Should the Engine Cylinder Head Gasket Be Replaced if It's Slightly Seeping Oil?

[DiCharles]

Engine cylinder head gasket should be replaced if it's slightly seeping oil. More than 90% of oil leakage problems are caused by rubber seals losing a large amount of plasticizers and softeners due to prolonged exposure to alternating hot and cold temperatures, leading to corrosion, aging, and hardening of the seals. Initially, it may just be oil seepage, but over time, oil dripping can occur. If left unattended, the seals may eventually break, necessitating replacement. An engine is a power generation device and can also refer to the entire machine including the power unit (such as gasoline engines, aircraft engines). Types of engines include internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), gas turbines (used in racing cars), and electric motors.
