Subject: Re: {Chrysler 300} Oil Breather Unit Our second 300G, purchased 1975 had the PCV in the right valve cover and line connected to the ram equalizer tube. Worked so well I added the same system to other draft tube stinkers. Has anyone seen a Douglas Donaldson valve? Used in the 1950s? Same basic idea, large rebuildable check valve.
My G did not have a PVC as far as I recall. As I am new to the 300 club and to my G, and not too up to speed like I am on my '56 Windsor, I will take a stab at this breather issue. (Don't shoot me if I am in left field on this.) Noah, a fellow 300G convertible owner whose car was manufactured for the CA market, showed me his PCV setup which draws vacuum from the crossram. Not wanting any oil drip spots in my garage, I removed the draft tube and replaced it with a cap (see below) a PCV value and hooked up a hose to the crossram. Now I don't have any oil drips when I come home from a trips.

Napa part 7032851 is a version of what I need, except it is a low profile unit. Any thoughts on this? Ron K that guy had no idea how PCV worked! That setup does nothing at all except wreck the air cleaner and the valve cover . — to get flow you need vacuum ( via pcv valve ) and a place for the new air to go in .. No other openings allowed . Here he had three! The old fill tube with oiled mesh is actually good , same thing it did with the draft tube , so wide in diameter and vertical rarely could blow by push oil up there . That piece of wisdom was lost with Chrysler’s sideways 7/16 PCV hose . But draft tube had to go and you need vacuum . I once bought a 67 273 barracuda , this genius had put on two beautiful mopar performance valve covers , I did not notice both had oil fill caps. Drove from California to Boston , he told me “a ready to go restoration” All that went wrong or fell off in 2500 miles would fill a book , but first day driving in mountains to Oregon , after an almost catastrophic brake failure in the first hour ( a groove defect in master cylinder lid machined surface was filled in with silicone caulk (!) — nice in mountain braking , —the fluid all leaked out with heavy use of brakes —causing the “squirt “ inside )— so I started smelling hot oil . Thought “oh no rear main leak -on exhaust ?” Opened hood —entire “ spotless “ engine , firewall everything under hood was covered in two quarts of oil spray Blow back had blown out the dipstick right out of its tube and the oil followed ! Why i know about the grommet etc on that trip , wired down the dipstick among the Sequoia , kept a light foot . Later the steering box fell off frame , only one bolt was left loosely holding it , ( thank you Jamie) both large door striker bolts unscrewed doors flew open on highway bump , and best of all he had machined nose of starter to go in further to try to fix a blown ring gear , causing in op jammed starter every 4-5 th time . Left it idling overnight more than once . How some individuals survive mixing adulthood and cars is amazing .. jkg Sent from my iPhone not by choice Check out this "antipollution" setup I took off my second '56 NYer convert that was a California car. Not sure when it was installed during the start of the PCV era. Note the inline push "thingy" in the rubber line. Actually ended up selling this valve cover and air cleaner on Ebay. What a way to spoil a great HEMI valve cover!! The oil breather on oil filler tube was untouched as well as the crankcase breather on back lower area was untouched so this seems only a weak attempt to satisfy the California bureaucrats. -----Original Message-----

Subject: Re: {Chrysler 300} Oil Breather Unit if I understand you correctly it is the normal pcv taking air for pcv from inside the main air cleaner mesh ( so air is very clean) and admitting it to the engine? sometimes blow by is sufficient to overcome the pcv and blow oil backwards ( pcv is not pulling air anyway due to no vacuum if your foot is in it ) and thus get the inlet fitting oil soaked , sometimes inside the air cleaner too . All that is kinda normal if ugly looking and the oil and air are clean . Pcv normal flow is very low it is not restricted by this . I’d leave it alone unless damaged or something ? A new one will be the same within weeks. That said and not sure it fits but I have a 78 dodge 318 pickup doing the same thing . Don’t like it — but way it is . Some fittings push into a rubber grommet and some have a 1/4 turn lock like an oil fill . I believe mopar performance sells them for its own valve cover line but may not fit ,— but must be common in junkyard ( Murray Park?) All production used this some thing years after california ? I wonder what year the pvc started ? A good thing , prevents sludge build up inside by pulling junk out . . Hot heads sells a kit to put pcv on 392 on the valley pan where the draft tube goes , I have used those on several cars at rebuild jkg Sent from my iPhone not by choice
