David, we are talking about the back lifter cover rather than the back of the front lifter cover. Someone in the past deicide to have the return pipe of your oil filter deposit back in through the lifer cover which is not usually the way its done, but they did it. Its not a problem but as I said before, don't confuse that with the crankcase ventilation system.  Tom is saying that on his cars he has a fitting in the rear lifter cover for the air cleaner pipe. I did not on my Cadillac, it came from the ''T' fitting.   If you do not have a fitting in the back cover you can either make one or connect it to the 'T' fitting in the manifold.

Thank you 49er! Those help a lot, You also help me with a post I had a few months ago about two cables that came from the firewall, I can see the one connected to the carburetor. I am not sure about the other one yet. I just got to find where that tube goes that you fabricated on your car

David,  I took a couple of pictures of my spare 38 engine which show the two vent pipes installed on the engine.  On the rear vent pipe I added a PCV valve, just to be on the safe side, and shortened the bottom end of the tube accordingly.

Thanks, Tom, and 49er!

I am going to remove that oil filter canister and installed that tube for the air filter assembly. so that will take care of that. The pictures help tremendously

DAVID E

also is there supposed to be oil in the air filter container?

Tom Beaver

David,  The oil filters from the factory were all oil bath.  In my experience they are both a mess and a royal pain to service.  I would recommend replacing the entire oil bath assembly with a modern paper element (Fram # CA 148). The only original parts still used are the outer oil bath housing and the top (that connects to the carburetor).  It does not alter anything and you could always put the oil bath assembly back in if you wanted to show the car.

I'm late responding on this but on the V-16 the orifice is in the fitting.  It is also a tee fitting with the unused port plugged.  Since the V-16 had dual carbs the port on the bottom of each intake manifold (under the carb) is brought to a central location and then after connecting with a conventional tee is brought to the fitting with the 0.090 hole which in turn is screwed into a tower on the valley cover.  Quite different from the V-8 but functionally identical.

Even more confusing then Brad because if the orifice is in the fitting I definitely didn't miss a small opening into the cast manifold, that was definitely never drilled out.     I may had had something in the fitting I don't recall. Be interesting to see what's on my latest 38 but I'm unlikely to remove it just to look ;D
