I FOUND THE ANSWER!!! After days of searching for the answer, calling the local Ford store, all the mechanic friends that I have, the answer finally came to me. Go Old School. I called my machinest buddy, who has been machining for 30 years. He explained it to me.
The oil goes up into the hydraulic lifter, pressurizing it, making it hard. So, any mushy lifters are not getting oil or getting pressurized. From what he says, the lifters take a while for the pressure to bleed off once the pressure is inside the lifter.
So that is the answer, if you have a mushy lifter, it is no good OR
no oil pressure is getting to it.
The Ford dealerships response was replace them all - regardless. Which I have no problem doing, I just wanted to know good ones from bad ones.
Hope this thread helps someone out.
