Re: {Chrysler 300} Oil Breather Unit



Ron, John, et al,
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.

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 
Good luck !

Hey folks,
My 1965 Chrysler 300 originates from South San Fransisco, CA.  As a result, it has a connecting hose from the air cleaner to the valve cover breather element, and the element has a nub to attach.   I cannot find this breather with the nub marketed.  While I have soaked the breather element in cleaner, I am concerned about how well it is working.  Any ideas or known manufacturers for this element?
