Good day to all,

I have just bought a 2001 Mondeo 2lt diesel with a duff turbo, I sent a second hand one up to be fitted by a friend, as he was not sure of the oil pipe flow / return he turned the engine over to see what one was pumping oil, both of us seem to think oil had gone into the exhaust pipe and may-be got as far as the "cat", when it was first run the smoke was so excessive I had to stop after a mile as the smoke blanked out the road, I found a back road and gave it some stick for a couple of mile and it seemed to clear a lot.

I took the car to a testing station about 8 mile drive away where it failed the emissions test, I dont think its the second hand turbo as the smoke was almost gone after the drive to the test station, if oil has got down to the cat, how would I clean it ? I did talk to a fitter at the test station and he said if it was oil sat in the cat converter it might burn off in about 300 mile but as the car has no MOT it's not possibe to do this, any idea what to do.

Many thanks for any advise in advance.

Kind regards,

Allan.

Get the MOT done on the car, you will probably have to replace the CAT, or you can chance driving it around to keep it clear but PC plod wont be too impressed if he pulls you with no MOT, and with a trail of black smoke, it would be a matter of time.

You could always jet wash the cat, but you would need to take the water to a specialist disposal unit, maybe your local tipping ground may have a "contaminated fluids" drop off point?
