Hi i was jump starting my nieces disco today after fitting a gearbox in it and i was getting a lot of blue smoke and it smelt like unburnt fuel and it sounded like it had a miss fire coming from the tail pipe i dont have any blue smoke when driving or any miss fire i was thinking it might be an injector doing down
-
could be knackerd diaphram in the pump letting it over fuel it,or like you say an injector down :-k

sounds like my disco ! new brakes, new rad, new bushes, new shocks n springs, now water leak back of head !, and dont get me started on the welding iv got to do :doh: it never ends lol
-
it is a never ending job on disco's if i never spent so much cash and time i would of scrapped it
I keep thinking that....and then thinking if I has scrapped it ages ago I wouldn't have to keep spending the money....but I would just buy a replacement....and that would need loads of money spending on it...so I figure its better stick with the one I know

Hi.
Blue smoke would indicate oil being burnt, excess unburnt fuel would give you black smoke.
The slight misfire could be linked to the oil burning, both could be caused by a failed or failing head gasket.
For oil problems also check the engine breather which often gets ignored, but this wouldn't give you a misfire so you may have more than one fault.

I reckon it could be your lift pump or valve stem oil seals,I would try the lift pump first as its cheap and easy to do,I would then do the stem seals again cheap but real fiddley to do with the head on so im told.
