2CYL DIESEL ENGINE SMOKING EXCESSIVLY AND VIBRATING.WHATSTHE CAUSE?

The symptoms you're describing with your 2KD Hilux engine (weak engine with mass smoke, vibrations on rev, and less power) could be caused by several different issues. Here are a few possibilities:

1. Excessive engine oil consumption: If the engine is consuming too much oil, it could be burning the oil and creating a lot of smoke. This could be due to worn engine components such as pistons, rings or valve seals.
2. Clogged air filter: A clogged air filter can restrict the airflow to the engine, causing it to run poorly and produce more smoke.
3. Timing issues: If the timing is off on the engine, it can cause poor performance, vibrations and smoke.
4. Fuel injection system issues: A malfunctioning fuel injection system can cause poor engine performance, vibrations and smoke.
5. Turbocharger problems: A malfunctioning turbocharger can also cause vibrations, smoke and less power.

no year told ,2006 to NOW.
no country told and not sold in USA> Australia I guess.
no engine told,, nobody can guees 6 engines and is an engine question, seems you messed up , but not told why all this started so answers , impossible.

Hi there! I have the same Issue. Did you find the problem by any chance?

generator set will occasionally encounter generator failure in the process of use thatCummins generator setis not generating electricity. What is the cause of it? And what to do about it? In fact, there are a lot of reasons that Cummins generator set is not generating electricity. The following is compiled by Jiangsu Starlight Electricity Equipment Co.,Ltd to summarize the main reasons for generator not to generate electricity and the treatment methods.

check for leaks in the intercooler system
make sure that the variable vane actuator is operational

The question is the source of the vibration. Emissions issues may cause engine misfires and vibration. However, new ball joints suggests you experienced vibration in the steering wheel. Worn ball joints CAN cause this, but since replacement did not fix it, the next source is a worn inner CV joint on a front axle. This CV has to smoothly allow for suspension movement, and the concurrent in-out axle movement in the CV. What happens is the CV binds and generates wheel vibration, which can be severe. Have the garage check for wear in the inner CV carriers. Replace the axle if necessary.

regarding vibration, this can be caused by a lot of things. some of which are broken engine supports and very low idle (below 700 rpm can cause a lot of shakes).

if your vehicle runs on diesel, have your fuel injectors cleaned and air filters replaced. then check if the smoke is still existing.

what color is your smoke?
1. white / light bluish in color - caused by water/coolant entering the combustion chamber.
2. black/gray/dark bluish color = caused by oil entering the combustion chmaber.

possible solutions for these are:
1. replace head gasket
2. replace valves/valve guides/valve seals
3. have a shop check your cylinder head for cracks or leaks.

Not on a Gas engine, but diesel engine yes.

Diesel engine white smoke means leaking head, intake, or your turbo is not working.

Gas engine leaking intake would only cause rough idle, no power, etc,,,,

I'm sorry to say this, but it sounds as if your turbo is shot.

BLUE SMOKE from exhaust - Causes: Engine is burning engine oil, injection timing is incorrectly set.
