Oil Geyser (in my engine compartment)

1984 300d turbo, 417k, capable of 114mph, stock aside from K&N and advanced timing.

Hey folks,
Having a bit of an issue with the line that runs from the oil-breather (valve-cover atmospheric) down to the crank case nipple (behind the turbo nipple).

Background: I installed the www.wade************************ Stage 2 kit for the 300d, which consists of a K&N type filter, the proper intake pipe (mounts to turbo) and a replacement oil-breather unit, complete with catch tank and hoses.

Well, I didn't quite install the breather kit, as I discovered that the line that runs from the breather back to the crank case was dislodged from the crank-case. Yes, my engine bay is a mess now, but it gets worse.

Last night, I just ran the blow-by tube to a catch-can that I made out of a heat-proof receptacle, thinking that the mess was coming from there. That worked just fine, however, the line that goes down to the crankcase (with nothing feeding into it) geysered all over the engine bay, and onto the turbo. Not cool.

So, I guess I'm wondering if the metal oil-breather (return to crankcase) line requires the pressure coming from the valve cover to prevent itself from spewing oil all over the place. Or, is there another factor causing the oil to blow.

I'm worried that if I get the propper o-ring on the crankcase nipple, and route the line back into the performance breather kit that I have, that I'll be either 1. spewing oil all over the road, or 2. spewing oil into the intake tract via the optional port on the intake.

Can't I just cap the nipple, use a catchcan for the blow by (minimal) and call it a day?

Thanks in advance.

A pic of your setup would help. I have a similar one on my 300CD, although I just got rid of the el cheapo catch can and oil seperator that came with the kit. They just melted and started leaking, pure junk. I got rid of the catch can completly and threw out the oil seperator, replacing it with an external seperator from a 82-83 240D. My rubber mounting piece from the intake to the turbo is deteriorating fast so I'm on the lookout for a replacment for it too.

I think you're referring to the drain tube that the air cleaner housing used to sit on? Mine too will blow oil back up out of it if left uncovered. You need to have your seperator sitting in it, with a preferrably new o-ring.
