Excessive fuel smoke coming from my exhaust

I just bought an 89 ford with a 7.3L diesel. i noticed that there is an excessive amount of fuel smoke coming from the exhaust. and it seems to be using a lot of fuel. and it seems like it is straining pulling a small trailer.

    well i think i will try the fuel filter someone else mentioned that to me i am not really familiar with diesels.

    This really sounds like a timing issue (too late), but I'm not that familiar with your particular engine to say for sure. Did the previous owner put in fuel pump modifications or injectors for more 'power'?

    Is the turbo spinning?

Change fuel filter. I know it doesn't make sense. It seems like you're getting too much fuel, so the filter shouldn't be plugged. But that's how they act.

Have LT 1536 . Smoke started coming out the exhaust but engine sounds healthy


Depends on the colour of the smoke.
Unlikely an engine will sound healthy emitting black smoke - excess fuel.

An engine could sound healthy emitting white smoke (steam from coolant) but not from white smoke (excess unburned diesel).

Most engines emitting blue or blue-grey smoke from burning engine oil can sound very healthy.

Isuzu 3000/Diesel/Turbo/Wizard, I can see a bit of Oil coming from Intake/ThroughBody direct to the Turbo & there also a White Smoke from the exhaust + Misfiring and the car is not pooling as uses to be......


Turbo shaft oil seal is probably leaking a little bit, though not ideal it isn't unusual and not particularly detrimental (mostly).

The white smoke indicates either a water or coolant ingress into the combustion chamber or an excess fuel condition. A small fuel excess usually results in a increasingly dark smoke, grey to sooty black and sometimes an increased diesel knock but large amounts of excess fuel results in white smoke which is unburned fuel.
This is often the result when the fuel injectors are sticking, dribbling, leaking and misfiring could also be a further symptom. Bad starting could be caused by several things needing attention but poor injector performance can be a major factor.

I suggest you have the injectors removed and tested.

My mazda 626 has a strong potent smell coming from the exhaust


You don't mention what that smell is reminiscent of?

You don't mention the colour of the "smoke" and you didn't say whether the engine is petrol or diesel?

You don't mention whether the road behaviour/performance is normal?

White smoke is almost always steam or in the case of a diesel it could be an unburned fuel mist, grey/black is excess fuel and blue or grey/blue is burning oil.

Some steam is fairly normal until the engine and exhaust system is hot but excessive amounts could be one symptom of head gasket trouble. If the engine is drinking coolant and sending it through the exhaust as steam it will sometimes smell spicy.

Burning oil smells a bit like burned eggs in the frying pan.

If the car hasn't ultra-low sulphur oil and fuel the catalytic converter will convert sulphur traces into hydrogen sulphide - the bad egg gas...

Audi q7 black smoke coming out of exhaust


The reason my audi q7 had heavy smoke was because the diesel fuel injectors were dripping which can be checked by means of a leak test, this was caused by the fuel injection pump depositing micro shreads of metal in to the injectors, 5 of which failed.
If you're problem is the same, you will find that the problem occurs when the engine is hot, when the engine has been ticking over for a short period and then you hit the accelerator the heavy smoke is the excess fuel burning off, equally if the idle period is longer you will notice smoke in you're rear view mirror. Audi are well aware of the common engine faults, proof being in the 3 years or 60000 mile warranty, the only top motor brand that don't offer 3 years unlimited ( Bmw, Merc, lexus, hell kia & hyundi have more confidence), you may think I have been unlucky and landed a bad one, I bought a second one as i thought the same which low and behold i had full injector replacement and £1800 turbo fault. each car developed the faults between 63000 & 77000 miles, if you buy a second hand diesel audi with a 3.0 engine or above you are buying the name not reliability which is proof when you look up audi's on autotrader, there isn't many with more than 150000 miles, the same can't be said about BMW & MERC which have there cars with 250000 plus.

I have bmw 525 diesel. I see excess white smoke


white smoke from a diesel is usually lack of fuel, black smoke is to much fuel, check your fuel filters for restriction. this is providing that the smoke is not coolant in the exhaust but if that's the case it should be overheating. also if it is cold were you are you might have a fuel gelling problem that will also cause white smoke. just put some anti-gel in the fuel and see if the problem goes away.

1992 gmc sierra turbo diesel starts and idles fine until warm up


It's time for a Italian tune up!

The blue smoke can be one of two thing.

oil drop from the valve stem (from engine head to cyclinders)
or
diesel soot collect inside the exhaust system.

===
I will take a 5-10 minutes high rpm (not redline) ran on the highway.
Pay close attention to the rear view mirror and look for black diesel soot.
=== I will use Diesel Cleen or similar product to condition the fuel. (keep moisture down)
Use the recommended amount of SEAFOAM oil additive to condition the valve stem seal/rubber parts.

I can not rule out excessive blown by.
Can you get a diesel compression tester?
When was the last valve adjustment?

Please post the actual odometer on the engine and I will follow up on it.
