I think that you would have to be very inattentive and have an engine with significant blow-by to loose enough oil to cause engine damage.

My airplane separator is working fine after several hundred miles. There only the slightest oil film in the intake vent tube.

Yours appears to be correct.
My concern is for those who fail to understand the routing/function of the air/oil seperator/crank case vent.

Several members have:
#1. Plugged the CCV and drain tube, this caused seals to blow out, thus massive oil loss.
#2. Connected the CCV and drain tube with no vent, this caused seals to blow out, thus massive oil loss.
#3. Plugged the drain tube, and dropped the CCV down the back of the engine to drain on the road.

In a month, I've collected 3oz of oil from the crankcase fumes. Even still, I have run without ANY oil separator, just a tube going straight to the atmosphere/road for over two years with NO problems.

I very much doubt I would (or could) run my engine dry of oil if any of the tube s come off.

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.
