pegleg66:
Many thanks for your ideas, finally got around to looking at my disco, took off whole manifold with turbo attached, well when looked at the cast section of the rear of the turbo there was a hole in it, therefore air mixture all wrong drawing more fuel and puffing out black smoke, just gotta put it all back together now.
thanks again

well i have now replaced head gasket, cambelt and manifold part of turbo as it had a hole in it, cleaned out intercooler and plenum chambers with solvent, it's smoking when idling and when you put your foot down a large plume of white to grey plume of smoke comes out of exhaust, was driving not to bad, will idle excellently apart from said smoke but when i just took it for a run again it lost top end power and there is oil around the turbo top oil feed bolt and over the down pipe of the exhaust, i have been running just to get rid of the smoke thinking it was just the solvents that i cleaned the intercooler with. but car has been left idling for an hour and twice been driven till warmed up to no avail. is it the turbo ?????.

Range Rover Blues:
White acrid smoke is retarded timing, sometimes caused by blocked fuel filter.

If the turbo isn't working at all the car should just be lame, no smoke as the fuel pump won't fuel up till it has turbo pressure along the little black pipe

But the oil leak doesn't sound good.  check and see if it's dumping oil into the intercooler pipes.

Piston rings? May have gone before all this started?
