Hi Elie, The problem as I perceive it is one of space, there appears to be no way of routing the crankcase breather into the side of the rocker cover because the inlet manifold, distributor and heater take up the space. I cannot route into the front of it because the water "tower " is there. I think it impractical to go into the side above the exhaust manifold(?), so that leaves the rear. This can be done but it would be directly below the filler cap which is where the pipe to the catch tank is connected, so the oil from the crankcase will simply blow straight out into it? A more simple solution would seem to be to vent the crankcase directly into the catch tank, but i am under the impression that a heck of alot of oil get thrown out from it. Or am I mistaken in this assumption?
