Review on 🔧 PCV Valve Kit for BM-W E46 3 SERIES E39 E60 X3 X5, Positive Crankcase Vent Valve Breather Hose, PCV Crank Case Ventilation Oil Separator Hose Set 11157532649 11611432559 11617504535 11617504536 by Bob Randles

I only bought this to get the hoses when I was rebuilding my old OEM CCV valve with a new diaphragm. I had to remove all the red o-rings and replace them with old hose o-rings because the red ones are too thick. They generally almost don't kick in with a lot of effort and lubrication. Also, the CCV valve included in this kit has been opened up to compare to the OEM I rebuilt and the holes for the atmospheric pressure side of the diaphragm are much smaller here. It almost looks like this could cause a problem at high vacuum levels, but can't confirm it as I haven't tested it. In general a good kit, just change the rings, the fit is fine.
