Don't think I will just put in the insert.without pulling the head...something about metal filings down the Big hole sort a "screes" me! What a bitch to happen just because some "pimpley face don't know their azz from a hole in the ground" 2 bit helper didn't or wasn't told to use a dab of anti-seize! this shat would get your azz fired if you worked for me.....Marty.

OK here's the deal, turn the plug back in the hole untill it releases a bit, look for a product called n-force by BG products, (Automotive Shop) this is a foamming releasing agent... I've had really good luck with it on the 5.4 DOHC Fords that tend to snap the plug off in the head..

Whut I wuz told.
OK, don't bother getting the flame throwers out, I am only repeating what I have been told (read) here on the forum.
1: No anti seize on the spark plugs. They need to be well grounded to work well. This one didn't make sense as the plug will ground via the seat, but that's what was written.
2: Do not put a cold plug in a hot head. The head has expanded from heat and the cold plug could mess the threads up. This one makes sense and could be what happened if the dealer did that.
Just passing it along.

I have seen it done a few times over the years. I agree take it to a good machine shop that will use the best parts. When I have seen it done with the head on the bike yes they vacuumed the cylinder. I do not think it was their first rodeo. I watched a guy put one in my my dads bike in 1979. Is still runs with the same helicoil in the head.

This one comes from careless people getting anti-seize on the base of the plug (at the top of the threads), and even on the electrodes. If you put the anti-seize where it belongs, i.e., only on the threads, you'll never have a problem. I've been using copper anti-seize on plugs for decades.
