Do I need to install a PCV valve (1962 223)?

1962 F-100 Custom, original 223 w/ original 3 speed behind her.

I need help. I'm new to these motors and I can't seem to find what I'm looking for on it. I have an oil bath air breather. Never fooled with one before. There is a line that runs form my oil fill cap to the air breather. I assume this is for venting. Can I get rid of this and the oil bath if I install a PCV? What are some of the methods y'all have used to retro fit a PCV valve? Any advise is welcome. Pictures speak a 1000 words to me. I have included two pictures of my motor.

Please excuse me if this seems to be an elementary question. My background is with 66/67/69 Stangs running 289's and 302's as well as LS1's. I just bought this truck and I my learning curve is steep with this motor. There just isn't a lot of information out there on a 223.

I can't really see from the pictures but there should be a draft tube running from the side of the block down below the oil pan in the vicinity of the exhaust pipe. This is what they used before the PCV system which came along around 1963. If the draft tube is there, all you need is a vented oil filler cap. Actually, if the tube to the air cleaner disconnects, the oil cap you have is probably fine. I would pull the draft tube off the block to check the wire mesh filter in there. If cruddy, it can be cleaned and re-used.

Hi, as mentioned, your engine uses the old road draft system to rid the engine of crankcase vapors. The tube is on the rear drivers side of the block. The forward motion create a suction at the tube exit so air is drawn in the valve cover and out the tube. You probably notice an oil drip on the floor, right under the tube. A PCV system much more efficiently remove the contaminants from the crankcase, and reduces or eliminates sludge build up. The issue with a PVC system on a 6 VS an 8, is on an 8 the PCV system draws air into one valve cover, down through the oil pan, and out the other valve cover, and into the intake manifold. On our 6 cylinders, air is drawn in from the front breather, and out the PVC valve on the back of the valve cover. Better then nothing, but not scouring the whole engine like the V8. You can change air filters (I like the vintage look you have now) and just find a push on breather for the oil filler. Old push on caps have a steel wool type filler to somewhat filter the air going into the engine, and your road draft system will work as designed. If you modify the valve cover for a PCV system by drilling a hole and installing a grommet, you will need to baffle it from underneath or you will suck up oil off the top of the valve cover. Good luck
 
Pvc systems in the f100 first came out in California, they replaced the road draft tube with a canister tube system that came up instead of down, bent towards the front and bolted to the ear on the intake that holds the throttle linkage, then came the valve, short piece of rubber, then a 90* that screwed into the intake under the carb, breather cap is a must jc witnney has them on epay for about eight bucks.
Searched my stash for pics but photobucket fiasco ate them
 
That's a really clean looking truck! (y)

For sure you don't really have to have a PCV valve. But X3 if it were me I would install a PCV system "a closed type (the very best there is)" I also like those old oil bath air cleaners too. Good luck on your pickup :nod:
 
I know this is a really old thread but here’s some pics of what unibody madness was describing, my ‘61 ford f100 with 223, the original pcv I believe these were on California trucks. It’s a canister that bolts where the road draft tube would go and has a hard line that attaches to the intake manifold with a short rubber hose. Pcv valve is at the rubber hose end. Here’s my original one pics attached!

Paps61 There are so few pictures of what the original parts looked like as by breather system was a bit messed up from the previous owner. He modified the can shown in your picture to be more of a chimney with a filter on top. I had so much blow by that it would smoke like crazy and not do it's actual job. I am updating it to be like the one you have shown. The one "port" in the intake manifold is used for upgraded brakes and the second I am using for the PCV fitting. I also need to get the oil bath housing that I have modified to accept a standard paper filter. I know there is a post on here with pictures.

ArrowAndrew, the restriction the PO put on the crankcase breather is way unacceptable! Venting blowby to the atmosphere is fine with the large tube, but there should never be backpressure on the system! (What a corny rig- why would the PO want the fumes up inside the hood area? (n))

To add to this......when the brakes were upgraded the old hole where the old brake stystem was is mounted now only has a 5/8" rod going through it so you get some nice breeze in the cab when the windows were cracked open (the cab is sealed up tight)..mmmmm. crank case fumes......

