Default Quick coolant leak question!

Hey guys, just making this thread to get a quick answer. Anyways, my car is leaking (dripping every couple seconds) at the rear of the engine more on the drivers side. Its very annoying, and I cant seem to find the source ANYWHERE up top. My hands also dont come up wet with coolant when feeling the rear of the engine area (scientific I know). I saw a thread awhile ago about a leaky o-ring in the water inlet housing causing coolant to drip into the intake valley, and running out the back of the engine through the drain holes. Make sense that it might be the issue? The car has almost 190k on it

Its a 1999 GS400 for the record.

i know you said you have felt around but have you actually tried jacking the car up and looking for the leak? i mean if its leaking a few drops every second it shouldnt be to hard to find....wear some googles so it doesnt get in your eyes

I have a weird feeling that might somehow be the culprit even thought the drip appears to be at the rear of the engine... Can coolant get into the intake valley and run out the rear from the pump? Thursday I'll know, dropping it off to get looked at. I don't have the means to lift the car at my house
