I've seen this setup on big trucks like grain haulers and dump trucks but only once on a pickup. It was an old Air Force truck that still had USAF #XXXX stenciled on the firewall and had the PCV system and a full flow oil filter. Clean and save it---it's rare.
No Pic ? O.K. , I'm not seeing any new pic but , the big sheet metal tube that fits into the cylinder block , is what you want to BBQ , don't forget the Marinade ! Remove the brass elbow on it before you begine grilling . The steel cylinder that is screwed into the brass elbow , is the PCV valve proper , you may notice it can be taken apart , I say resist the urge to do so , just soak it in a metal cup of brake cleaner or mayhap carby cleaner , beware that's really nasty chemicals so wear gloves and _don't_ get it on your skin ! . DO NOT cook the PCV valve ! . I hope this helps , I havn't touched a 'puter in days , still having neck/spine pains and now a terrible cold . went to Death Valley for some R & R and SWMBO's classic Mercedes blew in youdon'twantobeafoothere , Nevada...... It's home now and I'm poorer than a churchmouse due tothe $700.00 + tow job I did plus I still gotta FIX it.... When it rains , it pours , no ? Take your time on that PCV setup and it'll be great , it is a period correct dealer or factory acessory , should have " AC " stamped faintly on the valve proper once you get it cleaned off.... Carry on Gentlemen....
PCV Pic O.K. Jon ; I finally got a look at the pic ~ A & C are the same part and D is the clamp that holds it from wobbling loose. loosen & remove the clamp and then unscrew the brass elbow and PCV valve , cook the big sheet metal cylinder , it'll really make a stink so DON'T do it if SWMBO is home ! . DO NOT bead blast it either ! that will cause engine failure .
one more time... ok, still haven't gotten SWMBO to leave the house yet, but i did get things disassembled and cleaned off a bit. here's some pics. please shout at me if there's something more to disassemble before i go cooking it!! jon if you look closely, you can read "AC spark plug" on what i believe is the PCV valve setup. the tube is welded to the top piece, not sure if that's OEM, but the weld looks kinda shotty. thanks!! jon
BBQ Your Breather To-DAY ! O.K. Jon ; The big tube thingie is wht you want to BBQ ~ wire brush it of all the paint you can first tho' The PCV valve in the lower pic ~DO NOT heat it ! next to the tiny printing should be the AC part #....... Soak it in some cleaner , whatever typ floats your boat , for a few days whilst you're screwing 'round with the breather tube . If your vacuum cleaner (connected reverse so it blows , dig) shows no resistance , you can prolly just wire brush , rinse off and re-paint the breather tube , no BBQ'ing required but usually they're full of sludge and 1/2 dried oil gunk . Keep up the good work ! if you decide to drop this project , mail it to ME and I'll install it on MY '49 ASAP
thanks nate!! i'll be on the lookout for another setup like mine, just for you! i found a glimmer of blue paint on the valve cover, too which lends to your theory about a 235 from a passenger car. jon
got it all cleaned up, going on the grill today! i wonder if the it needs to be under the lid, or if open air is good enough? jon
Keep a lid on it! That way every time you pop the hood, you'll catch a faint whiff of oak, grapevine, hickory, pecan, or what ever kinda wood you'd decide to throw on there! Or if all else fails, just ask Andy. He's been there- done that!
Whichever allows you to get it hotter . Remember : we're NOT kidding about the amount of smoke & stink it'll make , DO NOT BBQ it with SWMBO in the same county ! -Nate
PCV valves OK, so I read this thread a couple of days ago, figure I gotta find one of these pcv valve set ups. Went to the swap meet today at the Houston Drag strip, didn't find one, but did find a complete 235 with a cast date of H-9-7. A car motor the seller claimed was in a 53 AD. I doubt it, wrong front motor mount. i was tickled to get it anyway. Now I have a running 235 and a spare. Deals like this really make SWMBO and the kids proud of me. Got it cheap, had to have it. Still no pcv set-up.
Next time you do that, call me! I sent all afternoon fixing my mother-in-law's sink! If you had called and said "meet me" at the strip, I would have had an excuse not to do that!
I didnt decide to go until I was practically there. A bunch of folks there, with lots of stuff. This is the meet which replaced the old Del Mar Stadium meet. First time at the strip. There are 2 planned for the houston horsetrack up closer to you. All 1/2 day meets that start at 6A and end at 12 noon. Sorry you missed it, www.swapmeettexas.com I missed replacing the speed control on my mother in laws ceiling fan. Figure I'll do it later. You looking for a buildable 235? Jim S.
CHEAP P.C.V. Systems O.K. , here's what yiou gotta do : Find the biggest , nastiest , greasiest old farm truck or remains sitting in a field or in the way out back of a junkyard and raise the hood and there it'll be ~ esp. on ex-firetruck chassis or old munincipal trucks as this was (at one time) a popular accessory on fleet vehicles.... The fact that it's covered in 1/2" of the nastiest greasy dirt you ever saw olny means it's like new underneath all that grime....
Sam Houston Swap meet! Been to the last 3 of them! 7 miles from the house. As far as a buildable 235, my mother found "a Motor" in dad's shop last month and it is probably a 235 or possibly a 261. I think it came out of a '62 panel that dad bragged about! Stay tuned!
Ok, when did PCV valves show up? I suspect the late 50's, early 60's is likely the era of vehicles to look at? Wouldn't it be almost as easy to modify an old breather tube and make your own pcv set-up? Thanks for the advice Nate. Ken, let's hope your mom's engine is the 261 Nate makes us all lose sleep dreaming about. Jim S.
