Check Engine Light Due to a PCV System Vacuum Leak on Lincoln Town Car

A vacuum leak from the PCV grommet vacuum leak can cause the Check Engine Light to illuminate. The molded rubber hose connections may crack and collapse, causing the vehicle to run roughly. A damaged PCV hose will require replacement.

I have had all four cat. converters replaced, colored gaskets all replaced. The code reads problem with left bank. It's been on for two years and nobody can help get it off. They take it off when I have my emissions inspection, but it comes back on two or three days later. Thanks in advance.
Check Engine Light was on and the engine ran very rough, particularly while idling. Repaired by Replacing the elbow-crankcase ventilation tube (Ford part number YL8Z-6767-AA) $9. However it took 2.5 shop labor hours to replace the part, which seemed a bit high.
