I have a 99 F150 with 190,000 miles and my wifes 2000 expedition with 150,000 miles. Both have the 4.6 but one is a ceveland and one is a winsor. Never had a wrench on either one.
I thought Cleveland and Windsor described 351 engines of yesteryear.

Also, check the door frames kinda where your elbow would ride with the window down. The power windows like to over torque the frame when closing, causing cracks.

I believe the 4.6's(I cant remember if it was the 4.6 or 5.4) two piece spark plug design had a problem with the electrode part of the plug getting stuck in the head while the insulator gets pulled out cleanly. This can be changed by getting a one piece spark plug.
Two piece spark plug?
Just don't use anti seize on the "one piece" spark plugs during installation.

I thought the 4.6 were described as romeo and windsor motors.
Yep your right. A few years ago i use to go on a f150 forum and they had a section where you could look at your door vin and tell what all the numbers and letters meant. I knew that my wife`s motor was different than mine, and as i posted cleveland came to mind. Growing up in the 70`s i guess i was thinking about the 351s.
But the big talk about the plugs over there were on the 5.4s. They seem to blow right out of the head quite often, the 4.6 it seemed rarely if ever.
