Hi,
I have a 1.8t with a Ko4 turbo,
About 2months ago I noticed a high pitched whistle noise whilst driving coming from the engine, there was no change in performance,
however for the last 2 weeks or so my car has started kicking out a hell of a lot of blue smoke whilst on boost,
the car is really undrivable now,
was just wondering if anyones got any advice?
I was thinking that the turbo is knackered, due to a previous boost leak somewhere?
Many thanks!
