The original 272 had the vent with the filter but I have seen later Y blocks that do not have that so how does the ventalation systems work on the later motors and what different parts do they have compared to the earlier motors,I will most likely adapt a PCV system when I put a 292 back in.  Now can I still put on the earlier vent on a later motor for the look of originality only.

There are several previous posts on this topic.What you need to get hold of is a valley cover from a T-Bird y-Block.They had the roadraft tube hole at the rear of the cover and the tube ran down the back of the  motor.That hole will accept a rubber grommet to hold a PCV valve.From there you plumb a hose into A)  the carb if it has a fitting or B)the intake manifold as close to the centre as possible.Do not plug into the rear where there is a vacuum outlet because you may cause a lean fuel mixture in the rear cylinders.Use a I believe 1 1/4 inch cup type plug to fill the hole in the block where the roadraft tube bolts on.Bolt the tube back on if you want the appearance.Make sure your oil breather cap is clean so air can enter or create a closed system by using a cap with a fitting to run a hose to the aircleaner.Search previous posts for more info.I did my 56 awhile ago and it works very well.No more puffs of smoke from under the motor at idle and my garage no longer smells of fumes after parking the car overnite.Hope this helps a little.

  

You dont need a T-bird valley cover, since anything labelled T-bird seems to be a lot of extra money.  58 up cars and trucks have the same hole located in the rear of the valley, but it can be difficult to find the right grommet for the application.  Y trucks started using PCVs in '62 or '63.  They have a neat little cap that bolts over the hole of discussion, and a hose attaches to the cap, to run either to the stock location on the 2V intake, or to a PCV port of a later carb.  The actual PCV would be inline.

I'm running a 465 Holley on my 272, which base plate doesn't have a pcv port, so I'm running the pcv hose to the air cleaner, any pros or cons on this? Seems to be working fine so for. Gary

A local junkyard has a few of the 61-4 trucks and will check them for the pcv system and valley pan

If you find one or more you might want to take them all if the price is right.always someone looking for one on this site.

  

63 64 pickups are the only 2 years that Y-Blocks were factory equipped with PCV.

The road draft tube can be bolted back to the side of the engine for ‘looks’ by using an expansion plug in the block hole and cutting off the ‘U’ tube on the block side of the road draft tube that normally sticks back into the engine at that point.  This will give you the originality look while stopping the potential for any oil leaks that can occur at that spot.

Your description sounds like you have no vacuum to the PCV valve which in turn means it’s inoperative.  A spacer under the carb with a direct vacuum port is the ideal option in hooking up the PCV valve in your case.

I fixed the pcv valve always open, so it's a direct line.....will it still be inoperative? Gary

The TBIrd parts suppliers have a kit which consists of a base plate with a nipple, valve and hose for both the A and B manifolds. It is designed top be used with the TBird valley cover, but can be used with the later car cover if the cover is like the TBird one.. Not sure about the truck cover. The later Fords had a spacer with a nipple, and you should be able to get that at a junk yard.
