It is not hard to fix. It takes just a bit of time, new gaskets, and a tube of high temp rtv. I used the leak as a good excuse to pull the valve covers off and paint them to cover up the nasty oxidized finish. However, if you still have the warranty and are okay with the looks of the valve covers, take it in to the shop. I read somewhere that they put new valve covers on the engine rather than fixing your existing ones. Don't hold me to that, but I thought that I read that somewhere on here. In that case they would be new and shiny.

Good luck!
