for both of you posters above!
i would definatly always get a new gasket, especially for engine pieces, BUT (this is the important parts...)
when i painted my valve cover, i bought a new gasket and everything, and put it back on...didnt notice any problems untill yesterday...i opened it up to check the spark plugs and their was an oil puddle around all 4 spark plugs!
turns out when i put the valve cover back on (with the new gasket) i over torqued the screws which actually causes the gasket to stretch out...(do to the pulling effect i guess)..of course their is no way to know that i did this untill you check something out under the cover again (ie spark plugs)...
anyways point is... DONT MUSCLE DOWN THE CAM COVER BOLTS! the rubber will create a good seal without a lot of force so just snug them down, but not too much as you dont want to stretch out the gasket!
also when you replace the cam cover gasket make sure and thorouchly check the rubber rings on the bolts...mine were totally effed up and i didnt notice it untill yesterday also! you can buy the rubber bolt seals fairly cheap and it might help a lot with sealing the cam cover down...
for the price i wouldnt over look it like i did last time!!!
