Thanks Circ. Here's an update - I just finished driving it like I stole it, per the seafoam instructional post I found. When I finished, I looked again where the ''leak'' was/is and whatever it was had burned off of the manifold. I ran it for a while in park then shut it off and kept and eye on the manifold for signs of the leak and saw nothing. I also ran my fingers along the valve cover gasket and didn't get any oil on my fingers. The dealer I bought it from had done a fresh valve cover gasket change before I bought it because they were leaky. You can see the fresh gasket sealer that oozed out of the seal. I don't think they are leaking. So this mystery fluid could be something else.. Any idea what else is between the valve covers and the exhaust manifolds that could be leaking?? I'm thinking the fluid may have been the seafoam itself. Maybe the intake plenum gasket is leaking??
