What is the torque for the cylinder head screws of the Peugeot 408?

[VanJuniper]

The torque for the cylinder head connecting rod cover and crankshaft cover screws is 8 for the large bearing cover and 6 for the small bearing cover. The compression ratio of each vehicle model's engine varies, so the torque of the bolts is different. You can use a torque wrench to measure the torque in Newton meters when removing the screws. It is best to follow the data provided in the manual for maintenance to ensure quality standards. Here is more related information: Engine cover: 1.
