One of the main reasons that Kenworth trucks are so popular among owners and operators is because of their incredibly reliable engines. However, there can be issues that you can face when you continue to drive the Kenworth truck for thousands of miles on the road. Over those miles, there may be numerous factors that might make you need to repair your diesel engine. The following are some signs that you could have an issue that needs to be looked at.
Loss of power
Loss of power may be an indication of a camshaft problem, but it may also be an indication of a more severe problem with your engine. Fuel concerns, severe fuel contamination, excessive buildup, injector problems, a failing turbo, or air entering the system may all contribute to this.
Bad fuel economy
Again, you can get low mileage if your camshaft has problems, such as lobe wear. Certain driving habits, such as overloading your truck or accelerating quickly, might reduce fuel efficiency. It can also indicate that your diesel engine needs repair. There might be a leak in your system, tainted fuel, or problems with your filter or injectors.
Excessive oil consumption
Before it results in a significant system breakdown, you should look into the matter if your engine consumes more oil than usual. You can be leaking or burning oil, which might be brought on by unclean oil, an excessive amount of crankcase oil, a high engine vacuum, insufficient piston ring end clearance, worn or damaged piston rings, too high oil pressure, a lugging engine, or an obstructed air intake.
The piston rings get squeezed in the ring groove and can no longer contain combustion gasses on the top side or manage the oil on the bottom side due to carbon packing brought on by broken EGR systems. If oil is burning or leaking, it may lead to other issues and cost more to fix if it is not fixed soon.
Engine banging is a significant engine trouble sign that shouldn't be ignored. Engine knocking may be brought on by problems with the compression, the timing, the fuel injectors, the bearings, the wrist pin bushing, or the wrist pin itself.
Engine compression issues
A lack of compression is one of the most obvious signs of a problem with your engine and a sign that it needs to be fixed. Leaky or broken valves, leaking or broken piston rings, blown head gaskets, camshaft problems, damaged timing belts, or holes in the piston or cylinder may all be indicators of compression problems.
Excessive smoke coming from the engine
Mainly blue or black smoke; excessive exhaust smoke might alert you to a more severe problem with your engine. Numerous issues, including defective injectors, injector pumps, faulty air filters, faulty EGR systems, faulty turbos, carbon buildup, inefficient or incomplete combustion, worn valve guides or seals, or wear in power assembly, might be indicated by this.
Oil consumption may increase due to excessive blow-by, in which more gasses are permitted to escape due to piston and piston ring wear. Root reasons might range from cylinder head problems to problems with the turbocharger to worn valve guides. It may be time to inspect your engine if you're experiencing a lot of blow-by.
It's a good idea to pay close attention to your engine's age and mileage. Suppose your diesel engine is older or has logged a significant number of miles since its maintenance or repair. In that case, keep a closer eye on its health to identify any possible issues before they become serious system breakdowns.
If you are facing one or more of these issues, you need to get the help of a truck repair specialist as soon as possible. Sometimes you can address the issue by repairing your Kenworth truck engine, and in other instances, you may have to go for a complete engine overhaul. No matter what, work with a reputed technician to address your issue.
Why Regular Diagnostics Is Important For Your Volvo Truck
Smaller businesses may be much more affected. To fulfill planned deliveries or do work on a worksite, they are less likely than bigger fleets to have replacement Volvo trucks.
