Hi guys.
Exhaust puffs out white smoke from start up and even when warmed up and been driven for a while.
It is not constant but it does smoke more than not.
Also the yellow oil light will comne on for 5 seconds a couple seconds after I have started the car even though I have topped up the oil, im not sure if this is a seperate issue.

Many thanks.

White smoke is usually indicates coolant is getting into the combustion chamber. That is usually caused by a bad head gasket. Check that first. Next, make sure coolant isn't getting into the oil. That could cause the oil light to come on and cause internal damage.
