Mercedes OM617 Powered 110 Build Up

Crankcase Ventilation.

The OM617 vacuum pump brings in forced air to vent the engine.
This is often confused as excessive blow by.
On the 110, I used the W115 OM617 inlet manifold with a Land Rover TDI intercooler.
At the time didn't have a catch can, so I cut the stock unit out of the OEM air cleaner and ran plumed it into the 1993 Chrysler New Yorker Air Filter.
The catch can has 3 hose fittings: one for the valve cover, one that goes to the inlet side of the turbo, and a drain to the oil pan.
In theory, the oil vapor condenses in the catch can and drains back into the oil pan sump.
Any excess oil vapor is sucked into the turbo and ends up getting burned in the engine.
Since an internal oil coating reduces the efficiency of the intercooler, I mounted an air compressor liquid trap between the catch can and the air cleaner.
The fitting for PVC on the air cleaner housing is below the air filter element.
The limited vapor getting to the air cleaner housing gets sucked through the air filter element and leaves it black requiring it to be changed more often.

I am working on a larger catch can with 3 chambers separated by a divider.
The shape is cylindrical with a divider down the middle that doesn't reach the bottom.
One side at the top will have the inlet, the other side will have the outlet.
Part way up the divider will be a have circle of perforated aluminum that screws to a bracket attached to the center divider.
Each side will be filled with course stainless steel wool.
The vapor and air under pressure will enter one side travel through the stainless steel wool, go through the perforated aluminum plate, travel around the lower part of the divider, go through the other perforated aluminum plate, travel up through the stainless steel wool, and out the top.
There will be a glass bowl on the bottom with an aluminum bottom identical to the custom sedimenters.
The lover bolt will have a drain to goes down into the oil pan sump.
The outlet will be attached to the turbo inlet close to the turbo.
The fresh air will be pumped into the engine by the vacuum pump, go out the valve cover into the catch can, out the catch can and into the turbo inlet along with the air sucked through the air filter.
The oil will deposit on the stainless steel wool on both sides of the catch can, drain out into the oil pan.
