RE: {Chrysler 300} Oil Breather Unit



To answer John’s question:  PCV valve was factory installed starting in 1961 models in California only and starting in 1963 models for all 50 states.

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?
