Thanks again. Another dumb question: is it possible that there would be oil leaking
Where these gland nuts attach to the supercharger case?
Scooter--
The intake induction tubes alternately operate at both positive and negative pressure (compared to ambient) so leaks are either blown out of the tubes by positive supercharger pressure--when manifold pressure is above ambient at full throttle/high RPM--or you may have a leak from somewhere else that is showing up on the tubes. At lower manifold pressures (below ambient) you will be sucking air into the tubes through any leaks, leaning the fuel/air mixture. While there is obviously oil in the supercharger section to lubricate the parts, oil coming out of the tubes could be an indication of an internal oil leak in the blower section. What I would expect to see normally is fuel stains from the fuel/air mixture going from the supercharger to the cylinders--shouldn't be much oil in that mixture. A more likely source of oil would be leaking rocker box covers, or from cylinder bases, with the oil blown back onto the intake tubes/blower section, or from something leaking in the accessory section.
