Am I correct in thinking that muck on valves is less of an issue on the Duratec engine?

No the issue is as there is no fuel in the air going through the valves the petrol being directly injected into the cylinder like a diesel. This means crankcase gases with oil flow over the valves but unlike in a standard petrol engine they aren't was off by the fuel in the fuel air mixture. Hence the concern.

To answer the question more directly...yes, it is less of an issue on a Duratech. For the reasons John stated above, though a slight typo...he meant to say the backs of the valves aren’t “washed” by the petrol/air mixture as it flows past into the cylinder.

Correct I meant the back of the valves on a GDI. Sorry for the confusion.

Well, after only ~200km, there was a good shot of oil/water/exhaustgases in the catch can, clearly it does catch a lot of stuff.
But the YouTuber "Humble Mechanic" had those sent in to a specialist who analysed the liquid, and it was to a very high degree just water.
So, I am considering venting to atmosphere through a breather as well now...
