I had to put on my plumbing hat for this job.
I started by building a bracket to hold a breather filter above the transmission.
I then scoured my garage for all sorts of tubes, hose, fittings etc…
I was able to piece together a connection that ran from the crankcase breather outlet to the filter.
Unfortunately, the angle of the crankcase breather outlet aims outwards towards the right side of the engine. I test fitted the custom starter cover before I added all the hoses but once the hoses were added, the starter cover wouldn’t fit. I tried shaving down the edge of the hose but it wasn’t going to work due to the angle of the breather. If I forced everything together, after time, the vibration of the the parts would have damaged the fiberglass starter cover.
Luckily, there is a later model breather that has the exact same footprint but the outlet aims upward.
Then it was just a matter of connecting new hoses.
I cut down a new BMW crankcase breather hose meant for this style breather.
I also made a trip to my local hardware store and found a brass elbow fitting to connect with the filter.
I had a small tray fabricated out of aluminum. I placed it under the filter and connected it to the top of the transmission using the original air filter retaining bracket’s bolt hole.
I don’t anticipate any oil coming from the crankcase breather for many many many miles to come. But should the engine start to weep oil from the breather, it will get caught in the trough and not leak onto the transmission.
It isn’t the prettiest plumbing job but it will work and luckily it will get covered up by the starter cover.
