Are the valley pans made for a road draft tube or PVC the same.

The answer is ‘YES’ if referring to the road draft tubes that originate at the valley pan.

I am going to put the factory PCV system on a valley pan that had a road draft tube.

Just did that myself. I used a Casco kit. It uses a plate under the carb and a hose that runs down to the PVC. A rubber grommet goes into the valley pan. The PVC plugs into the grommet. You have to tap down the threaded tube where the old draft tube screws in so the PVC will seat. I used a socket to tap it down. My engine seems to idle better with the PVC and no more smelly garage!!

I recently picked up 64 292 to get another PCV system and distributor along with a truck timing chain cover so I can use a Hurst style mounts to put a Y in a 40 Ford if I could ever find one I can afford.

I have a valley pan with the hold down tube removed. Also removed is the splash piece underneath. Wanting to sell. Offers accepted. Very good shape, may need some minor straightening

Paul 2748: If you can, put that splash guard back on, for use with a PCV setup.. Either that or some other form of oil interceptor will be needed. PCV setups can have oiling draw problems if not installed suitably..

When I purchased by 55 Tbird, it was bone stock. The engine was tired, so I built a new motor. I left the down draft tube believing if it worked in 1955, it must be good enough. Except for the cylinder block, my new engine is mostly a 1957 292 and it runs great. It has a neoprene rear seal. Even with an all new engine, it always leaked a little oil. It also smelled up my garage, which did not make my wife happy. She always thought she smelled gas.
I decided to install a PCV system about three weeks ago. There was an immediate improvement. For some reason, my engine idles better with the PCV. It's much smoother. Interestingly enough, the oil leaks have stopped too. Rarely does something I buy for my car work that well. I'm a believer.

Not to refute, but as a retired Aircraft Maintenance Instructor, Automotive Instructor, it always surprises me in this day and age that folks do not remember these simple abbreviations. PVC: polyvinyl chlorine is a piping that is used in piping for water, irrigation, plumbing, etc. PCV: Positive crankcase ventilation is a system to remove fumes/blow-by from an internal combustion engine. We use disc brakes on our cars, not disk breaks; and we go from here to there, not from here to their. I guess this covid quarantine has me on edge. LOL Joe-JDC

As I grow older I find it harder and harder to proof read what I write. By the time I'm 80, I should be barely understandable. Anyone old enough to love Y-Blocks knows what I'm talking about.

Phil everything you are saying about a PCV system was exactly the same for me. Even tho I had to do that step revision on the teapot looking fitting and used a valve that screwed into the intake/or carb base the smell is gone from my garage. I was able to buy a Thunderbird side block plate for the old car side draft tube/filter too. Took me 9 years to do it.

The splash guard that is missing is the one that points downward, not the one underneath the hole for the draft tube.

AFTER DEVIDING THE INTAKE(4V 600HOLLEY),FOUND THE blo by fitting created rout idel. so i blocked the fitting at carb and took the hose to the air cleaner
inside the air cleaner filters the292 has very little blow by and the carb and air cleaner are raised 3 in.s no oil travels up to air intake, and idle is great. i recently put on a home made alum. plate that has a baffel it the breather ,as well a larger hose to air cleaner. this engine has full pressure to rockers, lots of oil drains threw pushrod holes as well as drains holes in. heads on exhaust side. i found pcv system more trouble than worth
