Hi all


We have a 2002 disco facelift td5, just had a new head ( pressure tested) and done 1000 miles. had to tow it back to the house after a breakdown only to find 15 liter mix oil + diesel in the sump . we have changed the injector seals thanks to the great guide on www.discovery2.co.uk . it idles very poor and we have smoke from the back of the engine bay.

i know this is a bit much but please can we have some ideas
(and no, i have already been told to let it burn )
