Can someone provide some info or post a photo of their Offy cover w/PCV
installed?
There is one smal boss on the inside of the cover and that is somewhat on the side. IM not sure that's where they go so I could use some help.

The Offy valve cover has no provisions for PCV. None. It was designed in early '61 when PCV did not exist, and has not been changed since that time. I've been on the phone a few times to Tay Offenhauser trying to gently push him in the direction of reworking the cover for easy compatibility with all slant-6s made between '60 and '80, not just the first two years' worth of production. Thanks for the reminder to call him again (though he didn't seem all that interested in making any changes).

There are no internal baffles, which is a problem, 'cause it means even if you drill your 1" hole and put in a grommet with a PCV valve, you're going to be sucking splashed oil into the intake tract via the PCV valve.

Unless/until Offenhauser updates the part, the best way to install PCV is to obtain a Stant 10078, Wix 42997, or AC-Delco 12C26 breather cap:



Drill the Offy cover at the rear to accept the grommet for this cap—that'll be another item to buy; it's a Dorman #42344 (breather grommet for 1970-1995 Chrysler products)—and push the cap into the cover. This cap has an internal filter and a 1" top hole, so just snap a standard Chrysler PCV valve grommet (such as Dorman # 42064) into the top hole and pop a standard Chrysler PCV valve into the grommet, and you're all set.

The folks from OZ are going to give the Offy it's death if they don't retool.

Last time I checked they still don't have a website.

Slants are getting more popular as evidenced on other boards and this one here.

I love their parts and own 3 Offy intakes.

Hmmm....my Offy cover has got a pretty stock looking PCV on it.
I bought it 2nd hand so have no idea if that's how it started out as or not.

That'll be "not"...somebody added it. Pretty nicely, it looks like.

Does the angle of this PCV valve make it sufficient to use w/ no baffle or do I still need to find a way to incorporate one some how?

The breather (w/angled PCV grommet hole) contains an oil separator that sort of almost mostly substitutes for the original-equipment baffle.

Thank you for that information, I appreciate it.

I ordered the Balkamp 7031372 crankcase breather cap from NAPA. They didn't have the Stant listed. I told them I needed one for an 83 Buick regal w/ the 350/5.7 diesel. They gave me the Balkamp # and the picture was the same. The grommets fit it also. It has a wire mesh screen up top and an polyester looking filter material at the bottom. Is the Stant the same? I had expected a metal plate of some type.

Any how some pictures of the Stant cap, online, have the same screen in the photos. I imagine the filter material will be oil soaked in time, so I'll keep an eye on it. If it does so fast, I'll probably just pull it out, clean the screen and put it back on w/out the filter material. I just thought I would post this for the cross reference. Cross references can never hurt.

On a side note, It was cheaper for me to go through NAPA and get it next day, versus paying Rock Auto's $10 shipping on top of the $7 something purchase price for all three pieces. Thought I'd throw that out there for anyone shopping around in the future. Heres some pictures...and Dan----> Thanks

Yup, that's the right breather cap!

I've gotten the car back from Texas. Now I can actively (and accurately) participate in the board... =)

One of the first things I really want to get done is this PCV Install... I'm going to begin gathering the parts and hopefully the project can be done in one afternoon with my buddy pretty soon.

ONLY: I am pretty sure this breather cap will not fit my situation because of the heating box. SlantSixDan, you are 100% sure it will fit? Because... how? Haha. The flat portion/rear of the valve cover is directly below the heater box; there's maybe enough clearance to slip part of my hand in there, little else. Was I supposed to modify the heater box? This is all if I have completely misjudged the size of this item; I picture it having a similar size as a normal oil cap... if I'm wrong, then sweet! Going to Pep Boys later on to check for this.

Beyond that little hiccup, where do I run the PCV to? I have an Edelbrock Performer 650 on the car.

The Offy valve cover I bought during the group buy now has a stovepipe for the PVC as well as front and rear baffles. I did not want the later model looking parts so decided to try this route. You can take a look over at FABO - http://www.forabodiesonly.com/mopar/sho ... post916876 including pictures since I haven't a clue how to include pictures with my post (guess I need to read up and figure it out!

That's nice work you did! Please do post the pics and descriptions here using these instructions.

That's a good point; it might not fit on the '60-'62 A-bodies for that reason. I keep meaning to install my Offy cover on my '62, but life keeps getting in the way. You could drill for the breather grommet on the outboard wall of the valve cover rather than the top. If I were to do this, I'd probably put it between #4 and #5 spark plugs, to avoid getting in the way of the transmission dipstick, though be careful not to worsen the already tight clearance on a '62 for removing the oil filter. Or, option "B", you could drill a smaller hole on the inboard wall of the valve cover facing the driver's side of the engine bay, install a hose nipple with some very coarse metal mesh (e.g. from a copper scouring pad) loosely packed into it to provide some oil separation, then use a Chrysler p/n 4315 704 formed hose elbow. One end goes on the valve cover nipple; the other end accepts a standard Chrysler PCV valve.
If your carb has no PCV nipple on its base, then you'll want to drill and tap the manifold centrally. I recommend the outboard wall of the intake (facing the driver's side).
