can a turbo be fooked even tho theres no oil in the boost pipes just seems to smoke when it warms up after about 1min ?

 

I would be interested to know this aswell as mine is doing the same? When you start from cold it is fine then when it has been run for a bit it smoke blue smoke all the time worse if on boos i think but even off boost say in 5th gear at 70mph it is very visible... any ideas????

 

maybe a seal away in the turbo unit
