FORD 5.4 L Aluminum Head Spark Plug Seat Repair-Quick-Easy

Our local motor rebuilder has had several modular block Fords in and thinks one of the major problems on the 3 valve motor is that the variable cam timing mechanisms can get all gummed up from either not changing oil or going to dealers for the super cheap oil changes with unknown oil quality. These new motors are very complex compared to the old small block Chevy or Ford.
