The 5.4 liter engine has a knock that
Ford ford calls a cold engine knock.
Funny it knocks when you pull off of
the interstate after driveing 180
miles. I would hate to see what they
call a warm engine.
The problem will keep me from buying
another Ford. There is an obvious
problem with the 5.4 engine that they
are not willing to admit. I would say
it was liftr rattle if it had lifters.
