I'm returning my '74 Datto 180B SSS is to the road after an extended time in storage, and fixing a bunch of things I really should have fixed 20 years ago. One of the problems that's giving me grief is that the crankcase breather is open to air (the cam cover breather is routed to one air cleaner) The original breather tube is long gone and I haven't been able to find another. I do have a 200B breather that fits in the hole but sits all wonky so doesn't work.
I have an oil catch tank I picked up from Otomoto a while back (http://www.otomoto.com.au/p/5356051/kkr ... h-can.html
) so I want to install it and connect it to the crank breather. Apart from cutting and welding the 200B breather tube which won't be much fun as I'm not very good at welding, what's an alternative approach to getting a breather tube into the crankcase that won't fall out? How have others solved the problem of providing a catch tank?
