Thanks Alex. I wanted it to look as OEM as possible

While I do think the OEM CCV's functions work out great....when it works and if it wasn't located where it is then I would have had no desire to get rid of the damn thing. The only reason I hesitated to do this on my BMW sooner is because I am new to the BMW world and didn't know how sensitive the ECU/Stock engine management systems were. On previous cars boosted or NA I just stuck a filter on the valve cover and plugged the vacuum source. This is essentially what I did and with a good outcome. Although I never liked the idea of introducing crankcase gas/moisture/oil vapors back into the oil this was just a no-brainer.

Tomorrow I will work on installing a new O-ring for the dipstick tube as well as plugging the connection on the dipstick used for the CCV. And while I'm there might as well remove the CCV and proceed to smash it and its corresponding hoses with a sledge hammer.
