I'm still deciding how I'm gonna collect that nasty, oily blowby. I don't like the idea of it going right back into my intake elbow and making a mess of the elbow and the turbo impellor like the stock setup.

Also, what did everyone do with the drain tube back down to the pan?

If the temp differential was actually negligible, MB and every other manufacturer wouldn't have made every effort to draw their intake air from outside the engine compartment. MB even made their own specially vented fenders for most 124 diesel engines exactly for this purpose.

As for a catch can, I soldered in a nipple onto the turbo oil drain in order to re-route the captured oil back into the pan. I used a good old fashioned 240D catch can. Try this for a sleek alternative

and they put the air filter assembly right smack dab on top of the turbo which can get so hot that it glows red & white, but oh, that's not heating the intake air. *rolleyes*

I was reading about diverting some of the blow by oil into a cannister and then read that the the stock air box has kind of a turbo separator that spins the oil out and puts it back into the crankcase. Sounded like a good idea.
