So my ranchero has a PCV system on it and I wondered on the passenger side there is a tube that comes from the valve cover into the air filter housing unit. Can that be removed and have a filter put in the whole in the valve cover or does that tube need to be present to the system.
Yes and no.. Do you have to pass emissions testing? the Tube dose 2 things it allows filtered air to be drawn into the motor for the PCV and it vents the excessive blow by into the combustion chamber to be re burnt So yes you can eliminate it with a breather cap but it is not smog legal
Passenger side? Your PCV system maybe different but that is where my PCV is located and the hose to the air cleaner is from the filler cap on the drivers side. Regardless 5.0 is correct about the hose that connects to the air cleaner.
On mine, there's a hose between the passenger side rear and the passenger side of the air cleaner where inside there is a sponge filter and another hose between the drivers side front PVC/oil filler cap and the rear bottom of the carburetor. I don't know if it's correct, but that's how it's been hooked up since I've own the vehicle.
Alright, and no I do not have to pass emission testing. Thanks guys. I just didn't know if that hose completed the system and kept it in a vacuum or something.
