I lost all of my confidence in the bmw ccv with this engine,so I will never go back to it.I definately don`t like how the ccv system is hooked into the lower part of the dipstick tube. almost a year ago is when I had a hydrolocked engine because of the ccv failure ,sucking oil from the crankcase through the lower dipstick tube hose.
