Pre-Installation Inspection Tips

  • Inspect the entire engine thoroughly - If there is an issue, you want to find out before you have it installed in the vehicle.
  • Match the long-block with your old one.  Make sure they are exactly the same.
  • After you have the old engine out, set it next to the used engine and identify which components need to switched over.
  • If you find damaged components in your inspection (timing cover, oil pan, etc.), simply swap the components with your old engine.  Generally, bolt-on accessories can be swapped with no issue. 
  • Don’t install a replacement salvage engine with damaged parts.  This may cause the used engine to fail prematurely.
  • Inspect timing components on engine, if miles are over factory specification for a timing belt or chain, replace timing components.  Best practice is to always replace the timing belt. It's generally inexpensive to do when the engine is already out of the vehicle.
  • Inspect all gaskets for bolt on accessories and replace any gaskets that look brittle or are leaking.
  • Change over any bolt on accessories needed off your old engine.

  • Clean or replace oil strainer and pick up tube screen. 
  • Replace oil pan gasket & rear main seal.
