If the coolant leak was coming at the fitting or hose for the heater
core, it would be leaking at the back of the block. It's not. It's
leaking on the upper left side, and the coolant pours down that side as
well, not dowm the trans bellhousing. From what I can see, the source of
the leak it appears to be a black or dark projection coming out of the
upper back left side of the block. If I could get this up on a lift and
pull the left side exhaust header, I could see where the leak is and
know what it takes to fix it. But this is a driveway repair, so knowing
in advance what the leak origination point could be would save a lot of
grunts and banged up knuckles. I could save them for the actual repair.

I sold this V8-Quattro six years ago, and I'm still dealing with it
because the owner is an old friend. Always sell a V8 Quat to an out of
town stranger (though I had six perfect years with it).
