My 1992 nissan terrano blows to much black smoke .how to fix this .some say i have unbirt fuel?


if diesel and turbo , check turbo operation of for holes in the intercooler
if turbo or naturally aspirated check/ replace injector tips as black smoke indicators squirting and not atomizing
if petrol check for excessive fuel pressure, faulty injectors , leaking injector seal
regardless of petrol or diesel --black smoke indicates incorrect air / fuel ratio ( too much fuel) so injectors, intercooler, bad turbo or blocked air cleaner are all candidates for the fault

I drive a vw polo tdi 2006,when I went up the brigde it made a strange noise then black smoke started coming from the exhaust could not see even the car behind me,what coused it?


TDI I take is turbo direct injection so if that is the case you have a turbo problem or a split intercooler
what ever , the air/ fuel ratio has altered to excessive fuel
the noise could be a blown intercooler hose , split intercooler or turbine wheel in the turbo breaking off
Take it in for a proper diagnosis and have the codes read

Black smoke and intercooler hose swelling when reved up


black smoke is not enough air for the mixture
the intercooler hose swelling up when the turbo cuts in indicates a blockage in the intercooler or air inlet into the manifold
with a blockage ou will get black smoke so check the intercooler cores for blockages

1992 Peterbilt 379 feels sluggish pulling load up hill and is blowing black smoke


have a turbo boost pressure test done under load on a chassis dyno
under load the boost should be right up
check for leaks in the intercooler hose fittings or cracks in the intercooler
black smoke under load indicates a faulty turbo or turbo air leaks.

Blows black smoke when running 2600 rpm and boost goes down


I assume its the 6.0L diesel...If so sigh......double sigh.. I had one of these...triple sigh. I need a bit more clarification. How many km on the engine/vehicle. Also, you say that it blows black smoke while running at a constant speed at 2600 rpm, or while you are accelerating to 2600 rpm. Also, when you say the boost goes down, does it decrease by itself, or when the throttle is let off. The boost naturally goes down when the throttle is released (not trying to be a ****, i dont know how much you know). However, if the boost is going down by itself, while the engine is under load (its not supposed to, it should stay constant) it could be a couple of things, which "can" contribute to black smoke. If there is a leak anywhere from the turbo to the intake of the engine, it will cause the engine to get less boost, which means less air into the cylinders, which means black smoke. Check all of the connectors/tubing coming from the turbo to the intercooler, and from the intercooler to the intake manifold and see if there are any problems. The more costly problems which results in boost going down, and black smoke, deals with a problem with the wastegate on the turbo (controls how much boost is produced, and when too much is being made, it will bleed off excess pressure). So if your wastegate is malfunctioning, your boost will go down and you will get black smoke cause the engine is not getting enough air. also, around 160km...80mi, the injectors "can" start to go on the 6.0L diesels....I would check the turbo for leaks, the tubing for leaks, and the intercooler for leaks (a big rock can punch a hole in radiators and intercoolers...intercooler will be in front of the radiator). I hope this helps

Welcome to the world of diesels....

Black smoke is produced when too much fuel is injected into the cyl. There could be several issues here, but I would start with running a diagnostic on your O2 sensors and MAS/MAP sensors.

I hope this helps
