PCV Valve symptoms are generally not "leaking coolant". In this video I will show you how a 3.0t Audi S4 failed PCV valve caused coolant to mix in the engine oil. I will also show you step by step PCV replacements for all 3.0 supercharged Audi engines. PCV failure is a common VW and Audi issue Thanks to @WD-40Brand for partnering with us on this video
