Tick in engine at idle due to manufacturing defect effects behavior of driver and strangers toward operator hearing, resale value greatly effected. Poor lubrication to #1 valve train. TSB 12-1-17 describes a fix that causes greater harm by starving exhaust cam journals of oil by using oil plugs to block oil flow thru hydraulic cam to the exhaust cam valve journals on cylinder 3 and 4. Efforts to secure remedy or reasonable information to effect repairs from Ford result in misleading directives, over charges and denied access to upper management to secure reasonable discussion and or meaningful remedy. Noise is always present at idle after warmed up. Loud offensive irritating. Contacted several Ford dealers and Ford customer service. Ford refuses to give access to upper management for resolution.
