Making a PCV port in a non-ported early style valley pan or an aftermarket flat aluminum valley pan is not so easy. You can't just drill a hole in the back of the pan and stick in a PCV valve. It has to be baffled. If it were me, I would find a later style valley pan with the breather tube and PCV port and make or buy a block-off plate for the road draft tube. Done and done. Just my two cents worth.

" You will have to use a PCV system with this setup" is the important part of this quote. You need a vacuum source to the carb/intake with a PCV valve in the hose. Then you'll need an air intake to the motor, either vents in the valve covers, or a push on breather in the valve covers. No forced airflow thru the motor, you'll fill up with water/sludge, or pressure. Pressure will force oil out everywhere.

I know it's not popular here, but 69 camaros used an oil fill tube with a sealed cap and a bung to thread the PCV valve into. Or a hose fitting and an inline valve. I've used them as a fill tube, with a hose fitting to the air cleaner on two of my motors. Works slick

thanks for the reply, I think I'm going to give it a try and see how it goes

Yes. I did that on My '48 Ford because the stock draft tube interfered with the axle. Simply made a mounting plate out of .250" flat stock and welded the appropriate sized J bend tube to it. Used a breather cap on the end (K&N type). You will have to use a PCV system with this setup.

has anyone heard of making a oil filler tube and mount it where the hole for the draft tube was, I have offenhauser valve covers and no neck on my valley pan cover, just wondering or I'm going to have to replace the valley cover to get oil in the engine, ive been looking at valley covers from vendors you guys gave me and this idea just came to me
