So about 2 months ago my 94 cobra's stock water pump finally went on the way to work, I made it the short way to work and the temp gauge was high but the car didn't seem to be in any danger. It wasn't boiling over or anything, from there I towed it home got a new water pump and had it fixed within a day... Since then I had been noticing small pools of coolant on top of the water pump, one below the thermostat housing and one the right of that in the little valley to the right of distributor. Well noticed a small leak from the thermostat housing, fixed that thinking it would alleviate the problem, and it did to a point. The puddle below it was gone, but the one to right was still there. From there I inspected and noticed the lower intake gasket seemed to be wet on the valley, so I look my upper and lower intake gaskets off looked for possible cracks put on new intake gaskets and a nice thick bead of ultra grey rtv on the front and back intake valley along with water jackets. So that bring me to now, The puddle is still appearing after sitting for a couple days, I cannot pinpoint any spot where it it coming from, and seems to be a very slow leak.. The headgaskets were recently done, and I dont see and cracks in the heads(aluminum gt40x). Ive gone around tightening heater hoses, radiator hoses, etc... And cannot seem to find where it is coming from... at this point I thinking about getting a pressure tester to see if i can track down the leak like that, but any other suggestions would be appreciated.

Possibly around the t'stat bolts?
Pressure tester would be a good, it would be like watching paint dry tho. But I guess you have no choice.
I would probably replace the short 90* hose, it could also be the t'stat housing where that short hose connect to.

it's definitely not t-stat related. I sealing that thing up like a submarine. And i put a rag there to see is anything would leak down into the rag and the leak is confined to the right of the water pump.. Im gonna pressure test it before i go ripping my timing cover off, however that seems to be the most logical place seeing that coolant runs through at that spot.
Had this problem. Ended up being the coolant tubes. Theres 2 o-rings inside of it. Mine were shot and allowed coolant to seep out. Might be able to find a write up on stangnet.

This was going to be my suggestion, to check anything related to the oil cooler lines.

have you had time to found the leak yet?
yes i have, sorry for not updating this post... but i resolved most of my issue with a new heater hose, old one was cracking and dripping coolant between the motor and bell-housing, and would run to the front of the motor... however the pressure test did reveal a leak in the timing cover, however its small enough to the point that I wont see any real accumulation for a couple days, and even then its drops at max... so I am going to monitor it and eventually fix it when I absolutely need to.
