Hi, my 200TDi Defender smokes quite bad on start up. I realise this is nothing unusual but it seems to be getting worse. Before I changed the engine oil it was black smoke, now with new oil it's grey and almost white. Is this likely to be just the valve stem oil seals wearing out?
If so, is it a fairly straightforward job to take the head off, valves out and change the seals?
Cheers, Dave.
