My mgzt-t 1.8T smokes on start up from cold. Give it a short while and it stops smoking. What could be causing this? Is there a PCV valve on the k-series? It had a reckon head not long back.

What colour is the smoke? Blue? It could be leaking valve stem seals.

My 1.8L sometimes does this, I think it is because the garage put 5-30 fully synthetic oil in at the last service, noticed that as it uses oil and I top up with 10-40 semi synthetic the problem subsides. Only smokes on start up on very hot days, no problem this time of year.

5W30 is actually listed for the 1.8 non-turbo engine but for climates where temperatures fall below minus 30 degrees C. It's therefore not the best choice for the UK! You are wiser than the garage Martin for using 10W40. Maybe do your own oil change next time?
