I'm having the same exact problem. Pooling around intake gaskets, not so milky oil [for some reason every time i check the oil it is just a tad bit more full... not noticable between weeks but overall it'* obvious... but you couldn't tell by looking at the fluid colour]. I can swear I smell coolant burning in the exhaust, but nobody else can smell it. And I blew a lower radiator hose and didn't overheat the car, but it got a lot hotter than it usually does. Ever since then, i've been having these issues. No noticable coolant loss... although like wj every once in a while i'll pop the hood and the overflow tank will be empty. Nadda on the ground, for sure.
wj, I have a feeling our driving habits are similar, and that our problems and solutions are the same as well.
EDIT: oh yeah, I have an idle problem, cold -2500RPM, warm 2k, but if it does that, i shut it off and it'll idle at 1k. Spraying brake clean around the intake gasket does nothing, but there is a ton of grease/oil buildup around it, so my guess is it wouldn't suck it in anyways.
