Hmm... interesting predicament you have there....
Ya, I'm looking at the manual & parts list right now, but I'm not sure if I'm seeing it... I replaced the t-stat in march. There's the t-stat housing that holds the t-stat w/ gasket, and then doesn't that just bolt directly to the block, or is there another section that the t-stat housing bolts to which in turn bolts to the block? It looked like it was leaking from about 1" behind the t-stat housing... I'm getting a little worried looking at parts list, right now... I don't see another gasket where I saw the leak. maybe it was just bubbling out of the t-stat housing gasket? crap.
