General question here, looking for a little direction

I've got a tired '80 12A in my RX-2 and there's quite a bit of blow-by due to side seal wear. The engine has enough blowby pressure to emit oil from the fitting near the Filler tube on the Center Housing that goes up to the air filter. I'd *like* to hook it into the air cleaner since it does draw vacuum and the air gets routed via the PCV valve into the intake manifold, but I can't because there is enough oil blowby to foul the air filter and spew oil into the carb.

I think what I need to do is fabricate some sort of oil/air seperator for that fitting so that it can suck in FILTERED air at idle/cruise but can't spew oil back out when the RPMs get above 4000. Currently, I just have a hose coming off the nipple going down below the engine (similar to the oil draft tube on pre-65 American cars) where it just blows that oil onto the street. This is hardly ideal though, since it is sucking unfiltered air through this hose into the engine. Plus, I have to add oil quite frequently to keep the level right. Guess that's just part of owning a worn engine though . . .

Any tips or thoughts on how to tame the oil flow out that little pipe would be appreciated. Rebuilding is not an option at the moment due to low $$$.

thanks in advance

 

If you can't run it to the carb, get a carb spacer and tap a fitting into it. Route your line that you can't run into the air cleaner into that fitting.

Save up to buy a running motor or a rebuild kit. If its worth fixing, its worht fixing right.

 

well, I'd do that, but that just feeds one more thing into the intake manifold. This fitting is the one that needs fresh filtered air so it can be circulated through the crankcase and *then* sent out the oil filler tube fitting to the PCV Valve and intake manifold to be burned. Sending both lines to the intake manifold would effectively seal off the crankcase from atmosphere pressure, creating sludge and far worse blowby . . . .
