No Smoking?

Great Dane:
Hope you don’t mind an ‘idiot question’ from a new arrival on the Series 3 scene. Bought my SWB 2.25 petrol (1980) last year. No hint of emission problems at the MOT, but now it smokes (grey/blue) quite badly after start-up, then settles down once the engine is warm. Haynes and other manuals seem to say this is always a sign of engine wear. Is that right? Could it just need properly servicing/tuning? Or be to do with lead replacement fuel?  If the engine is on the way out, what is the best option – new engine or trying to replace pistons/rings etc? Thanks.

If the engine is buring oil, get a new/secondhand engine and then take your time getting the old one rebuilt bit by bit.

Great Dane:
Many thanks.

Rich_P:
If the engine only blows out blue smoke on start up, it is probably the valve stem oil seals that are leaking.  This means when the engine isn't running, the oil in the head can drain down through the valves and into the cylinders.  When you start up, this oil gets burnt and gives you the blue smoke out of the exhaust.

If it is the valve stem oil seals, these can be replaced as they do wear and (I think) crack with lack of use or age just like a tyre.

Great Dane:
Thanks very much.
