Default '94 LT1 freeze plug leak

This is a new one for me. Had the car on the lift, searching for a small coolant leak. It's coming out of the freeze plug behind the motor mount on the left side.

Probably going to suck a little bit to change it.

Is this common on LT1's ? The block otherwise is clean, and the other freeze plugs are not even oxidized. This one is rusty and leaky (had to use my flexible camera to see it).

Looks like I gotta take the manifold off, motor mount, and jack that side of the engine up a little bit. Fun.
