At present changing my standard breather system to Bailey.

Just removed the left hand side of the rocker cover to metering unit plastic breather pipe.

After I done this I noticed that the smaller pipe that runs from the metering unit to 'R' of the amal is attached to the metering head and then vented to atmosphere.

I am running a bleed valve in-line between the actuator and wastegate with amal not used.

Should the hose that should be coming from the metering unit to the 'R' of the amal, be blocked or is atmosphere OK?

Next question, at the top of the metering head the take off on the RHS is larger than the LHS. I would like to use both sides to remove some T-Pieces. Does anyone have the smaller LHS take-off for sale, that I can use to replace the larger RHS?
