Dave called and said oil was leaking onto his pants from underneath the dashboard. Tom and Ray said it was a leaky seal in the speedo-cable, allowing xmission fluid to come up the cable and drip onto Dave’s Dockers.
But doesn’t this violate the laws of physics? After all, the transmission is considerably below Dave’s leg. Can oil really flow uphill?
I’m guessing there must be some sort of Archimedes Screw effect pumping the oil up the speedo-cable as the shaft turns. But for this to happen, the speedo-shaft would have to be helically shaped, like a spring, and oriented in the right direction for pumping action, clockwise or counterclockwise, right?
My question: Wouldn’t the manufacturer orient the speedo-cable helix so that as the cable spun, it would push the fluid back down into the transmission, instead of pumping it up the cable? Help! Help! This has been bothering my poor brain!
