After getting a misfire code on number 4 and 8 I thought it was just a coil. I drove it another mile home and pulled #4 and after removing the bolt the coil and plug all came out together. #8 looked fine, but as you can see #4 is FUBAR.
I tried screwing in another plug and threads in the head are gone.
My truck is 1999 with 220K on it. I change oil, filters, fluids on schedule. I heard a slight ticking about a week before this happened and did a quick scan under the hood, but didn't notice anything. #4 is behind the air box, so maybe if I pulled that I would have seen/heard an exhaust leak.
So has anyone else had this happen??? My questions.
1. Why? I didn't install the plugs, maybe they weren't tight which caused the leak? The bolt on the coil was tight.
2. Anybody ever rethread?
3. So time for new heads or a new 4.7?
Hope everyone is having a better Sunday than me.
