Are there any problems with the ISX engine?

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.

Why does my Cummins ISX engine flatten out?

The ISX also has a history of camshaft issues. We discussed this briefly in Cummins ISX Engine Spotlight. In short, an ISX camshaft can flatten out. This is not because of an issue with the camshaft itself, but with the rocker arms. According to Cummins, there was a production of rocker arms that prevented proper oil flow, starving the components.

How many times has my ISX 650 been rebuilt?

A number of our members have the 650 in earlier model coaches, usually Heritages, and have had problems. My ISX 650 has been rebuilt 3 times in 58,000 miles. Last time was pre emptive as Cummins couldn’t tell me if they used the upgraded parts in 2015. After disassembly the Cummins shop said it was only a matter of time before it broke a valve off.

Can a worn camshaft cause an ISX to fail?

Apart from performance issues caused by a worn camshaft cluing you in to a camshaft problem, there aren’t any particular symptoms to watch for that indicate whether or not you have these rockers. This issue is usually found after a camshaft repair or overhaul, when the timing might be affected.

Why is my Cummins ISX intermittent shut down issue?

That is a common problem with them leaking. They will only leak when they are running. After they shut off and the engine is running the main fuel pump will suck fuel past this pump. If the electric pumps leaks out fuel when it is on, then it will allow air to get sucked in once it shuts off. Thanks for all of the advice.

When was the first Cummins ISX engine made?

The ISX engine by Cummins is one of the most popular diesel engines on the road today. The first ISX was produced in 1998, as a response to the EPA’s tighter emissions restrictions. It soon replaced the N14, the other workhorse engine produced by Cummins.

How long does it take to overhaul a Cummins ISX?

I just had a 2010 ISX overhauled by a certified Cummins shop. They started engine when done and within 10 minutes of running a rod came through the block.

How big are the rod tabs on an ISX engine?

In the ISX “saw cut” connecting rods, the tabs on the bearing shells are only offset approx. 2.89mm (.114”). Although it is noticeable if the shells are installed incorrectly, the connecting rod can actually be installed this way. There is enough clearance that the rod can be bolted in place to the crankshaft.

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.

What causes hesitation and surge on the ISX Cummins?

Which is the most common ISX failure in a Cummins?

The turbocharger is one of the most notorious ISX failures and is expensive to fix. While they are ideal for direct throttle response, VGTs often experience a buildup of carbon, soot, rust and other contaminants.

Why does my Cummins ISX have a sliding collar?

Click to expand… If the one on the ISX is built like the HE351VE used on the 6.7L Cummins in the Ram trucks, it is a sliding collar that changes the geometry of the turbine housing. The soot can build up in the moving parts and the actuator can’t move it properly.

How much is rebuilt ( overhaul ) 2006 Cummins ISX?

A basic rebuild is just six new pistons and liners. You can go as far as replacing the rad and air to air too if you want. So it is a matter of how much of the engine/truck you want to replace. I am sorry to say that in your case you may be looking at a complete drop in engine from the story you told.

What kind of engine does a Cummins ISX have?

This is quite a revolutionary concept for the Cummins ISX having both the internal and external combustion in one engine.

How does Rankine cycle work on Cummins ISX 15?

The Organic Rankine Cycle technology in the Cummins ISX 15 aims to recovery as much energy as possible through heat recovery. Across the board, only roughly 33 percent of energy is used towards moving the motor.

How often does the fuel injector activate in an ISX engine?

Then, it’s distributed through the tubing to the rail system for storage under extreme pressures— about 35,000 PSI or higher. This version of the ISX relies on an engine control module (ECM) to monitor the timing and pressure. The ECM can activate each fuel injector up to five times per combustion cycle.

What should the oil temp be in a Cummins ISX?

Cooler temps comes up to 210 and fan goes on. Then coolant temperature drops back to 190 or so. That’s when going up hill. But oil continue to rise up to 270+, ( at least that’s what gage tells me) until msg appears ENGINE OIL IS TOO HOT! And then engine shuts Off.

Why are the Rockers on my Cummins ISX not working?

These bad rocker arms stick and smack the camshaft, causing the lobes to flatten. You can fix this failure by replacing both the affected camshaft and the rockers. If you don’t correctly diagnose the problem and leave the faulty rockers, then the same thing will happen to your new camshaft.

Why does my Cummins EGR have white residue?

Similarly, there might be a white residue left behind from the burnt coolant. This is another telltale sign of a leak. This kind of problem is more common on older style EGR systems, as many newer ones have tried to address and fix the issue. The ISX also has a history of camshaft issues.

Is the ISX Cummins 871 a good engine?

The CM-870 is the version prior to the 871 and is also a very good motor when properly tuned. Now, the problem children are the CM-2250, CM-2350, and the X-15, which there is not yet that much feedback on. The 2250-2350 are high compression motors, it does not like to be turned up, but can be tuned. Then we have the fuel system.

How much horsepower does a Cummins ISX 15 have?

The newest Cummins ISX 15 operational efficiency actually delivers more horsepower than in older ISX engine models. Engine builders at Capital Reman Exchange performing line boring on an engine block. The ratings on the ISX 15 range from 400-600 hp (298-447 kW) with 2050 lb.-ft. of peak torque.
