Default 2000 Accord 4 Cylinder Coolant Leak

Recently Iíve noticed an antifreeze leak in my 2000 Accord LX 4 cylinder. I only see it when the car sits in the garage for a few days. Recently I parked it once for four days and once for a week. On both occasions there was a little puddle under the car. When I park it overnight, there is no puddle. The car does not overheat. There is some residue on the back of the engine on the driverís side. The car currently has almost 140k miles on it. Back around 105k (two years ago) I had the timing belt and water pump replaced by the dealer. At first and occasionally after, I noticed a slight antifreeze smell when I pull the car in the garage. Since it wasnít overheating and didnít seem to lose any fluid, I ignored it. Now apparently itís getting worse. Is this something to worry about? Iíve read a couple of other posts about a weep hole. Maybe thatís all it is? Thanks in advance.

I took it to the dealer last week and they did a pressure test. They didn't find a leak. They could see the residue and checked everything for tightness. I guess we'll see next time I park it for a few days if it's still leaking. Any other ideas?

Can you post a photo of where the coolant is seen on the engine?

Here are a couple of pictures. I'm not sure you can see very much though. It's on the driver's side on the back of the engine.

Go to one of those spray car washes and clean it up. Put a piece of white paper (whatever?) under, watch and see where it drips. Lay down under (get it up a little) with a good light and check. If it was pressure tested, this is weird.

Your second picture if what I am looking at is the coolant trail looks like it starts high up and is in the cylinder head area. Can you get a mirror and see where it starts.
