my vl has been blowing black smoke and i wanted to know if this is usual for a turbo or it means there has been damage done to the engine. it seems to happen whenever i rev the car or put my foot down to over take a FORD or any other ****ty car . can someone help.

Sounds like it's running a little rich.Have you done some mods to it latey or has it always done it.

Nothing to worry about if it's black smoke...means running rich thats all. Sensor problem or AFM. Only worry if it's blue or white smoke Some original photos have not been recovered yet.

i have had all sensors replaced recently and its running 12psi, i was also told that if the air filter was old this may make it blow black smoke. but i was also told that if it blows black smoke the turbo may be f!@%ed is this tru.

hey all,black is fuel as said b4,blue is oil(rings) and white smoke can be a number of things getting burnt eg, brake fluid,power steering fluid,water and if your turbo is fuct there will be a constant bit of bluey/white smoke out of your zorst and then a big puff when u take off. black is just fuel nothing else

My car used to blow a ****load of black smoke on startup... turned out to be 3 injectors leaking... get your injectors/fuel system pressure checked

Try changing the plugs. I had the same prob, i changed the plugs and it fixed it.

i had the same prob with my atmo have you read the computer codes as they will tell you were the prob could be its not exact but it could be a start if you need to know what the codes me let me know as i have them all here Some original photos have not been recovered yet.

My car blow blackish smoke when it pings, my fuel pump is dying and it leans out under high boost, pisses me off cause I cant put my foot down enuf.

Mine also blows black smoke when i give it a poke, it's just running rich Some original photos have not been recovered yet.

Mine was doing the exact same thing. Took it to Turbo Tune and it turned out to be a hole in my intercooler (not actually a tear or puncture but a bung had come loose). They fixed that, gave it a tune and it's running better than ever before.

MY VLT is doing funny things I start it in the morning turns over after first 2secs no black smoke ,but drive it for a while and then leave it start it again it takes longer to crank and it idles a bit rough for like 30secs and it is blowing black smoke but then comes good? I have checked the AFM ,Coolant Temp Sensor the Computer Codes on ECU checked and reset ,all that comes up is the Knock sensor code as I have no wiring from ECU to knock sensor yet. Motor has just been rebuilt and Injectors all cleaned etc... New plugs and leads ,oil /oil filter air filter ,Only thing I havent checked if Fuel Filter but was replace 10,000k's ago and the motor has only dont 1,000k since rebuild so far any Ideas or anything I have missed out on? I didnt have new Fuel Pressure Reg as I bought 2nd hand one off the forum a year ago but it has been tested and holds pressure ok.. Any Feedback welcome guys.

change the dizzy cap and rotor, i'll be that's what it is. i had a similar problem in my car recently, blew black smoke sometimes and ran very rich, turned out the dizzy was rooted. put another one on and fuel consumption and everything returned to normal.

Yup will do that actually ,Thanx StockyMcstock Some original photos have not been recovered yet.

i found my calais did this alot, on start up aswell. more than likely the spark plugs. changed mine and had no probs. beta check ya leads while ur at it aswell just to be safe

The Spark plug have only 1000k's on them but i will take em out anywayz ,I amy have to recheck the Gap's on them I am sure they are at 1.1mm but will check it out..

Will not having the Knock sensor wiring installed yet cause the Black smoke on startup? As I dont have the wiring yet but the knock sensor is in the block. All ECU Codes have been checked and the ECU reset and it only comes up with the knock sensor code ,due to the wiring not installed yet.. Any help greatly appreciated VL Brainiacs..

no to your question and as far as the knock sensor is concerned , dont even bother with it. just keep ur timing , fuel and boost on the sensible side of things and u wont need to worry about chances of pinging , therefore no knock sensor needed.

Oh ok cool will have too look at other things then Mine only blows black smoke for about 20sec everytime i start the car thats all

The ECU runs rich from cold start, there may not even be a problem with blowing some black smoke at startup?
