    you want to remove the valve covers, looking for loose wires, test the solenoids with an OHM meter. Run the motor and push down on the center pin cover the assembly with a rag then look for leaking, loose solenoids, or cracked housings. If it happens when it is hot check it when it is HOT.
    Just a thought!
