cylinder and causing a negative pressure in the crankcase.
They maintain a slight negative pressure in the crankcase other wise the oil that is flying all over in there will be pushed out wherever it can. It will go past seals or even gaskets or the piston oil control ring will be flooded and not able to scrape it and return it to the crankcase fast enough. The oil control ring has groves and openings in it along with cut outs at the back of the piston groove where the oil can flow to the back of the piston.
I'm also looking at item 2 & 3 which are the valve guides. They show that little round looking thing and I dont know what it is. It makes me wonder if the guide may come with a seal attached. Some engines use various seals o the guides and valves so excess oil doesnt migrate down the valve stem and into the cylinder causing smoking.
Old Ford engines were good for having crumbling umbrella guide seals that would end up in the oil pump suction screen. The first sign of failure was a puff of smoke when firing it up. The bad thing was when you hammer it up to 100 mph or so it would starve the pump and take out the main bearings.
