I have a really odd coolant leak that I cannot figure out.
I first noticed a vary faint coolant smell, and when I took a look, found a few drips on the ground under the front of the engine. Coolant was dripping down the front of the block from somewhere. Last time this happened, it was the stupid heater core return line o-ring, so I RTV'd the crap out of it to make sure it was sealed. After doing this, I made sure the cooling system was still burped (it was), and added more coolant to the reservoir (to the top of the dots).
I drove it around and after a few days noticed the drips and smell again. When I looked under the hood, I can see where the coolant is dripping down the front of the oil pan, but can't find a single wet spot on the timing cover or water pump. I can also see where coolant has been flung by the belt onto the side of the battery.
The strangest part of it all is that if I put coolant in the overflow tank, it will be empty in a few days.....BUT the cooling system stays completely topped off...to the point that it actually overflowed some last time I popped the cap.
Has anyone encountered an odd leak like this before? I'm not really sure where to look next besides trying UV dye.
I should add that the water pump, T-stat and bypass hose are all brand new as of last fall, so I doubt those are leaking and/or bad.
