If discover engine oil has been used up much, should burn from what examine leak two respects proceed with.
Check above all the oil that do not have leakage is in, oily to crankshaft front and back end leakage place and gasket of the carapace end oil and engine oil filter are in microscope, specific course of action is to open clutch to check Kong Gai, observe flywheel bottom has inorganic oil, if have engine oil, because oil seal of crankshaft back end is undesirable,be likely cause oil of leakage of crankshaft back end. Tear open next starting claw, examine front of crankshaft leather belt whether is organic oil kept inside aperture, if be put in engine oil, show ageing of caustic of Cuba of crankshaft front oil seal or crankshaft leather belt annulus and surface of oil seal contact wear away to cause leakage oil badly, mat asbestine rope can be added to jam in starting claw end to this leakage is oily.
The bad news oil that if not be leak,causes is overmuch, that should check engine oil to whether be burned by inspiratory firebox. Specific course of action is to increase accelerator high speed to run, mist of if vent-pipe eduction is many thick blue smoke, add engine oil mouth to be in a large number of fume or pulsatile fume at the same time, explain engine oil enters firebox. Engine oil enters the reason of firebox, it is the cylinder bushing of engine oil edge inside crankcase enters firebox, 2 it is clearance of conduit of valve of room of valve of engine oil edge enters firebox. If high speed runs, vent-pipe risks thick blue smoke, and increase engine oil opening place is not fumy, criterion engine oil most is from gas cylinder bushing upside enters firebox, the likelihood is spiracle conduit rupture or be caused by of invalidation of spiracle oil seal; If vent-pipe risks blue smoke to add engine oil mouth to be in a large number of fume or pulsatile fume at the same time, explain engine oil enters firebox from air cylinder bottom, but the working circumstance according to engine, judgement gives the specific reason that burns engine oil. If burn engine oil, but engine job is basic and regular, may be screwy annulus or cone-shaped annulus assemble fashionable dress to turn over. If burn engine oil while companion has engine power to be not worth, it is piston and crock wall space more too big, piston annulus grinds loss effect or piston encircle reachs place of speak or sing alternately to cause to death. If vent-pipe is fumy serious, from dipstick the canal is in change engine oil, because crankcase connects air-valve or crankcase airway compulsively to jam,be commonly, create crankcase pressure exorbitant cause.
