That's a good tip fasteddy. Hey stevec, if you are going to take the valve covers off, you will essentailly be at the same point as my picture from earlier. You may want to see if you have coolant in the intake as you see in my photos.

According to your post, it seems like it is a really slow leak, so you may or may not find anything. It wouldn't hurt to look though.
