Help blocked crankcase breather

Does anyone know where to find the crankcase breather on a 2 litre twinspark 164? - i think it may be blocked as I am getting oil in the air filter

There is a cylindrical oil separator (black in colour) mounted on the inlet manifold near the idle speed controller. It has two large hoses and one small diameter hose attached. The small hose drains oil back to the crankcase, it is almost certainly blocked.

I had a similar problem and found small dia hose that returns to lower part of engine was blocked and had started to go hard so it is probally worth replacing
