We have had problems with the cossie for a while
started her yesterday and runs quiet and fine but once warms up smoking when you rev the car on idle it is fine
but if leave running for 20 mins or so and blip the trottle
will puff our smoke then will clear it also has had problems with boosting any idea please ?????????????

 

Possibly worn or hardened valve stem oil seals,what colour is the smoke?,does the car drink oil?,if you leave the car overnight and re-start it the following morning does it smoke?.

 

it doesnt drink oil uses abit but not more than mayber half a litres 500 miles if leave over night and start doesnt smoke on start up just taken turbo downpipe of no oil ???????????????? help
