Try to face the pump and motor marks, half a centimeter are many degrees of crankshaft even if you do not believe it. Those brands, not the factory brands may not be correct.
The white smoke is because the diesel is sprayed but does not burns inside the cylinders coming out in the form of tiny droplets that are the ones that form that smoke, it also has a characteristic smell and in large concentrations it makes the eyes cry.
This can be for several reasons, for example. Lack of engine compression, or that a heater (incandescence spark plug) is defective or that the pump injection point is delayed.
To know if the last problem is the latter, it is enough to heat the engine to its service temperature, and accelerate thoroughly keeping for three seconds to the injection cut, if failures are observed in the rounding of the engine, white smoke or slight firecrow in the exhaust, it means that the pump is delayed, it must be turned on its anchor in the opposite direction to the engine turn.
The first cylinder in that engine is the one that is closest to the distribution, I mean that of Alante at all. And the room is the one that hits the gearbox.
If you had any fucked injector, you would easily notice it because I slowed the engine like a gallop horse, that is, in three cylinders.
If you make these symptoms, the most common is to disassemble the injectors shortly after having stopped the hot engine, if any of them is wet of diesel and presents as carbon balls it means that it is defective and does not spray well.
The appearance of an injector that works more or less well, must be dry and covered with a finite soot like chalk but black dust.
To start the tachy adjustment, the easiest thing is to look at the distribution marks, because when crankshaft and camshaft coincides in their respective brands, cylinder No. 1 is in compression.
Another way to know is to put the contact, turn the engine by hand with the tubes of the loose injectors and when diesel comes out through the tube it is giving you the exact point where the end of the compression occurs.
Greetings and if you need help you only ask for it.
