    Default Blown turbo= bad emmisions?

    A few weeks back the turbo failed on my 2.2 dti. Nothing major happened just a loss of power and a slight screech from the turbo. Got the car home and found the impellor bearing had collapsed, the impellor was still intact both sides just scraping on the turbo body. Replaced the turbo with a new one from vauxhaull and also removed and cleaned out the intercooler although there was next to no oil in the intercooler. I always keep an eye on oil level and i know she was basicly at the max level when the turbo went. When i drained the old oil out i collected approx 4-4.5 ltrs of oil so she had put approx 1ltr of oil down the exhaust give or take a couple of hundred mls. once i fitted the new turbo i took her for a run and she was pouring smoke out the exhaust for a good distance until she started to clear. For the last two weeks she seems clear with no smoke but she still gets thick oil hanging around the tail pipe, She's due a MOT in 8 weeks time. My question is, will this oil lingering in the exhaust affect the emmisions test? I plan to put some cataclean through her to help aswell.
    Sorry for waffling on a bit.

    Cheers

    Diesels get a smoke test not an emmisions test. If there is no visable smoke then you should be fine
