   Today finished up with changeout of the oil filter and checking the CAD.   
     The CAD appeared fine, not cloudy, and the circuit board easily seen.   
   Primed the system before starting.  Oil seemed clean and running.  Start   
   up and within a minute, a smaller boom and then a slightly larger one.   
   I immediately shut it down once again.   
      
   Next steps?