I actually modified my oil bath air cleaner to fit a paper filter but also to a Weber carb, the pics above were original before I started restoring the truck so it’s much different now, I kept my brakes manual and found a direct replacement dual master cylinder from Leed brakes keeping it 4 wheel drum. Working on modifying this pcv line since I now have a Clifford intake on it. I’ll try to make a post of my oil bath air cleaner mod.
Here’s some before/after pics

Wow...Beautiful engine!

Thank you! I just saw the pic of yours I didn’t realize you sent an attachment it looks like they cut the original line and just put a breather on it, you could fab up a line to still make it look original. If I don’t end up using the line on mine I’ll let you know, your welcome to it if I don’t use it.

I have not read the post on proper ways to share a picture yet.....sorry guys
I thought of some ways to fab up a small line to use. If you do not use it I would be happy to give a good long term home!.
Can't wait to get my engine back from the shop and truck out of storage. Wisconsin winters can be long.
 
I've asked about making a retrofit PCV valve system look like a factory fit on this forum earlier. California mandated factory PCV Valves on new 1961 and later vehicles, then in late 1966, they mandated all post WW2 to 1960 vehicles registered in California and non Califonia 1961 & later vehicles not fitted with factory PCV Valves be retrofitted with "State Approved" universal PCV Valves at a "State Approved" garage. It was illegal to install a factory fitting OEM unit to a 1962 or earlier California registered vehicle if the vehicle did not come from the factory with a PCV valve at the time. My dad's 59 F100 is an example of a vehicle that could not be fitted with the 1961 Ford PCV Valve legally by state law in 1966 for the 1967 DMV renewal. The Sears garage that retrofitted the engine had plugged the draft vent with a rubber plug, punched a hole into the valve cover, put a fitting onto the cover and ran a 1/2 inch heater hose to a PCV Fitting installed on the spare intake vacuum port. 1963 and 64 223 blocks have the old draft port on the block plugged and run a line from the valve cover to a PCV Valve bolted in with a 90° brass fitting on the vacuum port. When the Sears garage retrofitted the 223 six on my dad's 59 F100, they replaced the original oil cap with a Stant SO 68 oil filler cap, for proper breathing and pressure. If you are retrofitting your pre 1963 223 six with a PCV Valve, there is a PCV valve for the Ford Y block V8 engines that will work. NAPA sells it under their name. I also have a 1962 Rambler Classic with the 196 OHV six cylinder engine. It has the factory PCV valve per California regulations. It turns out that the PCV Valve used is shared with Ford and other makes. That same PCV Valve is also used on Ford Falcons and other Ford cars with 6 cylinder engines. I have attached some photos from a screencap from NAPA Auto Parts.PCV Valve Ford F100 223 6 Rambler 196 6 Engines.jpgStandard PCV Valve - Rambler & Ford.jpg

Nice pictures of the Weber Holley adapter ( post #11 lower left) to large Holley air cleaner. Where can one of these be purchased. I have a 62 Falcon Ranchero with 200 cu in engine adapted with weber carb and would like to use the larger style Holley air cleaner. Please advise.

Yes, this is originally a California model truck. Most parts of California required this fitting to be sold new at a dealer. Sadly, when retrofits were mandated by the state, it was illegal to use this factory part on vehicles not originally equipped at the factory with these OEM parts in 1966 for the 1967 registration renewals. This part is made out of brass, in case anyone is thinking about replicating the part to retrofit a PCV valve. One can modify the old draft tube and do some soldering with brass plumbing fittings to run a hose from the tube to a PCV Valve calibrated for the 223 six engine. I posted the NAPA part; I believe the Standard Motor Parts stock number is V100 for those who don't have a NAPA parts store nearby but have a mom & pop type parts store with parts for older vehicles.

Hey flatford6 are you referring to the Weber to
5 1/8 adapter? The air cleaner I’m using is actually the original oil bath air cleaner, i converted to a paper filter by cutting out the top section and then cutting a 5 1/8 larger hole on the base. The adapter I used is from LCE performance but I believe redline also makes one it’s just the LCE one is better quality then I just replaced the center bolt with a longer one. If you are looking to use your original air cleaner this could work, but if you’re just looking to use a round air cleaner I believe they have some with a Weber base. Here’s a link to LCE performance (great customer service)! The other adapter I used is just a 5 1/8 roundx 1 1/4” tall spacer with o-ring to raise the cleaner to clear the fuel line on the carb.
