I knew it was leaking and have checked all the likely candidate, water pump, water pump o-ring, the drain valve on the block and the head gasket.

I have a very slow drip that comes off of the passenger side front bolt of the transmission bolt. There is a oil cooling line just above it, but why the feck would coolant be leaking from that? I cannot find any leaks from the motor other than motor oil from the front timing cover.

I like this car but I am pretty frustrated with this one. It looks and runs great and it doesn't overheat but it is losing coolant and if I took it on a an extended trip I think it would eventually get low enough to be a concern. Just trying to make it right or at least better.
