forgive my ignorance, but there's a tube going from my cylider head into the bottom of the air filter unit of the 32/36, is that a vacuum hose? regardless of what it is, i'm getting oil up in the air filter because of it.

i know it's not supposed to do that, so what's the deal?

It is supposed to do that. That hose routes excess oil blowby in from the head into the carb to be burned off.

a filter on the end of mine - or you can route it back into the carb like yours

If you're feeling ambitious, you can rig up a catch can to act as a separator, then run another line to carry the fumes to the air filter housing. This will allow the oil to settle in the catch can, while still pulling the fumes into the carb, not to mention keeping a vacuum pulling on the crankcase - probably overall the best solution. You will have to drain the catch can every now and again, however.

my 69 seriously looked like it had been professionally sprayed with undercoating, but it was all just dirt and BMW time-release rustproofing!!!!!

Sounds better on Ebay and print ads.
