I'm sure you know what this post is.. I managed to shoot another spark plug free. Ripped the threads, so it looks like another $100 spent. Is there anyway to prevent the other 6 from doing so?

 

Make sure they are torqued properly

 

I'm going out on a limb and saying they're still all the factory plugs, but I'm not sure. How long are plugs normally good for?

 

Just replace them all! IF they are the factory plugs, it doesn't matter how many miles are on the truck, they ARE bad because you haven't replaced them and torqued them down properly.


26 ft/lbs. no anti seize

 

No anti seize? That's the first time I've ever heard that.. I thought lack of anti seize was the reason for them busting in the first place.. Instead of wiggling free all the way up, they wiggls until just a couple of threads are left and then they bust because there isn't much holding them down.

 

I did a lot of research on this and the consensus is to not use anti-seize. And the main reason they blow is because there were only 4 threads or so holding the plug in. On the first plug job I did on my truck, I used anti-seize without a problem. 5000 miles ago, I did the plugs again without anti-seize and I am having what feels like a misfire or some sort. (I started a thread about it) I now need to get in there and make sure all of the plugs are tight. Not saying this is the problem, but just thought I would mention it.

Can I ask what your truck acted like with the plug blew?

 

There was no warning if that's what you mean. After it blew it just smelled like gas, was louder than ****, and sounded kinda like a tractor.

 

When I did research on this a while back, everything I read suggested not to use anti-seize. I did my plugs about 20k ago. No Anti-seize. Just torqued them all down to 26ft/lbs. My truck is running fine and has shown no signs of a loose plug.

For reference, my truck did in fact have a loose plug before I swapped them. I did not realize it was loose either (even after checking, must have missed it) until I swapped them. It was the only plug that was hand tight, and my truck is whisper quiet after wards. I probably drove my truck for 10-15k miles with a loose plug and didn't even know it (my truck also made a ticking noise before hand which I wrote off as an exhaust leak since I didn't find any loose plugs). I am going to go and check my plugs again this weekend. Checked them about 10k ago and the were all still at 26ft/lbs

 

Yep, that's all there is to it. No big deal.

 

While replacing my intake manifold I was replacing the plugs and #3 was pretty much only finger tight. Looks like I got lucky.

Easy to replace and torque the spark plugs when you don't have an intake manifold.

Next time I will do the plugs myself.
