Dad's disco is smoking badly but intermittant ?

(1/3) > >>

cardiff_gareth:
Dad reported to me today that his Disco is playing up, it smokes really badly, especially when cold but only for about 5 minutes then it settles down and stops as if it never happened ?
He says its blue smoke, like the head is gone but the temp gauge is fine and its not overheating. Its so bad that you can't see behind for the smoke  :shock:

So what could cause them symptoms, I though blue = oil and if not overheating then poss Turbo but thats a stab in the dark.

If it helps its a 300tdi

Cheers in advance guys  ;)

team_wingnut:
mine does it when cold, its got 142000 on it, its either turbo, stem seals or its drawing air in the fuel somewhere, mine will misfire a little bit when its cold too!

My Td5 Disco is the same, was told it was the air flow sensor, changed it and it made no diff at all  :doh: not sure if the 300 had one of those though?

it sounds to me mate,that the turbo could be knackerd,what happens is,the seal in the turbo lets oil into the exhaust,it heats it up,and burns,hense why it is smoking bad,it only stops after a while,because it has burnt off what was in the exhaust,just a thought :-k

might be the valve guide seals, mine was like that before i feplaced the head gasket etc :( :( :( :(
