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.

... the garage put 5-30 fully synthetic oil in ...
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! :rolleyes: You are wiser than the garage Martin for using 10W40. Maybe do your own oil change next time? ;)
