Review on 🔧 GM 12567915 PCV Valve - Genuine Parts for Enhanced Engine Performance by Andy Mitts

Like the first review says it can be knocked out with a hammer oh there's a better way much easier to do this, but it's still the same end result compared to replacing the entire cap. Now you need to replace it if it's an old style cap but like me I have a new style but for some reason the PCV valve that was on it was bad and I didn't notice until the return period had expired. Definitely a new cover if you don't already have it, but if you buy another cover again you don't have to, just swap it out for this one. All I did was lay the valve cover on the floor, put 13" port blocking pliers on it, twist it, pull it up and it came straight out.
