Ejected Spark Pug

Lately I have had issues with first one then a second spark plug popping out. On the first, the shop needed to bore out the plug hole and insert a heli-coil. That worked well and $450.00 later we were on the road.

Now a second one have ejected. Is this a common problem with these engines? I have been around but never heard about this issue.

I was checking to see if this could be solved with JB Weld or do the heli-coil again.

Thanks for eventual feedback.

This is the first I’ve heard of that on the 3.0 Duratech. I don’t think JB Weld will hold up for that repair. A Helicoil is the best repair

Thanks for reply. JB Weld is a temporarily Hillbilly fix.

I got the tools, and inserted an heli coil. Engine runs fine, but I have an engine check light on that tells me that “cylinder 6 misfire on start up and bank 2 lean”. Cylinder 6 is the one that I fixed.

I installed a new spark plug, new coil pack. The hunt for the solution continues ... :?
