Have you checked your hogger suction isolation valve. Your air leakage may be coming from your hogger exhaust piping leaking through the isolation valve. We had this issue. When we removed the valve for inspection we found that there was a failure in the valve seat. This failure caused damage to the valve disk. Further investigation revealed that the valve was not properly rated for vacuum.
