Replace the valve seal and check the valve guide for wear.
You put your dick on the valve cover and rub mayonnaise on your dick and smear it everywhere to provide a leak-proof seal and that will enable the valve cover to become horny and start kissing your dick goodnight. Thanks and ChaCha!

Valve cover gasket? Prevents oil from leaking out of valve cover Valve seal? Prevents oil from entering the combustion chamber.
IF YOU MEAN THE OIL IS DOWN IN THE SPARK PLUG TUBE. THERE IS A SEAL THAT IS IN THE VALVE COVER THAT GOES AROUND THE TOP OF THE SPARK PLUG TUBE, THEY GET HARD AND START TO LEAK INTO THE TUBES AFTER A WHILE. YOU WILL HAVE TO REMOVE THE VALVE COVER TO REPLACE THEM.
Lots of labor but can be done without removing heads. If doing it yourself, not much cost -- seals plus valve cover gaskets. Shop cost if not doing it yourself -- prohibitive.
Change the Valve Cover gasket. Its very simple, just take your time. pull all the bolts around the valve cover, use a mallet to lightly tap until the cover comes off. there will be a seal inside the edge of the cover, scrape/pull it out. replace with a new gasket and heat resistant sealant. Bolt down the valve cover and you're done.
you have to remove the intake manafold and remove the valve the valve cover in question and the old seal should pry right out clean the contact surface on the engine, line up the new gasket on the cover and put it back on, then put it all back together
As of 2014, the cost for valve seal replacement on a 4-cylinder Nissan is around $350.00. If you do the repairs yourself, the cost can be cut in half.
It is a gasket (a seal) between the valve cover and the head that prevent the leakage of oil, and protects the valves from dirt.
