Default Re: Hello, new G9 owner, need help...pics inside!

There is a port coming from the front, (down low). That is the port for vacuum, to run the fuel pump. But there needs to be a check valve (in that line), to draw oil from the port on the back of the motor, up to the port on the back of the valve cover. That line on the back of the motor, is oil supply to the rocker galley. That check valve is just above the little (white) twisty, in the first pic. (passenger side of the valve cover).

Search; "Stepper oil supply". Smallblock!!

It is imparative, that the air box be assembled correctly, and sealed from any air leaks. Except at the snorkel.
