Thanks Drae. Added temp sensor to the list. Great ideas for marking and remembering where things go.

Before I spent that kind of $$$, I would check/replace any/all rotted vacuum hose, hose assemblies, PCV & hose & elbows that look rotted or feel spongy. Does not cost near the gasket replacement but will need to be performed especially if nothing has been done during that 154k miles. I replaced most of mine for under $200 and a little grime on my hands (use Nitrile gloves). Go to www.rockauto.com
I do not know the current discount code but someone else may chime in. There is a vacuum assy behind the battery also. Heat and age are terrible on these vacuum lines/hoses.

Rockauto code valid until end of year I believe.

Getting ready to start this job today. Thankfully the garage has warmed up to a toasty 42 degrees. LOL.
Based on forum posts, it doesn’t seem super common for injectors to fail, but it does happen.
Nobody’s mentioned it yet, so I thought I’d ask. Should I replace the injectors while I’m there? Overkill?

The injectors should be fine. If anything, I'd just run some injector cleaner through the fuel tank once in a while. Remember to lube the injector O-rings before re-assembly, so they slide back in their homes without binding up or tearing. Close the garage door and put one of those portable heaters in there !

Started on this project today. It's going pretty well except for one of the nipples broke off the EGR pressure feedback sensor while removing the hose. The plastic is brittle and crumbles easily. Ordered new Motorcraft sensor. However, more importantly... I cannot remove the coil from cylinder #2. I believe the brass nutsert is spinning in the plastic of the manifold. The bolt turns, but will not loosen. It also has that bumpy feel as it turns. All others were removed with no issues.
Anyone have any suggestions as to how to get the coil bolt out?
Since it's the only one, maybe just remove the manifold with the COP in place?
Thanks

Looking online for a Motorcraft manifold. So far can't find one. Tried Amazon, Ford Parts Giant, Rock Auto.

You might not like to find one lol…
I looked at only a couple of random Ford OEM places and they were similar. Maybe others know better places.
PS. Don’t tell anyone but I used a Dorman several years ago and it’s still ok. This is not an endorsement!

I found a new Motorcraft manifold at a local dealer! $255.01 out the door! So thankful!
Inspecting with my novice eyes, the seals appear to be intact. No obvious signs of leaking. Hoping the plugs look normal when I take them out tomorrow.
So far it's not too difficult. It's meticulous, but it's doable. Take your time, be present.
Here's a few photos for interest. Anything look out of the ordinary? Any signs the valve cover gaskets are leaking?

That is really great news! I have no idea why these prices should be so different. Did the Motorcraft manifold come with the big insulating “box” under it?
