BMW diesel M57 and M57 N engine breather 3D printed
When converting the BMW 6 cyl diesel into other cars the air box can be removed like this
If you are having a catch tank then the exit pipe for the crank case breather seen at the rear hanging down can be cut short and then blocked off in the round turret with a washer and two pop rivets, the hose to the catch tank comes out of the round lid,
DONT FORGET TO REMOVE THE BREATHER FILTER !!! use the swirl cyclone instead of the filter.
BMW part number BMW 11127799366
this fits inside the breather on top of the engine, it replaces the paper filter that always clogs up.
BUT what if you want it in a road car and still want to recycle the fumes from the crankcase well then such a problem arose in the latest conversion.
This is what we did.
cut the air box as in the picture then CAD a model of a converter to make the pipe run along the top of the exhaust manifold
looks like this in the CAD
then we have it 3D printed and it arrives 6 days later and fits perfect
the adapter bolts on , uses an big fat O ring to seal and 4 M4 bolts.
note : do not try to glue up the hole in the crank case breather the oil will get through…everytime
when the engine is in I will update with the pipes fitted.
Hello there
What material is it best to make this out of please ??
The original one I did was using Shapeways service in their basic cheap white plastic and it worked well. If I was sprinting it on my 3d printer I would recommend Nylon 6 or something similar that would take higher temperatures that can be under the bonnet.
Hi Beady i would need the 3d model for the adapter. Willing to sale?

Hi Thorben,
sorry for the late reply I have been away traveling in the desert.
Sure you can buy it from me, it is 3d printed by a company called shapeways
my shop is here.

Is it possible to buy this adapter from you? I’m searching some sort of upgrade for the oil separator.
Greetings
