I'll try to keep this short and simple because it's been an odyssey with this truck the last 2 years. It spit out the #2 plug. I initially used a helicoil insert kit for a repair along with a new plug. Everything was working great for about 2 months. The #2 cylinder started misfiring so I pulled the plug to check if it was bad.

Here's where I messed up. When I initially installed the repair kit, I did in my driveway because I didn't want to drive it until it was fixed. I dipped the drill bit and tap in grease to catch the shavings. Then I installed the insert with red Loctite. Except, I didn't clean the grease off the threads. The Loctite never "glued" to anything because of the grease. When I pulled the spark plug out, the insert came with it. So, I grabbed a new spark plug (the old one was shot), added Loctite, and started installing. I must have lost count of the turns because I tightened it down until it pushed the socket off the plug.

I can get the old insert out if I can figure out a way to get the plug out. I tried grinding down a plug socket, but that didn't work. I have a CalVan insert ready to go in behind the helicoil.

If I use a hole saw to remove enough metal to get a socket on the plug, will that cause issues with the new insert? Or does anyone have a better idea?

Thanks in advance!

 

A question - During your failed install (too deep) how much force was being used?
Have you made any further progress?

 

DirtCity,

It’s been a few days since you last posted. Have you resolved this issue and if so, please post the solution? Feedback is important so that we all learn solution paths to these issues.

Thanks in advance

What a mess . No info on engine size etc . Seems like the head should come off . Never use a heli coil on plugs . A helicoil is not an insert . I would favor a timesert but you have to have access to the tools. I have heard that machine shops use timeserts when they fix heads .
Some carb cleaner would have cleaned that grease out of there . . The grease was a good idea for removing shavings
Depending on other conditions of engine I would consider a reman engine installed myself .

 

Sorry it’s taken me so long to get back to this. The last 2 weeks have been crazy for me, so I forgot I had even posted this.

If you cannot offer help without my entire g*ddamn biography, you don’t know enough to have a valid answer. For example, this is the 11th Gen forum. 11th Gen’s only had 3 available engine options per year. Only 1 of those options had an issue spitting plugs. If you actually knew what you were talking about, you’d have been able to deduce which engine I was asking about. I have zero desire to feed your parasitic longing to invade everyone’s privacy. Go be a pervert somewhere else.

I did solve the problem. I got a hole saw and slowly removed metal around the plug until I could get the socket to catch the shoulders of the plug. It was late yesterday evening when I got the plug out so instead of spending more time trying to remove the old insert, I installed a new plug and took it for a test drive. I still got a code for a misfire on that cylinder, so it appears my main issue is something else.

 

whoa, that escalated quickly.

 

Seeing that you solved your problem, and you want to be rude to other members this thread is getting closed.
You can make a new post about the different problem, but I would suggest you don't insult other members.
