Engine oil pump is blocked when the chain would ring
1, the phenomenon is generally rhythmic sound, the sound is on the side of the camshaft, the noise is more than when the gear meshing uneven sound sharp. At low engine in speed, sound obvious and clear; increase the solar term door opening, the sound increases and becomes messy. In a few cases, a very heavy "click" sound can be heard, as if the camshaft bearings are seriously loose.2, reason oil pump shaft, distributor drive shaft bending or axial clearance is too large: oil pump drive main and driven gear, distributor drive, driven gear, crash or wear and tear deformation.3, check and judge this sound "fire test" test is invalid, you can touch the stethoscope at the lower end of the distributor body auscultation. If the noise is obvious, the body has a slight vibration, can be repeated from idle to low, medium speed throttle test. If the sound changes, as mentioned above, it may be this sound. If you hear a heavy click or click, as if the camshaft bearings are loose and loose, it is possible that the oil pump is broken.
