Stiction is on the cover of turbo diesel magazines and in the conversations between diesel mechanics and drivers.
AMSOIL has a trick to let you feel stiction right in your own kitchen.
The Not-As-Quick-Once-Picked-Up Challenge
Pour some water on your countertop. Now take a paper towel and place it over the spill. Can you feel it? There is a noticeable difference in the amount of drag after the towel absorbs the water and that drag is stiction.
Under the Hood
Let's look at your diesel injector. A tiny amount of engine oil has the high-pressure job of driving the intensifier piston under extreme heat conditions. With wear and tear, that oil begins to break down and will leave a residue, gummy-like substance on the internal parts of your engine. Now when you turn on your engine, it will experience a drag. The residue that has built up causes an internal dragging friction better known as stiction.
Doc? Is She Gonna Make It?
Stiction can occur on your diesel injectors and the symptoms are easy to spot. A failed injector, slow starts, bucking or chugging, and loss of power or your diesel's hesitation to accelerate are all indicators of stiction, but stiction can be minimized. ;
