delburt0 Posted October 10, 2013 Report Share Posted October 10, 2013 (edited) It's called a diesel, wouldn't worry about it unless it's doing it constantly in every gear ,I once stopped the traffic on the m1 with my shogun.

sishyplops Posted October 11, 2013 Report Share Posted October 11, 2013 (edited) I just lifted this off the merc forum, these are the responses to a guy asking "what colour is unburnt Diesel?" this is what 4 different peoples opinions look like "un burnt diesel has a grey/white/blue colour and a distinctive sickly smell,""Unburnt diesel will be black, ""Unburnt diesel appears white. Poorly burnt diesel appears black ""I would discribe un burnt /poorly burnt diesel .... white or pale blue colour, not as blue as burnt oil though." Below is the response I agree with, I was a forklift engineer for many years and I believe this to be correct from ChrisBrad66 on the MB Club Forum (i hope he doesn't mind me lifting it ) you only get black smoke when your air filter is blocked or some other restriction on the induction side,causing a rich mixture, i.e. too much fuel and not enough air, bluey white smoke is unburnt or poorly burnt fuel. However a small puff of smoke every now and then when you accelerate could just be the exhaust clearing itself out, all diesel engines will do this now and again Edited October 11, 2013 by sishyplops Quote Link to comment Share on other sites More sharing options...
Twistedsanity Posted October 11, 2013 Report Share Posted October 11, 2013 As an ex plant engineer (diggers and dumpers not Daisy's and pansies) black smoke is over fuelling or Unburnt diesel , white smoke is water so indicative of a head gasket problem and blue smoke is oil leeching past the piston rings and burning. Black smoke suggests changing the air filter, checking the cold start system isn't stuck on or could be a lazy turbo on the way out and the carbon build up inside it burning off when you boot it and it spools up and gets hot Quote Link to comment Share on other sites More sharing options...
karpman Posted October 11, 2013 Report Share Posted October 11, 2013 Build of **** in the exhaust give a good boot up the road. Have to do it before we stick em on the emission reader for the mot. My misses eco4 has long gears to and revs low should see the cloud that beauty puts out when ya boot it. Karpman Quote Link to comment Share on other sites More sharing options...

thepasty Posted October 11, 2013 Report Share Posted October 11, 2013 (edited) due to fuel costs I drive my old 3l hilux surf like driving miss daisy so when I boot it out of the norm theres one hell of a smoke cloud.... doesnt worry me Edited October 11, 2013 by thepasty Quote Link to comment Share on other sites More sharing options...
Traztaz Posted October 11, 2013 Report Share Posted October 11, 2013 I think you will find the above incorrect, its probably the valve stem seals, they become hard and do not seal anymore, this allows oil to drop into the cylinders, causing black smoke. More often than not black smoke is oil in the cylinder, not un burnt fuel. Quote Link to comment Share on other sites More sharing options...

More often than not black smoke is oil in the cylinder, not un burnt fuel.Thats odd! When I see a vehicle that blows it's rings it fills the road with a dense cloud of blueish smoke! Not black. Infact I remember an old girlfriends son topped the oil up in her car once! A whole 5L can and when she started it, the whole street filled with blue/white smoke. The oil was being forced past the piston rings and directly into the cylinder. When the valve stem seals went on my cars the smoke again was blue! The ONLY time I ever had black smoke was down to the fuel air mixture I have never seen a car spew out black smoke because the valve stem oil seals have gone or because there was oil finding it's way into the cylinder Edited October 11, 2013 by Lord Geordie Quote Link to comment Share on other sites More sharing options...
Kes Posted October 12, 2013 Report Share Posted October 12, 2013 (edited) I suggest it may be the injector adjustment - too much fuel for the air mixture resulting in unburnt fuel and 'black smoke'. Air filter check first (as others have said), check pipes for restrictions etc. it could simply be a tweek on the EMS and if you car is a well known type, a 5 min diagnostic will sort it.

00buck Posted October 12, 2013 Report Share Posted October 12, 2013 check the air filter and the egr valve and clean out any black **** in the inlet pipes I use carb cleaner or brake cleaner Quote Link to comment Share on other sites More sharing options...
station Posted October 12, 2013 Report Share Posted October 12, 2013 check the air filter and the egr valve and clean out any black **** in the inlet pipes I use carb cleaner or brake cleaner I agree with this - Definitely not oil Quote Link to comment Share on other sites More sharing options...
RED BEARD Posted October 12, 2013 Report Share Posted October 12, 2013 i'd go for air filter gobbed up or squashed air pipe (black smoke),not rings or valve stem seals (blue smoke),unburnt diesel/timing out (white smoke).a bit of black when you boot it is normal i'd say,as long as it clears when the load lightens/or you ease off a bit.

karpman Posted October 12, 2013 Report Share Posted October 12, 2013 Drive it like you stole it around the bloke if it clears it's just **** and you shouldn't worry. If it blows up don't blame me lol. This is why modern diesels go into to safe mode and make you drive em at 2000 revs for so many miles. Or when ya put the puter on to do a dpf clean it holds the revs at 3000 rpm for a prolonged time. Karpman Oil burning is blue Quote Link to comment Share on other sites More sharing options...
jayman Posted October 12, 2013 Report Share Posted October 12, 2013 Stick some XADO in change the air filters and give it a boot up the road! Anyone else come across Xado what a product! Quote Link to comment Share on other sites More sharing options...

goodo123 Posted October 13, 2013 Report Share Posted October 13, 2013 It's probably the tarmac flinging off your tyres and the car farting, or it could be that it's had too much Guiness, that makes your poo black.

subsonicnat Posted October 13, 2013 Report Share Posted October 13, 2013 you are burning oil, valve seals or worn out pistons, etc etc. Black smoke is oil.. Quote Link to comment Share on other sites More sharing options...

Traztaz Posted October 14, 2013 Report Share Posted October 14, 2013 Thanks to the guy that supported me on it being oil, 22 years as an army VM working on nothing but diesel wagons should have taught me something. white smoke is coolant , blue is to do with over fueling, or bad air filter, BLACK is oil.

Mainly vauxhall and up until recently ex mod cars. It smokes when he boots it. A quick check of the stick should give him an answer to if it is burning oil or not. And when they start to burn some with the fuel they sure get through it.

TTFN No disrespect bud! But I too spent many moons working on cars! I agree, white is normally water finding it's way into the cylinders. Black smoke was nearly always due to lack of service and maintanance and was blocked air filters. Blue smoke was ALWAYS either shot rings! Degraded or failed valve stem oil seals or oil finding it's way into the cylinders. Quote Link to comment Share on other sites More sharing options...
