All I can say is that Mongol in Mexico blew a head gasket.

我只能说，在墨西哥的蒙古人盖。

Except for the brakes, rear axle, cylinder heads.

就是刹车 后桥 气盖有点毛病。

The fresh water is circulated through the engine to cool the cylinder jackets, cylinder heads, exhaust valves and turbo-blowers.

新鲜水在发动机内循环，用于冷却气套、气盖、排气阀增压器。

So he did timing chains and guides and did head gaskets and all that, and it still doesn't run right.

于是他更换正时链条导轨， 还做盖垫片等，但车子依然运转不正常。
