Seek no further:
I just took of the top of my mk II. The valve stems were stif and britle, and the hole for the stem was quite a bit lager than the stem. So oil is sucked down via the inlet valves, as there is a vacuum in the intake. I suppose some years of the the TDM had some bad batches of seals. Anyway, mine doesn't use oil now. Did a valve job and a hone at the same time, but the valve stem seals were deffinately the culprit.
