Why Does the 408 Burn Engine Oil After Replacing the Timing Belt?

[KaydenLynn]

408 burning engine oil after replacing the timing belt is due to issues with the valve oil seals. The valves are essentially designed to prevent engine oil from leaking into the combustion chamber. However, over time, the sealing performance of the valves can be affected, making it easy for engine oil burning to occur. Additional Information: 1. Function of the Timing Belt: The timing belt serves as a crucial link, connecting the timing wheel on the upper part of the engine cylinder head to the timing wheel on the crankshaft below. The timing wheel is connected to the camshaft, which has cams. The contact point is the small rocker arm, which generates pressure through the power transmitted by the timing belt, serving to lift the valves. 2. Role of Lifting the Intake Valve: It allows atomized gasoline to enter the cylinder. When the exhaust valve is lifted, it allows exhaust gases to exit the cylinder. When the recessed part (note: not the raised part) of the camshaft simultaneously contacts the small rocker arm, both the intake and exhaust valves close, creating compression. The distributor then sparks, initiating internal combustion and generating power.
