 Subject: Broken Spark Plugs
IP: Logged
Message:
So my truck started running like crap and codes 302 and 305 popped up and I removed the spark plugs just to find that the tip is broken. I'm guessing a cylinder would have to have hit it in order to break the plug. Dont even know how one could have happened but 2? How screwed am I? Here's a pic.

Did you examine the plug close. Not likely the piston hit it. my guess is it burned off. How old are the plugs
I doubt the piston hit the plug. More likely it was defective and broke off over time or it was burned off for some reason. Do a compression check on the cylinder and you'll have your answer.

Kinda looks like excessive heat in the combustion chamber. Has the engine overheated or ran hotter tha normal?

Plugs had probably 7k mi on them. Trucks been running around 190-200 so not too hot. It's just weird to me that 2 of my plugs did the same thing. I replaced them and it still doesn't run right but I'm gonna check my wires again to make sure they're correct.

Looks like some detonation going on. It's not simply broke off, which could happen if you installed the wrong plugs (reach is too long.) The metal that is fused on to the remaining part of the electrode is what makes me think that.
If it is a cylinder that you can easily look into the spark plug hole try bringing the cylinder near TDC and shine a light into the hole. I suspect that you have a crater in the center of the piston or maybe even a hole. If not you are lucky. If the material is magnetic you might try fishing any remaining material out with a magnet. It's also possible that the material was blown out the exhaust valve.
Right now you are faced with two choices. One, you can choose to do nothing and hope for the best. However, you may want to expect the worst. Two, you can pull the head(s) now and see what the damages are. This will cost some money and down time but it may also save you money in the long run by not inviting any more damage.
At the very least do what OBIO3 suggested and do a compression check.
