    I got an oil leak and the cause of it is the valve cover gaskets. the problem is that I just replaced them 20 min ago and problem still exists. I don't know if I should have used sealant or not but it's leaking front the front valve cover to the right side of the first fuel injector from the left. what can I do? please help me.

    Did you replace them with the gasket and gromments?

    Did you clean off all the old oil that has been leaking from the front cover? If not, then every time the car heats up the old oil will turn liquid again and run down. Clean the crap out of the head, LIM and exhaust manifold and then see if you spot any fresh leaks.

    And no, I would not use any sealant. These covers are designed to be used w/o sealer.
