I got a few questions, well 2, wats so special bout that lil breather thats connected to the PCV, I mean how come sum ppl put oil catch cans? is one better then the other? or diff advantages/disadvantages? An wats Das talkin bout when he said breather valve?

 

the pcv valve is the little rubber or plastic tube that come out of the valve cover and hooks to the intake manifold....there is a little plastic elbow on the hose that has a ballbearing in it...thats the valve

the little breather filter hooks onto the metal vent hose nipple on the valve cover...there would normally be a hose there that connects the valve cover to the bottom of the stock intake tube......

most cold air intakes and custom ones dont have the inlet for the vent hose on the valve cover....thats where the little breather filter comes in.....

a catch can is usually used on turbocharged engines......under high vaccum pressure the engine can suck oil out of that little valve cover vent valve and into the intake tube....the oil catch can goes inline between the valve and the intake tube to catch the oil before it gets into the intake......

the pcv valve has nothing to do with that little breather filter, or a catch can....and unless you put a turbo on your car, you shouldnt need the catch can

 

True you don't need an oil catch can, but they do help. I know some people who have installed one on their neon and it does catch some oil. The 95 neons had an oil seperator come stock.

 

Did they I have never noticed one on my 95 acr??. Where would it be ??.

 

It's only on SOHC engines and the PCV valve attaches down to the oil seperator box then goes out and vents the crank case pressure that way.

 

^the little box thats under the intake manifold???

 

are you guys talkin about that piece that if you make the ghetto cold air intake you have to either cut a hole and connect to it
or some people put hte tiny air filter in it?

 

Thats it.

 

i never knew what that was on my old 95....so when i stripped a bunch of 95's down i kept them all.....but later threw them away since i dont plan on ever getting another 95....i think a catch can is one more thing i have to put on my list

 

Thats the valve cover breather, not the PCV valve.
