Now that the wife's ML350 is fixed I want to address a pet peeve on my 83 300D. The air cleaner design sucks! I'm tired of replacing rubber mounts all the damn time. I would like to put a cone type filter directly on the turbo intake, and route the PCV hose from the valve cover into the metal drain tube that goes back to the oil pan, and ditch the damn metal monstrosity. Has any one done this? Can't be too hard, but part numbers, brands, links, or a DIY would be great. Thanks.
