02 E350 COP brass inserts advice
02 Ford E350 New to me. Had a bad miss on 2 cylinders. One 7mm retaining bolt was difficult, soaked over several hours. It turned way too easily once I got it going, however it extracted fully so probably OK. It had acted very tight but my tool was a small 1/4 drive ratchet.
2nd retaining bolt was not tight, concerning. As I got it out, found brass threads from the insert had torn and were on bolt shaft. After I sorted out the thread and pitch which is M5 x 8.0for all you future hunters sleuthing for that impossible to find piece of information, I ran a die on bolt thread and cleaned. Then I caught a bend in the bolt halfwsy up shank. How do you do that? Someone got in a big hurry with a large ratchet.
I will see how the insert cleans up with tap. But if I change intake, am I stuck with same 02 POS design or is the Dorman an improvement? What did Ford improve on 03 re-design?
Are they interchangeable?
Will anything help next time like anti seize?
Truck has maybe 100,000 miles.Don't trust odometer. Time to change all plugs and all coils?

You will hear people bad mouth the Dorman manifolds
I have used them with no problems several times
I think I would glue the coil down at least once
Or try to fix it like you are
Good luck

The plastic intake manifolds are quite prone to having the COP brass inserts dislodge and lose their ability to be retained properly. Sadly its due improper tightening or cross threading----for the most parts its an operator error. I don't know what others have done but this eBay seller has a possible solution if another isn't offered here: COP Inserts
There are tools used to reset these inserts by hand with a specially fitted 40 watt soldering iron, it seems these inserts are most commonly found in printed circuit boards or similar items. Here's a YouTube link that might be helpful for installation ideas as well as a source for parts and tools:
Do keep in mind I've never done this myself but I hope its helpful anyway. Let us know how this turns out if you try this method.
