Diesel injectors have a design life of 100K miles and are a routine maintenance item often overlooked. Symptoms of worn injectors are hard starting, very smokey start-ups overnight, misfiring, loss of power and most common symptom, POOR FUEL MILEAGE. Worn injectors can damage your engine as with age they tend to leak fuel overnight into the cylinders. This will wash the lubricant off the pistons and cylinders creating metal to metal contact and severe engine damage. Running injectors past 100K miles is like playing Russian Roulette with your engine!

Install tips:

Injectors are easy to change by even a weekend mechanic. They are no harder then changing spark plugs on a gas engine.

Only handle injectors with clean hands and leave the protective caps on until the last possible moment, as a spec of dirt in an injector will cause a misfire of knock until the dirt passes or is removed by cleaning the new injector.
