Surprised by this. My manifold was bone dry on removal, which could partly explain the goodi(ish) condition of the valves.
What I don’t understand is how such a large amount of oil could accumulate in the manifold. Normally, the oil could only enter the manifold via the crankcase breather in the form of a mist, the breather only delivers this mist when the engine is running and when the engine is running the mist should be sucked straight back into the cylinder via the valves.
Perhaps a compression test on each pot when it’s all back together?
A couple of things, 1 all the oil mist going into the engine is only true whilst the engine is running. When stopped and it cools down the mist in the manifold will drop out to be oil. 2, there is a pocket below the breather entry in to the manifold that will hold oil. 3, comprssion test, I hope the engine does not need that? But yes I could do one.

The oil level is always up to the high mark but never over.
I think it could be the oil I am using or the engine has been over filled at some time in the past.
