Oil catch can

[papacurdog]

OK my late son disassembled his b18 out of his 1990 integra. I have takin upon my self to give the enitre car a facelift. I am putting the engine back together and have found the oil catch can on the back of the block. There are two holes on the top of this can. My question is what do the connect to?

If there are just two holes in the top of the can then the plastic hose fittings have broken off. (They become very brittle over time. Mine broke and I screwed a brass hose stem fitting into the hole).
Anyway, they are for the PCV system. One hose goes to the PCV valve which then goes to the intake manifold. The other hose takes a sharp 90 deg turn and goes to the side of the block. (Don't mix it up with the fitting that comes out of a 1"+ metal pipe that sends coolant up to the throttle body).
