I forgot a potentially important piece of information.
I didn't wait for the engine to get up to operating temperature before
testing because I was worried of messing something up. I ran it for 20
seconds or so... it was smoking and dripping as before, and then tested
it. Could doing it with the engine "cold" be throwing my numbers way off?
Thanks as always,
Wes
