Review on 🔧 GM 12567915 PCV Valve - Genuine Parts for Enhanced Engine Performance by Anthony Gupta

This part is designed to fit the newer 2005 and up 5.3 liter engines found in most Tahoe, Silverrado etc vehicles and pressed those little parts into the valve cover! But you can "gently" tap it out with a hammer if replacement is needed. Removing the valve cover is a must for access and I recommend cleaning the oil crust from the inside of the valve cover. Also, screw the hole just below the PCV valve to 5/32" to allow excess oil to drain back into the head and keep the smoke plume from reappearing. My life hack that will help you not to buy this new cover for a small amount. Welcome back;)
