Going on a week to replace spark plugs on my Escape.
Can someone with a 3.0 Duratec please tell me how many turns you get when threading in the spark plugs?
I went to replace plugs & realized they only threaded in approximately 5 turns = 1/2 available threads on the spark plug.
That didn't seem like they would be in all of the way so I counted the turns in hand & it would be about 10 turns to completely thread in.
I then looked at the old Motorcraft plugs & can tell by the debris packed into the top 1/2 of the threads that these were installed only 1/2 way.

After searching "on-the line" I sprayed a little PB Blaster into each heads plug holes on 2 days & let it sit for a day after each spray. Then, ran a Spark Plug Thread Chaser tool to clean carbon out of each heads plug threads. The chaser easily threaded in 10 full turns. No ratchet necessary - turned the extension in my fingers. Then tried the new spark plug again. No Joy... Only threads in the same 5 turns... Approximately 1/2 the plug threads.

It's difficult to tell if the plug is seated all of the way in or not. Maybe this is how it's supposed to be - hence my question to confirm.
AND
All 6 plugs seem to thread in the same...AND if they are not fully seated they appear to be close.

This is either... the way it's supposed to be - plugs thread in 5 turns - 1/2 the available threads...
OR
Maybe the previous owner had to use a thread repair kit. Which may become more apparent in a week when my newly ordered Borescope Tool comes in.
I know my request to count a plug turns is a PITA so I would like to thank the brave & bold who graciously count their plug turns in advance...
I really would like to know if "all's good" or if I have other tentative issues to address.
Thanks Again
Don
