Advice needed...I have been having overheating problems. This part: http://pg.photos.yahoo.com/ph/robanzellotti/album?.dir=/27f0re2 which sits right over the alternator, started leaking. I pulled it out, and it seems there was some kind of passive valve in there that ain't there any more! I assume it blew forward, in the direction of the straight hole. This goes into a metal pipe that takes you to to the back of the engine (front of the car) and goes into the motor. I checked the pipe, it is clear. Is it stuck somewhere in the block, or did it blow through all the way to the radiator? The radiator seems to warm evenly, so maybe that is a good sign - maybe it is right at the entrance. Or maybe I have it all wrong. I don't have any idea which in direction the water flows. The car is cool as long as I don't take it on the highway. That makes me think there is a partial blockage somewhere, but enough water gets through for low speed driving. Where should I look? Also, I sealed up the part in question with blue RTV and plan to drive it a few days until I can replace it. It the missing valve the whole problem, as it prevents proper flow? If so, what about the lost valve? It had to go somewhere! All suggestions appreciated! Robobass
