Remanufactured High Durability Engines are built with all new valvetrain parts, hardened valve seats, a double roller timing chain (where applicable) from selected cores using only first repair sizing.


  • After being assembled, we pressurize the water jacket with 30 lbs. of air pressure. As a result of these tests, you can be sure your unit will not have coolant leaks.
  • "SIM” test – after pressure testing, our final check of engine performance is a spin test. We turn the engine at 400 RPM with oil pressure lines attached. The test measures compression on each cylinder, oil pressure, oil flow and allows an easy visual check that oil is reaching all critical areas. This test also allows the rear main seal to be checked for leaks.
  • High Durability Build, Timing Cover, Oil Pan, Valve Covers & Balancer Installed
