That'* not the LIM gaskets leaking, that'* the coolant elbow. Those cost about $5.

Directly above the waterpump you say. That'* either waterpump gasket or coolant elbow. Reason behind that is the LIM gasket there is sealing in oil from the lifter valley. The only coolant at that end of the motor that could leak that way is from pump or elbow. Unless you blew out part of the tensioner bracket and it'* leaking from there.

Nice thing is if it'* an elbow or tensioner you are lookin at a 30 min fix.

Right, and you can find those in the Help section of most auto stores. There are actually two elbows in the kit since there are two you can replace right next to each other.

Technically being a 96, he'll have one plastic elbow and the other is part of the alternator bracket/tensioner assembly. Sounds like he'* pretty sure it'* not that though. This one is peaking my curiosity.
