I made a DIY to delete the PCV Diaphragm on my 440i using the Ross Racing Performance PCV Delete Kit. I walk you through all the different options that they offer and show how I installed a simple VTA kit on my car. I definitely recommend it to anyone that wants to avoid PCV Failure in the future. It's also reversible, so you can reinstall the stock pcv diaphragm/cap for yearly inspection if needed. Hope this helps.
