No Smoking?

muddyjames:
but dont all cars have smoke out the back when the engine is cold and it is cold outside?

hobbit:

--- Quote from: "Steel" ---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.

not so much wear as perish to harden up an break, does your machine give of a puff of smoke when pulling away from standing at a junction or lights?

thats condensation

muddyjames:
oops. ignore my post then!

Great Dane:
Thanks to one and all for your useful ideas and suggestions. I reckon the smoke from my Landy's exhaust after start-up is definitely more than condensation (but it's true, that does happen on cold days), but I didn't know anything about the valve-seal thing, so many thanks. I'll check that out. If that isn't the answer, I guess I'll be looking for someone with a better engine to sell. All the best. :D
