Ingabe ikhava ye-valve iphukile
Ngokuvamile kunezizathu ezimbalwa zokulimala kwe-valve cover gasket. Esokuqala ukuthi ibhawodi lixega, okwesibili ukushaywa kwenjini, okwesithathu ukuqhekeka kwesembozo se-valve, kanti okwesine ukuthi i-gasket yekhava ye-valve yonakalisiwe noma ayivalwanga nge-sealant.
Ngesikhathi sokucindezelwa kwenjini, inani elincane legesi lizogeleza liye ku-crankcase phakathi kodonga lwesilinda neringi ye-piston, futhi ukucindezela kwe-crankcase kuzokhuphuka ngokuhamba kwesikhathi. Ngalesi sikhathi, i-valve ye-crankcase ventilation isetshenziselwa ukuholela le ngxenye yegesi endaweni eningi yokuyidonsa bese uyihogela ekamelweni elivuthayo ukuze iphinde isetshenziswe. Uma i-valve ye-crankcase ventilation ivinjiwe, noma imvume phakathi kweringi ye-piston kanye nodonga lwesilinda inkulu kakhulu, okuholela ekushintsheni komoya okweqile kanye nokucindezela okuphezulu kwe-crankcase, igesi izovuza ezindaweni ezinokuvaleka okubuthakathaka, njenge-valve cover gasket, ama-crankshaft ama-oyela angaphambili nangemuva, okuholela ekuvuzeni kukawoyela wenjini.
Uma nje usebenzisa i-sealant, qinisa ama-bolts, futhi ikhava ye-valve ayiqhekeki noma ikhubazekile, ibonisa ukuthi isembozo se-valve sihle. Uma ungakhululekile, ungasebenzisa irula kanye negeji yokujiya (igeji ye-feeler) ukukala ukucaba kwekhava yevalvu ukuze ubone ukuthi ayiwohloki yini.
