Hi,

I have a 91 80series and overhauled the engine recently with cylinder and piston rings work, also serviced the injectors, pump and turbo over a period of time. My rig is throwing a lot of black smoke on acceleration and starts making gargling noise from the snorkel. Some of the other observations are idling being jumpy sometimes and lack of power. Can somebody please tell me what is going on and how do I address this?
 
Your location says India, so its a diesel, correct? Not sure what type of diesel you guys have, but here in the US Ours is terrible thanks to the epa. Black smoke is fuel, normally. I want to say you have a timing problem, but I have ran into a lot of injectors that have stuck open which in turn lets air into the fuel system and causes the same.
 
you may want to post this in the diesel section you will likely get responses from people more familiar with this engine.
 
Agreed to get this on the diesel section for better response. It does sound as if your timing is out, remember on this engine you need to have the camshaft timing and the injection pump timing spot on. The black smoke would indicate incomplete burning of the fuel.

The odd thing here is you say idle is 'jumpy sometimes', this could be air going through the filter/pump lines. Put a length of clear pipe between the filter and the pump, and another piece between the bleed off rail back to the pump/tank junction.

Run the engine and after awhile there should be no air bubbles anywhere. A common problem is you have all the work done, and then use the manual primer to pull up fuel and prime the system. The diaphragm perishes and becomes porous, this allows air into the system, you then assume it is something wrong with your build, check the easy stuff first.

If no luck, then go to a diesel workshop who has the special tools needed to time the pump correctly.

regards

Dave
