Re: IML: Heat riser rotation?

[sosmi@xxxxxxxxxxx]

NOT a dumb question, If memory serves me correctly, the valve rotates clockwise. There should be a stop pin which prevents the valve from opening past center.If you feel a lot of restriction opening the valve, its possible to break the spot welds on the valve, and it will remain shut.If you have dual exhaust, have someone listen to the right pipe for a louder exhaust sound, when you open the valve.This is one of the simplest issues for performance, and mileage that goes un-checked.When we remove the manifolds, we remove the valve completely.Ya'll have a nice day, Dave.
