I just resealed the oil pan and changed the water pump. I filled all of the fluids. When I restarted the car the valves are rapping really loud. It sounds like a diesel. I am thinking the oil is not circulating through the engine. I do not recall disconnecting anything electrical that would limit the pump from circulating the oil. Any ideas of what it could be? Appreciate your help.

  1. Check your oil level and then remove the oil filter to see oil is inside it.

    1. NO OIL in engine
    2. Bad oil filter, clogged
    3. Accidentally left shop rag inside oil pan and the pick up tube is clogged.
    4. Left oil pump pick up on bench when reinstalled pan
