    Turbo diesel I presume, Lots of smoke could be several things, first is it black, blue, or white smoke? Next, does it run even, on all cylinders, or is it rough? Did it develop suddenly, over time? Does it make unusual noises? Has it overheated? It could be a bad seal in the turbo, I doubt it, a damaged piston, possible, scored cylinders, possible, a pump that is not advancing, maybe, a blown head gasket, possibly. These do tend to eat pistons, best to get expert eyes on it, I know diesels quite well, but without looking at it and testing it,,,, If you could answer all the questions, and tell me if it sounds different while cranking it over, I might be able to narrow it down.

    I need more SPECIFIC information. Does it smoke all the time? Smokes when its hot/cold? How does it idle? What is the condition of the engine oil? Is the oil change overdue? Are there any noticeable oil and/or fuel leaks? What color is the exhaust smoke (black, white, or blueish-gray)?

Thank you for answering some of the questions, the more you answer the closer others can get, see "Solution 1" this is a possiblilty, EGR = Exhaust Gas Recirculation, lets a metered amount of exhaust gas into the intake, it is an inert gas, = won't burn, and helps prevent NOx, by slowing down the burn. If it is stuck open it could be sluggish on the low end, and have more blue smoke, a definate possibility, check it first.

Why the isuzu 2.5turbo diesel intercooler loose power and smokes when it warms up

what ISUZU what body? what year, and what country.
we cant guess all that?????? Injection system types vary by ALL THAT.
that can be lots of things
but the turbo , stops the smoke.. (adds air during times when old non turbo diesels smoked normally)
it could be a bad turbo or a leaking injectors
why not get a mech to service the car.? guessing will not work.

Isuzu trooper duty 1995 loss of power wont rev over 1800rpm

the cars come with many diff. engines. and EFI systems that match it.
so cant help you.
but ill answer in pure physics.
1: lost DC 12v power to the EFI system causing spark and fuel losses.
2: lost engine compression. 1 or more cylinders.
3: lost spark or never doing a full tuneup every 60k at least.
4: bad fueling, too much or too little.
what do do is a few simple tools to discover the truth.

do you want to gue$$, or test.

Sounds like injectors are plugging up. Run a bottle of Diesel fuel system cleaner w/your next tankful. It might take two times but injectors get gummed up easily.

My isuzu 4JA1 engine tends to exhaust white smoke

White smoke means that you have a coolant leak. Two possible causes for that - either the head gasket is punctured and must be replaced or the head itself is damaged and must be welded by an expert. 
Either way the engine must be dismantled to make a full diagnose and repair.

Oil mixing with Diesel and car emits white smoke.

The copper washers on the bottom of the injectors can give this fault if they are not renewed when the injectors are replaced .

If you have changed these allready and made sure you pulled them down exactly as the manual says in 3 stages then you may have a bad injector - see your Isuzu dealer .

Are you getting a lot of black smoke?
If so your egr is more than likely goosed.
Easy fix in a 300.
Mine suffered from this a few years ago and I blanked off the egr. You can make a blank yourself or buy one with instructions for a few quid of eBay.
Well worth it and you will certainly notice the difference.
hope this helps.
