Just changed head gaskets on a 83 zxt. Naturally dropped the timing chain so had to pull the timing cover also. Got it all back together and she runs BUT i'm leaking coolant out of one of the timing cover bolts. It is on the passenger side up close to the head and holds the alternator tensioner arc arm as the stationary point. Anyone have an idea why this is happening and what to do about it. Tried putting some rtv on the bolt and retightening but didn't stop the leak. Don't know what the status was before the new head gasket as I bought the rascal cheap not running but supposedly running until the head gasket went at about 195k.

any help appreciated.

I don't have any of my timing covers off right now to look at them, but I think that bolt goes through what should be a sealed passage. So I don't think it should leak unless either a.) the timing cover is cracked where that bolt goes through; or b.) there is something preventing the timing cover from sealing properly against the front surface of the block.
