Allow me to clear up some stuff.
8th character of vin L is the motor designation L27. This is the motor in your picture and is naturally aspriated series 1.
8th character of vin K is the motor designation L36. This is the motor found in 95+ Naturally apirated bonne'* and called series 2.
8th Character of Vin 1 is the motor designation for L67. This is the supercharged motor whether series 1 or 2 Odd they did it this way...but they did.

Easiest way: L67 has a supercharger, L27 has a black plastic upper intake. I've heard that they can leak (UIM on L27s), while obviously not a common problem like the series to Vin K engines (L36).

And I agree, anything is possible. My question then becomes, where is this coolant coming from? Shouldn't all the runners be like this if the upper intake was leaking coolant internally?

on the upper intake was or is there a tube that runs to the front of the intake for the PCV vapors? I'm guessing not?
The PCV vaoprs may have gone through Cylinder 1, leaving that runner cleaner... A possibility...
Coolant, well thats a possibility as well, but it doesn't look that way

Yep, I forgot about the 92 L27'*.
