I am wondering something about my PCV valve. I have a 78 Cherokee w/ 401 stock/original motor.
The Haynes manual says the PCV is either inline or a part of the intake Manifold. On my intake right next to the EGR valve is a plastic fitting that fits through a rubber "Bushing" into the manifold. Is this the PCV valve or just a "bulkhead" fitting. There is no other device in the line from the fitting all the way up to the carb. If this is the PCV, Why can't I get it out? I have used everything but a come-a-long to get it out of there and it's in tight!
Any ideas? When I remove the hose nothing comes out of the intake side of the fitting. ( no pressure) I get real strong vacuum from the hose on the carb side.??????????? Any help is appreciated.
If it can't be done from the seat of a Jeep, it don't need to get done!
