When converting the BMW 6 cyl diesel into other cars the air box can be removed like this<\/p>\n

\"How<\/a>
How to cut a BMW M57 air box<\/figcaption><\/figure>\n

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,<\/p>\n

DONT FORGET TO REMOVE THE BREATHER FILTER !!! use the swirl cyclone instead of the filter.<\/p>\n

\"\"<\/a>this fits inside the breather on top of the engine, it replaces the paper filter that always clogs up.<\/p>\n

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.<\/p>\n

This is what we did.<\/p>\n

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<\/p>\n

looks like this in the CAD<\/p>\n

then we have it 3D printed and it arrives 6 days later and fits perfect<\/p>\n

the adapter bolts on , uses an big fat O ring to seal and 4 M4 bolts.<\/p>\n

note : do not try to glue up the hole in the crank case breather the oil will get through…everytime<\/p>\n

when the engine is in I will update with the pipes fitted.<\/p>\n
