Draft Tube

[George Hamilton]

I have a 1962 Ford 292 YBlock engine in my 1955 Ford Fairlane Town Sedan.
I have read you have to clean out the draft tube on occasion. From what I have read the YBlocks have canister attached to the tube with a return line and a filter. My YBlock does not have that. The tube comes from in back of the engine by distributor and runs down passenger side of engine. There is no canister. All I see is a little wider part that is connected to block and tube runs into that. Does anyone know if this type of set-up needs cleaned inside or not and if so what is inside that part of the connection.

Post some pics of what you are talking about. Then we can give you correct information. What you described seems to be the later PCV system (after the draft tubes). Cleaning out anything that you are not sure of is always a good practice.

Pictures would help. But what I’m reading says you’ve got the rear draft tube like was used on the Tbirds. They don’t have the filter and drain back like the car with the front side mount canister. There is a baffle in the valley pan, and the mesh in the oil fill cap needs to be cleaned.

Wild guess is that the trucks used the same system as the birds. I don’t know, never had a truck.

My 55 still has the original 272 Y-block. Here are pics of the original style draft filter. It's located on the left (driver) side of the block toward the front. I didn't take a pic of it before I removed the cover. I'd like to know the best way to clean the filter element.
Pic one: filter element in my hand
Pic two: filter element with cover removed
Pic three: filter housing with element removed
Pic four: filter housing cover

Yeah, I think you are right. I read about that. This engine has the built in engine mounts on the bottom that are cast into block like for the trucks. Although it is sitting on mounts in the normal place up front. I have just ordered an original style oil filler cap from Concours Parts to see if that helps. What I have on it now is an Edelbrock cap and it is filled with foam filter. All I was concerned about was a bit of oil drip from the tube. Not too bad yet. Thanks for the info.

The only way to get rid of the drip is to replace everything with a PCV system. Since it will move some oil vapor, there’s invariably the odd drip even from a new tight engine.

Yes, the foam will be too restrictive and not allow sufficient air flow.

It looks like the one in this illustration. There is nothing to clean out unless you'd like to give it a fresh coat of paint, or its been damaged. Original equipment on '55/'57 T-birds.

I was messing around with the suspension under my 1959 Merc with a 312 and I notices the canister and took a couple of pics here for reference. It may be a little different than the 1962 set up, but could be a good reference for others learning about Y blocks (as I am).

This shot is from under the car. Front left side of the motor. The fuel pump is good for reference.
