Kodi chivundikiro cha valve chasweka
Nthawi zambiri pamakhala zifukwa zingapo zowonongeka kwa valve chivundikiro cha gasket. Choyamba ndi chakuti bolt ndi lotayirira, lachiwiri ndi injini yowomba, lachitatu ndi kuphulika kwa chivundikiro cha valve, ndipo chachinayi ndi chakuti chivundikiro cha valve gasket chawonongeka kapena chosatsekedwa ndi sealant.
Panthawi yoponderezedwa kwa injini, mpweya wochepa umadutsa ku crankcase pakati pa khoma la silinda ndi mphete ya pistoni, ndipo kuthamanga kwa crankcase kumakwera pakapita nthawi. Panthawiyi, valavu ya crankcase ventilation imagwiritsidwa ntchito kutsogolera gawo ili la gasi kumalo ambiri omwe amalowetsa ndikulowetsa mu chipinda choyaka kuti chigwiritsidwenso ntchito. Ngati valavu ya crankcase ventilation yatsekedwa, kapena chilolezo pakati pa mphete ya pisitoni ndi khoma la silinda ndi yayikulu kwambiri, zomwe zimapangitsa kuti mpweya uziyenda kwambiri komanso kuthamanga kwambiri kwa crankcase, mpweyawo umatuluka m'malo osindikizidwa ofooka, monga chivundikiro cha valve, crankshaft kutsogolo ndi kumbuyo kwa mafuta osindikizira, zomwe zimapangitsa kuti mafuta a injini atayike.
Malingana ngati mumagwiritsa ntchito chosindikizira, sungani ma bolts, ndipo chivundikiro cha valve sichikuphwanyidwa kapena kusokoneza, chimasonyeza kuti chivundikiro cha valve ndi chabwino. Ngati simuli omasuka, mutha kugwiritsa ntchito chowongolera ndi choyezera makulidwe (feeler gauge) kuyeza kusalala kwa chivundikiro cha valve kuti muwone ngati sichikupunduka.
