You should not remove or fit a dump valve that exhausts to atmosphere on these engines (if I understand the question correctly). The air is accurately measured and any exhausting to atmosphere can cause errors. Removing altogether on a standard AAN could cause the turbo to stall which is why the valve is there in the first place. Best option is to replace with an equivalent Forge recirculating dump valve.

Get one from a dealer for the price of them. They are better quality.

Would only buy froma reputable source. the bailey type ones are ok but need servicing every yrar or they fail.

have a 710n fitted By MRC when it had the health check and it sounds ace and has given me no grief
