Understanding and resolving your common rail diesel problems (2024)

Common rail diesels have been with us for 10 years now, and there’s no sign of their problems abating! Almost allcommon rail diesel problems are expensive. This makes preventative maintenance a very valuable investment indeed for your vehicle. Since so many of our customers own common rail diesels, Jimmy and I thought we should help you to identify and understand the sorts of problems regularly encountered. That then makes it a lot easier for you to decide what action you need to take to solve your particular problem—at low cost—before it becomes more serious!

Firstly, here’s a list of most of the usual common rail diesel problems:

• Smoke
• Power loss
• Rough idle
• Engine rattle
• Dirty diesel engine oil
• Oil use
• EGR valve problems
• Inlet system deposits
• Turbocharger failures
• Excessive diesel particulate filter regenerations

CRD Fuel Enhancer will restore injectors and avoid common rail problems. Satisfaction Guaranteed

Simply add CRD Fuel Enhancer to your diesel and common rail injector problems are solved.

Next, you need to understand whatcauses these common rail diesel problems, andwhy:

• Diesel fuel quality… Avoid the cheap stuff. Avoid using truck diesel in light common rail engines.
• Operating conditions… If you do a lot of short runs, excessive idling, cool operating, light engine loadings, this will contribute to deposit problems in your combustion chamber, exhaust spaces, turbocharger, and diesel particulate filter.
• Common rail injection systems arevery high pressure and high temperature… sufficient to degrade the fuel, leaving deposits in your pumps and injectors, and lowering your fuel’s lubricating ability. Your fuel filter going black is a sign of this happening.
• Sticking fuel injectors… Your fuel injectors then stick and allow excess fuel which also results inengine rattles, carboning up of your EGR valves, turbochargers, DP filters, combustion chambers and more.
• Piston ring deposits also form, which allows compression blow by pressure into your sump, and heavy soot contamination of your oil.This pressure is released via your crankcase ventilation system into your air intake system. This carriesan oil mist which mixes with exhaust soot from your EGR valve,fouling your throttle body and choking up your intake manifold.

Here’s howto rectify these common rail diesel problemsbeforetoo much damage is caused:

• Use CRD Fuel Enhancer with every fuel tank. It’s cheap to use (you’ll use only 10mL per 80L diesel). Faulty CRD injectors can normally be fully recovered, by just using the CRD Fuel Enhancer. The cleaning and lubricity power ensures that your injectors meter fuel accurately, without over-fuelling. It is evencheaper to use than 2 stroke oil and has far stronger lubricity and detergency.
• We recommend usingFlushing Oil Concentrateto clean your oil system of soot and sludge, and free up piston rings to tighten the seal against blow-by and oil use. Doingthis every oil change is low cost and will keepyour engine cleaner and healthier than ever.
• Using CRD Fuel Enhancerand Flushing Oil Concentratein combination willdirectly address your inlet system deposits, injector fouling, smoke, injector rattles and power issues.
• If you already have heavy inlet deposits,and there may be 2-3 cups of gunk to deal with,we recommendthat you physically clean them, rather than spray solvent through your intake and risk serious engine damage.
• If your engine already has heavy co*king of combustion chambers, turbos, EGR’s or Diesel Particulate Filters, we recommend you also use FTC Decarbonizer in your fuel. This will actively burn off carbon from combustion and exhaust spaces, turbochargersandDP filters. This is especially advantageous when a lot of short runs, idling or light duty use isencountered.

Use ofthese three products as directed will successfully eliminate over 80% of all common rail diesel problems. Got a problem not listed above, or need more detailed advice on how to best resolve your common rail problems? Jimmy and I are here to help, so give us a call on 07 33766188.
