How long do engine bearings last?

When properly maintained, most bearings should last approximately eight to 12 years. Bearing lifespans are represented through a concept called the L10 life. The L10 life is the age to which approximately 90% of bearings of a sufficiently large population under similar conditions will survive.

What happens when engine bearings fail?

When crankshaft bearings fail, the increase in heat, pressure and metal-to-metal contact can cause distortion of the crankshaft and connecting rods, which in turn will cause the engine to seize.
