Can you run a crankcase breather without a catch can?
Didn’t use a catch can. The rise up in the hose allows the engine to breath but not puke oil. Any oil that pools in the hose, goes back in the top end when it’s not running. At least that is the theory. Now if you don’t do the upward direction with the hose, a catch can will can the oil that normally goes into the intake.

What is the Positive Valve on a crankcase breather?
The PCV valve (positive crankcase ventilation valve) is a crucial part of the system as it controls the flow of crankcase gases entering the intake system. Both were as good as new. The electric connector sat in tightly and was free of rust and filth. Also, the hose was in good condition and was gunk-free.
