Ok thanks any idea on cost to get repaired..?

If your pulling it apart you might ask yourself is it worth changing crank rods and pistons. Couple of grand to do all that. Is it worth changing rings then have the crank go later on?

how bad is the smoke ?? if using less than a litre of oil per 1000miles dont bother. saying that you might have fun and games with emmissions next mot . the chhep option and poss half cure is to fit a oil catch can

if its blue it can be a number of things it can be turbo seals or the stem seals or piston rings and fitting a oil catch can will do nothing for the smoke or emisions really as the oil is getting in after the intake stage the cheapest option is the turbo and if its not the turbo it will be cheaper to buy a second hand engine from a breaker on here.
