I've got a 93 4runner with the 3vz v6 and 5sp, with 160k on it. After my truck overheated this week I noticed coolant leaking out from underneath the timming belt cover. I assumed it was the water pump and went ahead and replaced the waterpump, thermostat, and timming belt. I put it all back together and was very sad to see that my leak was still there when i started it. Could there be a leak on the engine block that runs down there? like maybe the gasket between the block and the head, or the head and the intake? or maybe I just screwd up putting my water pump on? The truck is at a shop now, so i will get an answer soon, but I would like to hear what some others thought about this. will post the answer as soon as the shop tells me,

 

Turns out there is a seal behind the upper idler pulley for the timming belt (where the upper radiator hose connects). It had gone bad, too bad I didn't think to check this while I was inside, now its gonna cost me 490 bucks. I would have waited and tried to do it myself but I am moving to Ohio soon and I am trying to get everything in order and really don't have much time. Maybe I shouldn't have posted this in the newbie section?...I don't know I am new to this site. If anyone has had a similar problem or knows anything about it let me know.
Thanks
