When did the Cummins ISX diesel engine come out?
Since its launch, the ISX has been the core of Cummins’ diesel engine fleet. Not only has it advanced with quicker processing, but it has also increased fuel efficiency since its debut. In 2002, the ISX became one of the first diesel engines to incorporate an exhaust gas recirculation (EGR) cooler system.
Are there any problems with the ISX engine?
Like any other engine with an EGR, the system can cause some problems. On the ISX, it most likely has to do with a leak in the EGR valve. This is a difficult problem to diagnose, but monitoring the coolant consumption can help. If you notice that it’s using a larger amount of coolant than normal, it’s probably worth investigating further.
Are there any problems with the Cummins Engine?
Throughout its production history, Cummins has made various changes to the engine in order to keep up with the increasing restrictions, changing from a dual-cam to a single-cam and adding a cooled EGR system to reduce NOx emissions. Despite its popularity, it does have its problems, like any other engine.
Why does the engine surging stop at idle?
If I put a load on the engine by turning on the airconditioning compressor, the surging will often stop.

My car has a manual transmission.
What happens to the engine rpm when idle?
At idle, on an intermittent basis, the rpm repeatedly sur… While idling, my rpm will surge from about 1100 to 1700 over the time frame of a second or two then return to 1100 over that same time frame, then repeat. If I put a load on the engine by turning on the airconditioning compressor, the surging will often stop.
Why is my engine surging at high RPM?
Your ignition timing may be set incorrectly. Check and adjust, ignition timing. Ignition system problem causing a, weak spark. So, if your engine has a distributor; check and replace distributor cap, rotor, ignition wires and spark plugs. And, you should also have the coil packs checked.
How can I tell if my Cummins engine is having a problem?
The best ways to identify if this is the problem is first to make sure the tank has enough fuel. Next, check whether or not the pump is actually delivering fuel to the engine. If those are both correct, check if the pressure is low. Low cranking speed: The engine needs to turn over quickly for the fuel pump to generate pressure.
Why is there white smoke coming from my Cummins Engine?
Water or oil in the fuel: Clean fuel will burn properly, but if there is anything added in, it can prevent the fuel from burning as it should. If water or oil is in the mix, it may be the cause of white smoke coming from the engine. Water can cause major disruption, so it needs to be taken care of promptly.
Why does my Cummins diesel engine not start?
If you run into issues where the engine struggles with starting or accelerating, it’s likely experiencing a lack of power. With these types of Cummins diesel problems, you can most often link it to a fuel-related component. Be sure to check for:
What kind of SCR does Cummins ISX cummings use?
The ventilated exhaust lowers the combustion chamber temperature. The ISX Cummings started featuring the selective catalytic reduction (SCR) system in 2006. It injects urea, which is an active element in diesel exhaust fluid (DEF), into the exhaust.
When did Cummins start having problems with EGR?
For example, engines engineered before 2002 will experience more problems with EGR compared to modern types. In 2008, Cummins began noticing the SCR system experienced failing revolving parts, interfering with the engine’s horsepower. Clogged inlets came about in 2010 when recirculation was occurring, also affecting HP.

Why does my ISX truck won’t start?
I took the truck to my regular mechanic to have a full service done, and after they replaced all the fuel filters, it woudln’t start over their pit. (the primer pump was whirring away everytime i turned the key to the on position) Long story short, they diagnosed it as a bad high pressure pump.
Why was the Cummins ISX RV engine discontinued?
Cummins briefly produced a version of the ISX especially for RV applications which made 650 hp at 1950 lb-ft of torque. The engine was discontinued because it was proven to be unreliable. There was also no extended warranty coverage for the RV engines. Cummins had several workarounds for various issues but eventually decided it was not profitable.
What’s the problem with starting a car slow?
Same problem right off the bat, slow cranking, but it did start at least. Let it run for a little bit and checked battery voltage with the car running and it was 13.8 volts, then 12.4 with the engine off. Restarted a number of times and it just cranks very slowly, but did start 5 or 6 times while I was poking around.
Is the Cummin ISX a good or bad engine?
Front engine plate warps causing oil leak. Isx isn’t one of the better engines. Might be improved on newer years. But the older years. if you get one. They like mobile delvac or delo 400 the best. 2010 or newer not sure on.
How does a 2006 Cummins ISM work while driving?
hello I have a 2006 Cummins ISM (ESN, 35127420 ) This unit while driving surges with a small puff of black smoke, while watching the EGR data in insite, while at crusing speed arouns 1/2 to 3/4 throttle the EGR delta pressure bounces from about .5 to 4.5 inhg and the EGR cooler efficiency changed to NA.
Is there a problem with my Cummins turbo?
As it starts to pull then power seems to be halted but the turbo continues to spool. It will do this continuously thru the entire gear up down up down. If i shift while acting normal it shifts normal. If i do it while its acting up it will sort of sneeze access boost. When ever it surges it puffs black smoke Just had everything run thru insight.
