4 operation tips for the cylinder head cover gasket

1. Replace the component if, having demounted the valve cover, you noticed that the cylinder head cover gasket hardened, and there are cracks or tears on its surface.
2. Do not use a sealing compound for installation of the cylinder head cover gasket if this is not prescribed by the manufacturer.
3. In order to ensure proper sealing, tighten the fastening bolts of the cover according to the specified layout and with the torque indicated in car technical documentation.
4. Always check condition of engine sealing elements, including gaskets of the cylinder head and the valve cover, if the engine was overheated: under the influence of high temperature they may melt on the surface or be deformed.

Defects of the cylinder head cover gasket, their signs and causes

1. Loss of material elasticity. Usually it is caused by natural aging of rubber, influence of oil and temperature changes, usage of improper sealing compound, etc. It is easily detectable during visual inspection. Oil stains on the surface of valve cover or even on the dust boot of an inner CV joint can indirectly indicate that the connection tightness is lost.
2. Tearing and cracking. It is mostly caused by improper torque of tightening of fastenings, poor quality of the component itself, or deformation of the surfaces of the cylinder head and its cover. As in case of hardening, this defect may be suspected by increased oil consumption, stains of lubricant on the engine parts surfaces, under the car or in spark plug wells, as well as by smell of burning in the passenger compartment.
