IMP: Cha. Ukusebenzisa i-sealant ngaphandle endaweni evuzayo evuzayo kuzohluleka cishe ngokushesha. I-backpressure ye-exhaust yangaphakathi izophusha kalula ku-silicone ephulukisiwe. Kumelwe ukhiphe i-manifold, ulungise izindawo ezingaphezulu, futhi ufake i-gasket ebonakalayo efanele.

Q: Kungani injini yami ekuqaleni ingazange ibe ne-exhaust manifold gasket?

IMP: Abanye abakhiqizi abadala basebenza ngomshini i-cast iron multifold kanye nebhulokhi yenjini ngokunemba kangangokuthi bavala insimbi iye kunsimbi iqonde embonini. Ngokuhamba kwesikhathi, i-heat warping yenza lokhu kungenzeki ukuphindaphinda, okudinga i-aftermarket gasket ukuze ilungiswe yesimanje.

Q: Ingabe i-copper spray ingcono kune-silicone yokukhipha ama-gaskets?

A: Yebo. I-Copper spray-a-gasket yakhelwe ukumelana nokushisa okudlulele kufika ku-1,500°F. Isiza ukugcwalisa ukungapheleli okubonakalayo kwe-microscopic ku-pitted cast iron ngaphandle kokululaza, umlotha, noma ukuphephetha njengemikhiqizo yokuvala uketshezi esekwe ku-silicone ngaphansi kwamazinga okushisa aphezulu.

Q: Ingabe ama-multifold exhaust olwandle adinga ama-sealant ahlukene kunezimoto?

A: Yebo. Izinhlobonhlobo zasolwandle ezipholiswe ngamanzi zisebenza emazingeni okushisa aphansi kakhulu ngenxa yokugeleza kwamanzi aluhlaza. Nakuba i-silicone ingase iphile, usimende we-marine gasket okhethekile akhethwa kakhulu ukuvimbela ukugqwala kwe-galvanic kumajakhethi amanzi kuyilapho ehlinzeka ngophawu oluthembekile.
