any suggestions??

cheers lro jr

When you say "it blows a fair bit more in first gear", do you mean; every time when you take off, or only the 1st time after a cold start.

If only when the engine is cold; white smoke is unburnt fuel and is not a concern if it occurs when the engine is cold.

If every time; grey, or bluish grey smoke (which might be confused for white smoke) indicates oil is being burnt - worn piston rings or valve stem seals. This smoke will be seen even when the engine is worn, and when the engine operation has allowed significant oil into the combustion chamber.
