Ce que couvre cette vidéo
Timo and Jo of NV perform a marine diesel engine head rebuild in Borneo after discovering a warped head and corroded valves.0:04 The crew removes the head and transports it to ES Jesselton Engineering for professional machining.11:55 Technicians use a straight edge and feeler gauges to confirm the engine cylinder block remains flat, isolating the damage to the head.3:50 The machine shop resurfaces the head and machines the valve seats to accommodate new valves.5:35 During the process, the team identifies corrosion likely caused by a faulty heat exchanger and a previous period where the engine sat partially submerged in water.6:21 After initial assembly, a compression test reveals two valves failing to hold pressure, requiring additional seat machining.10:14 The team successfully installs the valves and secures the springs with keepers.10:44 Proper machining of the head and valve seats restores compression, though the crew continues to monitor the engine's long-term viability.5:35
