Nissan Bluebird engine will not start

   Production plants: Nissan Motor Company
   License plate number: Bluebird L-VRU11
   Engine Model: CA16-type
   Production year: 1985
   Mileage: 84000km
   Failure Symptom: Engine will not start.
    Maintenance process: just a charged battery, starter motor turn was also very good, but the engine that is not the beginning of the explosion, but also heard a 'click, the click "sound.
   Set timing light, timing light flashes to indicate Digiprog 3 that the spark plugs sparking. Float chamber to inject a small amount of gasoline. Long-term placement, gasoline vaporization of volatile components evaporate Pat, which could adversely start, so ED carburetor upper adding a small amount of gasoline. Re-start or start-up. Remove the spark plug survey, the spark plug is not so wet.
    Measure the compression pressure, the results of the stress is only 200-500kPa, this situation is no difference with the old car scrapped. Remove the cylinder head and then release the engine oil, peel the intake and exhaust valves on carbon. car diagnostic tool Because of carbon's sake, can not embed the valve seat and valve resulting in poor compression, but also issued a 'click, click into "sound.
    To confirm that in the end is not bad valve deposits cause compression of the valve and cylinder heads for simple cleaning. Cylinder head gasket, seal, and all the old parts, the engine reassembled. Dragging the handle to allow the starter motor is rotated to generate a spark plug mounting hole drain compressed sound. Compression digimaster 3 pressure was measured again, all 1MPa. Start the engine mounted on the spark plugs, the engine very easy to start up.
    This is one case due to the adhesion of foreign objects leaving the inlet and exhaust valves closed undesirable failure, due to the close result of lax compression pressure is too low, and then the engine will not start.
