Thanks for posting the question, RW. I'm sick of looking at those big stupid aircleaner housings but have been avoiding dealing with it until I figured out how to make an oil separator. I'll just skip it for now and see how it works.
Sold the '84 300D with WVO conversion on Ebay last week. Tons of hits - the WVO thing really drew some interest. Making new tanks for these two "new" cars now.
