pcv conversion/ valley pan ?
I was looking at doing the pcv conversion on my 58 292 and was looking for the location to connect the pcv that is supposed to be in the rear of the the valley pan but the only port I have in the valle pan is at the front almost directly below the front of the intake. Is it possible that the valley is on backwards or that I can use this port and connect it to the spacer under the carb?

Just looked it up in the Illustrations CD; that is a bizarre location??!! Well, I'd still say that is the proper location, but I'd use steel tube to get close to it, with a rubber piece to transition. As you can see, there is an elaborate setup to wring the oil out of the vapor. I'd see if you can modify it so the PCV valve itself sits vertically, or at least horizontally, not upside down. Maybe come off the upper can-section, and cut off the draft tube completely?
Hoepfully someone else has done this to a Y-block before??

I removed the pipe and plugged the side hole. Then I drilled a hole in the "can" and used a rubber grommet and a generic PCV valve from auto zone. Works great and I have had no problems. It also prevents the y-block from "marking it's territory" out the vent tube.
Hope this helps.

Not to sound naste but I did alread do the search and read all of the ones that are in there but with the year and engine combo I have there was a lack of info, even in this current discussion the difference between the 60 and 58 has come up since mine does not have the can and tubing coming off the back of the valley pan. Anybody have anything to add that has done this on the year or engine?

There are some different , I can tell you what I have ...... one 56,two 59s one 64 .......... They all have the oil fill in the right front of the valley cover with a filtered cap.........The 56 came in the car new so I know it is correct. It has a filter and road tube on the lower front left side of the engine. Nothing off of the back and no holes caped over.One of the 59s that came from a truck has a one inch tube off of the back on the left side. The area where the front lower filter and tube would go is cast over ,never opened up from the factory.
The other 59 that came from a ranchero , is the same as the truck engine ,one inch tube down the back ,only it has a plate bolted in the lower left front where the filter and road draft is on the 56.
The 64 has a provision in the left rear of the cover to put a 3/8 hose on. I believe that is where the PCV went in . But where it went from there I don't know as some of the parts are missing. The area where the filter and road draft went on the lower left front is the same as the truck engine ,never was opened up at the factory. .... I hope this helps . JIM

Thanks Jim, I took another look at mine and I have the oil filler on the front right and a bolt in the rear center of the valley cover. I must have mistaken the hole in the top of the intake just infront of the carb when I originally posted. Know I have to figure out if the bolt does anything or if I can unscrew it and put a pcv in and run it to the hole in the top of the intake?

my first 56 292 y-block, had a vent tube with the breather cap. i modified the breather cap so i could use a PVC valve in it by extending the upper side of the can. by welding on a piece of steel tubing and a flat washer. so it looked like the can had a filler tube on the top edge next to the hold down nut. i drilled the washer to allow for a grommet. then pushed a PVC valve into the grommet. i then cut the vent pipe off and blocked the hole with a piece of sheet metal welded to it.
i picked the PVC valve from a parts catalog from a newer similar sized motor. then ran the hose to a newer carb, i had installed.
the system worked very well.
so i did the same mod to a 272 y-block in a different rig.

cbass 139 ,I don't know if you use the H.A.M.B. , site or not , but there is some information there . I had trouble getting the search to find it until I entered " 292 pcv " , then it came up. Somebody put up pictures on there change over. They blocked of the lower left front filter and draft tube. Then they drilled a hole in the right valve cover to install a groment and the pcv in from there they went to the intake manifold just in front of the carb. I don't know how they did the valve cover inside area under the pcv. They left the oil fill cap untouched, but that could have a hose on it to the air cleaner. Thats the way the 65 ford falcon , mustang 6cy was done. Jim
