Hi everyone, I have an idea that I would like to run past the group. I recently did a very elementary ccv delete which consists of a direct hook up between the vacuum port of the old ccv and the valve cover vent hook up .I included a generic pcv valve in line. This set up eliminated the oilcoholic personality of the m54 , However it creates a strong crankcase vacuum. I want to relieve the excessive vac. by cerating a ingress vent through the oil return port on the dip stick tube by routing a hose from that port to the air breather I dont know if this has been tried yet or not but any feed back would be welcome. I suspect some one has Already tried this. I may try this this weekend.
