I was following this advice until I went to Moab & a brand new PCV failed. Second time this has happened to me...first time with AutoZone brand. I took out a perfectly good one before the road trip and put in a new one only to have it (the new one from Advance Auto--Purolator) stick closed.
My engine which usually is very good on oil usage (like 1/4 quart in 3,000 miles) sucked up one quart out of the blue. Caught it when I refueled & checked oil. Than saw oil spray coming out of my breather cap (aftermarket).
My new approach is to just leave a functioning one in and check periodically for any oil spray from breather cap & check dipstick @ fuel stops plus when putzing under the hood. It looks like my set-up allows the excess crankcase pressure to exit out the breather cap (if PCV is stuck) when normally it would be sucking air into the breather cap. I'll carry a spare PCV from now on and be reactive instead of proactive!
