Car oil leaks from valve cover gasket?

First of all,if the valve cover gasket is blown and oil is leaking then replace valve cover gasket.

But if gasket is already replaced and still you notice same oil leak from valve cover gasket after few weeks,then this is indication that you are using cheap low quality auto parts.The valve cover gasket which you replaced may be of low quality auto part.And other possibility for same reason is faulty PCV valve.

A Positive Crankcase Ventilation (PCV) valve.

Check the PCV valve.If its clogged or gunk-ed up with dirt then this is the reason of oil getting leak from valve cover gasket.

Basically PCV valve is on valve cover itself.The purpose of PCV valve is to vent the extra pressure getting created in the engine.If this pressure exceeds then valve cover gasket will be blown up.So inspect the PCV valve.Its very cheap part.And should be replaced on every engine tune up period.

Always use good branded parts.Dont use third grade cheap quality parts.They are cheap,but dont give exact results.

This details will help.Thanks,.
