I have most of the components for this kit:

The canister they are using is the ProVent 200:

I don't have the catch can but can easily get one. Instead of getting the catch can, I was thinking of running the drain back down to a barbed fitting installed in the inspection bolt hole in the front driver side of the block.

7.3 Inspection Hole for Powdered Metal Rod Determination

This would make it self servicing instead of draining it periodically. It would also cut down on any oil losses.

Any reason not to have the engine re-using the oil that gets collected out of the crankcase vapors?

 

I can't think of any reason not to. If I'm not mistaken, the Racor system and Walker AirSep system for big diesels both send the collected oil back into the crankcase.

 

I know this is an old thread but would like to know if the drain back to the inspection hole worked?
My truck has the BD Crank Case Filter installation on it done by a previous owner. Remembering to drain this thing is a pain that I would rather not have. Returning the oil to the crankcase sounds like a great idea.
Anyone know of issues with this?

 

I never knew there was inspection hole there. Neat. My only concern would question how effective the flow might be. If the crankcase is pressurized at all, then gases would try to flow out that hole as well, while the engine is running, and might be enough to prevent your canister from draining, while running. So as long as your canister is a) large enough to store all the oil it collects, and b) capable of separating all that oil from the gases that are redirected into the turbo inlet, then you should be good, as it'll drain when shut off.

I think the problem with the original doghouse design is that the "strainer" simply filled up with oil enough that the droplets eventually would get blown into the turbo inlet after extended running.

 

I was wondering about the pressure as well. It would seem that the drain hose being much smaller in diameter would be more affected by the pressure than the larger hoses coming from the dog house.
Not being that experienced with diesels I am hoping someone that "knows" will chime in.
