Where does hose #66 (Port balance tube) connect to on V4 1996 E90SLEDR Ocean Pro?
a disconnected vacuum hose stuck into the air silencer! My OL Manual said replace hoses every 5-7 years. So I started checking hoses & discovered the disconnected balance tube. It was pulling a good vacuum. I got a generic online manual which does show the starboard balance tube connects to a fitting at the lower crankshaft bearing, but it does not show where the Port balance tube #66 should be connected.
