Ingaba isigqubuthelo sevalvu saphukile?
Kukho izizathu ezininzi zokonakala kwegasket yesigqubuthelo sevalvu. Esokuqala kukuba ibolt ikhululekile, esesibini kukubhudla kwenjini, esesithathu kukuqhekeka kwesigqubuthelo sevalvu, kwaye esesine kukuba igasket yesigqubuthelo sevalvu yonakele okanye ayigqunywanga ngesitywina.
Ngexesha lokuxinwa kwenjini, inani elincinci legesi liya kuphuma liye kwi-crankcase phakathi kodonga lwesilinda kunye neringi yepiston, kwaye uxinzelelo lwe-crankcase luya kunyuka ngokuhamba kwexesha. Ngeli xesha, i-crankcase ventilation valve isetyenziselwa ukukhokela le nxalenye yegesi kwi-intake manifold kwaye iyiphefumlele kwigumbi lokutsha ukuze isetyenziswe kwakhona. Ukuba i-crankcase ventilation valve ivaliwe, okanye indawo ephakathi kweringi yepiston kunye nodonga lwesilinda inkulu kakhulu, nto leyo ebangela ukuba umoya ujikeleze kakhulu kwaye uxinzelelo lwe-crankcase luphezulu, igesi iya kuvuza kwiindawo ezine-sealing ebuthathaka, njenge-valve cover gasket, i-crankshaft front kunye ne-oil seals zangasemva, nto leyo ebangela ukuvuza kweoyile yenjini.
Ukuba nje ufaka i-sealant, uqinise iibholithi, kwaye isigqubuthelo sevalvu asiqhekekanga okanye asiguquki, oko kubonisa ukuba isigqubuthelo sevalvu silungile. Ukuba awukhululekanga, ungasebenzisa irula kunye negeyiji yobukhulu (feeler gauge) ukulinganisa ukuba isigqubuthelo sevalvu sithe tyaba na ukuze ubone ukuba asiguquki na.
