 I have the same problem.
Well.......the cost of the valve cover gasket and the spark plug seals are very cheap. I got mine from Pelican and cost under $30.00 for all including shipping.
It will take roughly 2-4 hrs of labor, I will be doing the work myself as I'm going to paint the valve cover in the process. It's an easy but tedious work as thee are a lot of parts to uninstall, such as my strut brace, the coil pack, the AC/Heat Filter cover to make room.
I just replaced my water pump, thermostat and belts within 2hrs; I don't know how capable or willing you are of doing your own car work.
A mechanic will easily charge you a couple of hundred dollars (or more) just to do the work to replace parts that are only $30.
Good Luck __________________
