Where or how does my 1959 C15 breathe from the crankcase please ?
I know my later side points C15 breathes through the camshaft and eventually out of the breather pipe near the clutch cable arm.
But I can't see where my distributor engine breathes via or from to the atmosphere.
Hi Richard,
It breathes thro' the camshaft into the space between the inner and outer cases, there is then a small, semi circular, cutout on the rear of the outer cover to vent to air.
Any oil is trapped between the cases and returns to the sump via a pinhole low down in the inner case. This hole is critical apparently and must not be enlarged!
At least that's the theory!

Super
Many thanks
