Hi everyone, I have just bought a discovery 2. The problem I’m having with it is if you leave it ticking over for a while (10 mins or more) then rev the engine or drive off it will smoke quite a lot. The smoke doesn’t last long (less than a min) then clears. The smoke stinks of burning oil and it is losing oil. It starts on the button in the morning without using the heater plugs and doesn’t smoke (sounds a bit lumpy for the first ten seconds or so). Drives great, pulls well and doesn’t seem to smoke much unless you leave it ticking over for a while. Hoping it’s not the rings. Any help or advice will be much appreciated.
Thanks,
James
 
hi mate, i had a similar thing with my 300tdi, started in a morning fine, just a little ploom of smoke, then cleared, and only when it was warm and i had been driving steady then backed off, i would notice a little smoke behind the disco, also as you say after ticking over for 10mins or so it would start to smoke, after investigation, i found it to be the turbo oil seals.
replaced it and never had any bother.
although a turbocharged engine should not be allowed to idle for more than 10 minutes, to prevent this sort of damage happening.
hope this helps :)
 
somthing else what may be useful to you mate ;

The Answer is in the Smoke
We can generally understand what is wrong with a diesel engine by the colour of smoke emitted from the exhaust. There are three basic colours - black, white and blue.

Black Smoke
This is due to a air to fuel ratio imbalance, either the fuel system is delivering too much fuel into the engine or there is not enough clean air (oxygen ) a few things to look for :

•Faulty injectors (injectors need attention at about 100.000 to 120 000 miles)
•Faulty injector pump
•Dirty air cleaner
•Turbocharger or intercooler faulty
•Problems within cylinder head, valves clogged up due to faulty EGR (exhaust gas recycling unit)
White Smoke
Normally means that the fuel injected into the cylinder is not burning correctly. The smoke will burn your eyes.

•Engine/pump timing out
•Fuel starvation to the pump causing the pumps timing not to operate correctly
•Low engine compression
•Water/petrol in the fuel
Blue Smoke
The engine is burning engine oil

•Worn cylinders or piston rings
•Faulty valves or valve stem seals
•Engine over full with engine oil
•Faulty injector pump/lift pump allowing engine oil to be mixed with the diesel
 
Sounds like its burning oil then mate, but it only takes a small drop off oil to pass the seals and drop into the exhaust system to give you a almighty cloud of smoke, id recommend, not leaving it on idle for prelonged periods, also take note over a couple of weeks on the oil level, take measurements etc, and see if it is burning alot, then it may be a little more serious than the turbo seals, but if it does not burn a deal, id look towards replacing the turbo.. but hold out a while before you replace as someone on here may have had a similar problem :)
