Thanks Arvid. I have read your post on the subject before. Quite amazing.

I will try the same experiment, but I suspect it is not the same issue. You mention smoke in your post, and I can imagine you would have a fair bit.

I don't see any smoke, just the smell. There is a little smoke haze under high revs and full power, and I suspect the valve seals or guides as the cause of this. But I can idle forever and there is no smoke. Same going down hills.

I just get an aroma that smells like the fumes from the oil filler hole, and it goes away when the car is hot.
