Ok,went to start car this morning,no smoke on start up.After about 5 mins it started to smoke.i did change the standard breather setup to a bailey breather 3 weeks ago thinking that this may help but it didn't much.tommorow I will do a compression test as Karl suggested but I am also thinking it could be the turbo?i put the car back on the road late last year after it being stood for over 4 years.
