I hope that this doesn't sound silly. I have a 18s the engine is a 1952 and the question is does the crankcase have a breather and where is it.
thanks for the help

Re: Crank case Breather
Left side of the engine in the crankcase behind the primary chain case. Its a bit tricky to get at. You often get a drip of oil or two from it after a run.
If it ain't broke, fix it till it is.

Re: Crank case Breather
The breather is the threaded port coming from the main bearing housing. There should be an adaptor screwed into it with a diaphragm on the engine side and usually a copper pipe and cap nut on the other. The pipe usually is bent and points down towards the ground.

Re: Crank case Breather
Many thanks and sorry about the late reply.
Can confirm that the breather is not blocked. but i have found that the crankcase had about 2 cup fills of oil in it.
Any suggestions to why and what i can do about it please.
thanks
