Are you referring to the valve cover or the head itself?

Is the valve cover leakage coming from a crack on cover or valve gasket (between the cover and engine)?
If it is coming between the valve cover and engine, then you will need a new gasket. They range between 20-50 bucks depending on vehicle.
If you can not afford one, for a quick fix, but needs to be corrected as soon as can afford. Your able to make your own quick fix gasket using high heat gasket silicone. It would have to cool off completely before adding silicone making your own bead around the contour of bottom of valve cover then sit for a few hours before starting it.
If you can afford a new gasket; remove the old one. It might take a scraper.
Take some sand paper and clean the where the gasket was really good. Wipe clean then add some high heat gasket silicone. then place the gasket on the silicone. Add a bead of high heat gasket silicone to the engine where the valve cover would go, that helps keep it in place when screwing the screws back on.
If you leakage is coming from a cracked valve cover, i would advise replacing it. I am sure you could find a used cheap one at a local junk yard.

Good luck and hope this helped.

no u don't, u do that from under the car.

undo all the mounting bolts on the top, remove plug leads, give it a hit with a soft mallet to free the rubber gasket, use a new gasket when replacing

i would just try puting new gaskets in where it is leaking

Are you sure its the oil pan most leaks come from the valve cover gaskets up above. check the corners of the valve covers. If the pan needs re-sealed you will have to remove the flex pipe.

Replace the half round rubber gromets at the cylinder head ends just under the gasket you replaced

REMOVE THE INTAKE. ROUGHLY 2.2 HOURS FOR THE JOB. ORDER THE VALVE COVER GASKETS WITH GROMETS.
