          Carrying on a tradition of durability and dependability, Clevite Bi-Metal (aluminum) engine bearings feature 100% lead-free aluminum silicon. Engineered with 60% more silicon than comparable competitive replacements, they provide better conditioning of journal surfaces. This results in greater seizure and wear resistance.

          When do engine pistons rings go bad?
          Engine piston rings can go bad due to wear and tear, inadequate lubrication, overheating, manufacturing defects, or improper installation. Symptoms of failing piston rings include reduced engine power, increased oil consumption, and blue smoke from the exhaust. Regular maintenance and inspection can help identify potential issues.
