    Just bought the car and fixing some of the problems. Driving around i noticed the temp guage climbing so i headed home to see what the deal was. I was low on coolant and could hear a hissing noise from the back right side of motor. Located under the throttle body and back i was thinking head gasket. Checked oil its good and so is my radiator fluid. I let the car idle and stood back and noticed the leak and pin pointed it to this piece close to this donut looking piece lol heres a pic of the leaking area

    No they need replaced. It's kind of a pain on the 3100 but it's doable. It's close to a $1000 job at a shop.

    The kit from autozone has the upper and lower valve covers and thermostat gasket. But you should just replace everything while it's getting done.

    i put it on the back right manifold screw because i could not remember where it was and it was the only spot i could think of.... I am also missing one of the screws that are black and on the valve covers. autozone does not have info on it but i was wondering what size it is so that i could buy a replacement???

    Put some teflon paste on there and hope it seals it up. I'm thinking there is a rubber o ring in there thought that might have torn.
