The single most important factor to be considered in selecting the proper compression (top) ring face coating material is the service requirements the engine will be operated under. Will the engine be subjected to unusual speed or load (high temp conditions), stop and go short trip driving...
The most common items over looked during assembly and installation of a rebuilt motor, are the motor mounts, transmission mounts, and the harmonic damper (balancer). Motor mounts are commonly bonded together using a variety of rubber compounds, while most OEM dampers utilize an elastomer...
Every engine requires a certain amount of oil flow to keep the bearings, camshaft, valvetrain and other moving parts lubricated. Oil forms a barrier that prevents metal-to-metal contact and reduces friction and wear. In the bearings, it forms a wedge that actually lifts and supports the...
