250 clifford valve cover question

I got a finned valve cover,and a finned air cleaner and installed them.
But I have a question about the PCV hook up.
The old valve cover had 3 holes the new one has one, plus a breather "box" on the right rear of it.
The old valve cover had two breathers on it and a pcv valve on the side going to the the bottom of the air cleaner.
My question is were can I put the pcv valve on the new valve cover and were should I hook it up? I was thinking of a pcv oil filler cap with the pcv hose hooked up to the intake ( a clifford manifold )
Or do I hae to drill the valve cover ?
Is the intake port a good place to attach the pcv? Or is the air cleaner hook up ok ?

I would just put a breather filter in and forget the PCV. Definitely would not drill a hole in the VC. They aren't cheap as I'm sure you know.

Re: 250 clifford valve cover question

When I purchased my truck, the PCV wasn't connected to the 250's manifold. Not knowing it should be hooked together, the engine was leaking oil all over the place due to built up pressure. Just want to give you a heads up in case you start experiencing the same by going without the PCV.

Hey Sal!!
I used the pcv oil fill cap when that valve cover was on my 250. I used a clear hose run to the intake. Never saw any oil residue in the hose so I knew the pcv wasn't sucking any oil into the intake. There should be some fine grade steel wool in the breather box too.
Air in the back, fumes and air out the pcv.

Funny thing is when I got it I put it away and then forgot about it, untill I "found" it last week. Thanks for the tip I will do the same, and try to get some pics up soon.
