PCV valve

Here is an idea I came up with for my 292 cu in y-block. I was told if I didn't want to pull the intake to mock up the valley cover to accept the rubber grommet and the valve was to run a inline PCV valve. So this is what I've come up with. The valve in the picture is for a 1966 289cu.in. Ford Fairlane. I got the other part from NPD, this fits where the draft tube would be. All I need to do is use some gasket compound and seal it there. I'll run a 3/8's hose to the front of my edlebrock 500cfm carburetor. I'd like some input if this might work?....Dave

From the photo you show there is an arrow pointing in the direction of the housing you purchased. Is this arrow for the FLOW OF AIR that goes into the carburetor/intake to be reburned? if so, this pcv valve is backwards and you will not get any flow whatsoever. You may want to remove, blow through the valve and see which way the air will travel..

I am interested in your small housing there. Do you have a part number for that? And... how well does it fit the original PCV valley pan that Ford made?

If you're going to cut a hole and make your own the measurement is of no consequence of course. Can you give the diameter of the housing?

I do have a PCV system that I used on my 292 that also runs an Edelbrock 500 cfm. It carries the same idea as yours but I used a pcv valve for a 302 Ford that had a hose nipple at both ends and simply put that PCV valve inline with the carb and a housing unit (Ford) similar to what you show. If you would like to see photos of the parts and an article on procedure, shoot me an email.

The part you see there is from National Parts Depot, I'm sure you've heard of them. The part number is T-6758 it costs $24.95 with tax. It just sits where the old draft tube does ans screws right into the valley cover. The cover is about 1 1/2 inches across and 1 5/8 tall, made out of aluminum.
 
If you install it and have a sudden oil consumption problem, there is no baffle under the cover. Some covers had a baffle, some didnt. If you need instructions on how to make a baffle, ask.
 
I agree with the Rev... I think you have the flow backwards. You may be able to screw the PCV valve into the intake and run a hose from it the the adaptor.

edit; Sorry reread your post, can't screw it into the front of your Edelbrock, already has a nip.
 
Heck, I just took an old sock and tied it to the bottom of my draft tube. You don't get near as much oil fumes with the sock as you do without it.
 
Great idea, but yes it is backwards. I had thought of that idea as well before I was told it went the other way.
 
My valley cover does have a baffle, I went from the side mounted draft tube to the one that discharged out the back of the block.
 
well I installed a PCV inline one with a 283 that goes up to a 305. I started the car after changing it over and it ran like it did before I put the PCV in line. I took it for a short spin, didn't want to go to far, as I thought I might have to walk home if anything should happen but nothing did. It runs just like it did with the old draft tube installed. I even let it hang out hard in first gear and on miss just like it ran all summer long....

Installing a proper sized PCV valve shouldn't affect how it runs... :eek: It just removes the unburned gases, corrosive materials and moisture from the crankcase and burns it instead of dumping it into the atmosphere.

I hope it was running good before??:confused::confused:
 
A properly calibrated PCV is very important. Dave got away with it because the valve is sized for a similar displacement engine. That is a good rule to follow. The generic valves sold off the " Help" rack at the parts store are nothing but spring loaded vacuum leak. Ford had/has over 50 different calibrations for PCV flow ( EVxx ). Some are high or low flow at various vacuum levels, some are actually stepped flow over a range of vacuum. Having the clean air enter at the farthest point on the engine from the PCV is optimal for effective total crankcase scavenging.
 
djpink1947...Can you get on to HAMB? I have asked a lot of questions and received many replies. If you have any questions, just ask away!
 
The 63/64 trucks have a pcv and found one in a local junkyard that donated all the parts for the 292 that will some day go in my 55.
 
I have used the '63-64 Ford 292 truck type PCV system on several Y-block Fords for over thirty years.. They are simple to install and work good...
On my T-Birds, two, 56-57 with the aluminum valve covers, there is no need to put a port in to the aluminum cover..
On some Y-blocks I have used a Chevy type of PCV and rubber grommet placed into a valve cover. I always fabricate a baffle into the bottom of the valve cover, to eliminate oil being drawn into the PCV system..
 
Fellas....
Re: The 3/8 hose. Be sure to use pcv/vacuum hose not common fuel/oil line, A good engine will pull 15 inches of vac at idle and close to 28-30 inches on closed throttle deceleration, the non-vac hose is subject to collapse where the stouter vacuum hose will not. Don't ask how I found this out.....RooDog
