Help...My dealer is clueless!!!

I had a slight oil leak from my valve-cover gasket and my dealer "fixed" it. Four weeks later, oil (I thought) started to appear on the floor (prior no oil on floor, just on engine). Took it back when I saw "oil" on top of the valve cover in the grove. No evidence of spray anywhere in the engine compartment. Dealer said I dripped oil down the engine when I was adding oil (needs new valve seats too!!). They cleaned the engine. Over the next few days I started to create larger spots. However, the fluid is not oil it's anti-freeze on top of the valve cover. Again, no evidence of spray in the engine compartment??

Dealer has had my car for 1.5 days and can't find the leak. In fact, the latest update is they have made it worse as it now has oil in the #4 spark-plug socket. They are pulling the valve cover again as I type. I wanted to get my valve seats fixed (while they have the cover off again), but I have zero faith in my dealer!!!

Anybody know where the leak might be coming from (cracked cover?)

Thanks,

Scott
