What causes a diesel engine to stop running?
The camshaft wears and the valves do not open or seat properly. The piston rings and cylinder walls wear resulting in lost combustion. The turbo starts to drag. The exhaust becomes plugged up. The lift pump does not deliver enough fuel pressure. The injection pump and delivery valves lose their mojo.
Why does my diesel engine make a hiccup noise?
You will notice a “hiccup” noise when the engine is idling. To keep your diesel engine functioning optimally and lasting a long time, perform the following checks to identify the cause of this problem. You can generally understand what is wrong with a diesel engine by the color of the smoke being emitted from the exhaust.
What to do if your diesel engine is rough running?
A valve adjustment (on engines up to 1885) followed by a compression test must be done first. If the compression is weak or highly imbalanced you will not be able to solve the rough running problem short of an engine overhaul. If compression is good the very next thing that Kent recommends is to do a DIESEL PURGE.
How can I tell if my diesel engine is low on fuel?
The best way to diagnose this is to look at the fuel supply in 3 areas. 1. Low pressure supply from the tank to the high pressure pump (HPP) – some vehicles rely on the HPP to suck the fuel from the tank whilst others have an electric pump in the tank or fuel line to supply fuel to the to the HPP.
What causes a diesel engine to run bad?
Common Smoke & Power Problems: Engine runs bad – gummed injection system 5. Common Smoke & Power Problems: Engine runs bad – excess carbon buildup 6. Common Smoke & Power Problems: Engine runs bad – low fuel flow to injections 7. Common Smoke & Power Problems: Engine runs bad – poor compression 8.

Can a rough running diesel engine go forever?
Rough running old diesels are very common. Yes, we all heard that the engines can go forever – BUT are they healthy and happy during the journey? Kent can tell you from personal experience if they are not “happy” they will not go forever!
Why do I have white smoke coming from my diesel engine?
Problems in this area will cause diesel engine starting problems, uneven running and white smoke when the engine is cold. This speaks for itself- not enough fuel in the tank or a problem with supply pipes being cracked, bent, collapsed, restricted or some kind of restriction in the tank.
