Recently I was doing some maintenance on my car with another E46 enthusiasts and he dropped a knowledge bombshell on me. He told me that you can connect a small vacuum hose to the open port on the pcv and run it to an unused vacuum port on the back of the intake manifold to increase the amount of pull the system has and reduce the amount of oil consumed by the engine. I checked into this and tried it myself. It's reduced my oil consumption to half of what it was.

All that is involved is moving a few intake boots and connecting a vac hose. The small nipple that is usually capped, you can see it in the attached picture, is your port. The back / under side of your intake manifold will have several capped vac ports, too. Use one that matches the size of the port on the pcv and connect them.

It has seemed to work on my car and would like to hear how it works for you.
