Review on 🔧 High-Quality PCV Engine Cylinder Head Valve Cover for BMW 128i, 328i, 528i, X3, X5, Z4 (2006-2013) - Compatible with N20, N26, N51, N52 Engines by Martin Masaniai

My original PCV cracked and caused a small vacuum leak. I had to cut the old PCV off (thanks BMW) but once the old one was off it was easy to put some RTV on top of this new PCV and press it in place. I let the RTV dry overnight. I started the car this morning and the engine is noticeably smoother and there is no vacuum leak around the PCV fitting so everything seems to be sealed properly. It was a lot cheaper than replacing the entire valve cover.
