有缺陷的阀门或密封指南,从上方穿过阀后代的油潜行,并落入压缩室内。用Carbonilla填充所有东西,并在里面收集污渍。但是我不为通风口吹!您会发疯,直到失败为止。
Anyway, these seals are changed when you are cooked to avoid this problem, just as the cylinder head is planned, it is checked under if there are cracks, the slack of the valves of the valves inside the guides is checked ... in the end, rectifying works when you have to lift a cylinder head, the same as if you disassembled pistons, it is normal to put a game of segments (piston rings) connecting rod and bench, which does不代表很大的费用,但会导致您一个非常胖的问题。
一切顺利。
