Why Do You Need a Crank Seal Guard? A crank seal is one of the most important parts of your engine. To seal the crankshaft end, materials like rubber and metal are typically used. The crank seal keeps oil inside while preventing the entry of dirt and other particles. If the seal malfunctions, there will be a leak, which could seriously harm the engine. Similar damage can be caused if the serpentine belt breaks, which keeps the functions of the vehicle going. N55 Crank Seal Guard can protect your engine! What Causes Crank Seal Failure? Your engine's crank seal may break for several reasons. The likelihood of experiencing crank seal failure increases with vehicle mileage. 1.
