Nice setup, I would love to have that on my 240d it has nasty blowby.. The only problem I see is it blocking the view of your VNT in there . That's the 240DT you have on youtube isn't it?

Pardon my ignorance, but why is the oil/water separator necessary?

Oil/Air separator is to allow most of the crankcase ventilation oil to return to the crankcase rather than being burned. Rather than modification, the easiest route is to install new o-rings on the bottom and seal around the cap of the separator with RTV. It makes a world of difference.

Unfortunately the above is not the only issue. If you have enough Oil Vapor inside of your Air Filter Housing (on my 84 300D the Blow-by is channeled into a Separator that is in the Air Filter Housing) that the Separator cannot handle you find Liquid Oil in your Housing and that the Vapor saturates part of your Paper Element Air Filter; shortening the life of the Air Filter.
So the goal of some mods is to condense Oil Vapor back to Oil and return it to the crankcase better than the Stock Oil Separator; and at the same time keeping Liquid Oil out of the Turbocharger and Intake Manifold.

This represents my effort to do so:

Sealing around the top/cap of the oil separator has virtually eliminated the oiled air filter issue for me and the cost was pennies.

I made my oil/air separator from 3" plumbing fittings...a cleanout and a cap. Fittings tapped in and a bracket welded up. Seems to work good.

Nice work...

I think the 'blow-by' issue, at least in most cases, is simply normal vapors leaving the cam cover and picking up the oil spray....Robert

Ok so heres the deal. I plan on dropping a cold air intake on my pretty much stock '84 300SD (other than EGR removal). I've been told that they run best with a wee bit of vacume applied to the crankcase. Truth? I'd love to have a set up like Brads. where could i get a separator and what not to make this happen? Any tips would be awesome also.

So when my air cleaner mount broke for the second time I said.. many expletives, then I thought of what I could do to get rid of the darn thing altogether. I have added pictures of what I did but essentialy, it is what everyone else who has done this did:

Just take the fittings off the top of the oil separator by bending back the tabs.
Find a suitable can (a can of baked beens fit PERFECTLY), so I didn't have to bend edges, or make tabs, just open can, eat beans, clean, ready to go( in reference to this guy)
Bend the bottom to make it kind of domed-ish (courtesy of a hammer and a wooden stick)
I cut the drain tube off the original oil seperator (courtesy of a hammer and a screwdriver to "cut" through the metal)
Punch a hole in the bottom of the can, put the drain tube in, RTV Silicone it in place.
Fill can with stainless steel wool.
RTV silicone the top on, use pieces of garden hose and 1/2" CPVC that I had lying around to connect it up....
Then I just caulked the whole darn thing in place with some more of the Oil resistant RTV silicone.... I was going for cheap and easy, and I'll tell you, it works VERY VERY well. I didn't think it'd actually hold on, but I gotta tell ya... that sucker is ON there good, while still flexible, so I can laugh at the idea of breaking more brackets instead of replacing my motor mounts

Total cost $1 ish (worth of silicone, I bought a caulk tube of it for 8dollars)
I'll try to be updating how it is working... Note: The outlet tube should not be vented to atmosphere, I just wanted to see how much oil was coming out the outlet, to see whether I have more work to do getting it to take the oil out better before I hook it back up to the intake.

Yeah... but how much did the beans cost?
