After working on my car, I didn't bother to reattached the line from the pcv valve into the air intake before testing the motor. It ran normally. This made me question whether I need to even return it into the air intake.
Basically, can I run the hose from the pcv valve into a can or some filtered holder to collect oil, filter fumes or anything else coming out of the case? I would then cap the opening on the intake.
If doing the above is safe, would it actually help my engine run better? My logic as to why it might help, is it removes any oil that may otherwise go through the motor.
