2005 V6 4.0 Blew up 5th cylinder (I think)
Well yesterday I was driving to our meet at Buffalo Wild wings and I was behind my friend. Well he acclerated so I did as well. Hit about 60 and then we stopped at the stoplight. I hear a ominous ticking sound coming from my truck so I got out and popped the hood. Couldn't figure out the noise so I plugged my tuner in. It said I had misfires on Cylinder 5. I came home and pulled the plug. It was smashed! the contacts were bent onto the electrode. I'll post pics in a bit. other than that i'm going to precision tune to have them boroscope and compression test the cylinder. (Fingers crossed) if the pistons shot i'm gonna do a rebuild with forged heads and everything. My truck only has 60k miles :(

You know the reason to upgrade to "forged heads and everything" would be solely to strengthen the motor right? You aren't actually gaining power. Unless you plan on a supercharger and a lot of boost, don't waste the money.

Why just replace one plug?
My '01 4.0 went to hell and back, drank water 3 or 4 times, I beat the living **** out of it for 100k and it was still runing like a top(minus the whole timing chain slapping issues the early SOHC's all had).
My opinion on your current predictiment: Ditch the old engine, don't bother fixing it, spend $800-1500 on a new to you, junkyard low mile engine. I got a 1,000 mile '06 4.0 for $1500. When you start looking at building one of these engines up, you're looking at 4,000 minimum for JUST parts. The 4.0L SOHC specific tools are also needed for those damn timing chain BS crap.

I've put about 1k on my 1k(now 2k) engine. Runnin' good and strong minus a little hickup under load(plugs or tune issues..possible TPS issue)

At this point I am so lost. I haven't swapped a new motor in but I put 3 new plugs on the drivers side in. All new motorcrafts instead of the E3 **** I had. Still need to replace the passenger side. So far so good. (500+ miles) the ticking is still there but its random and not NEARLY as loud. It can be very quiet. I'm so lost here. The guy at precision tune said my whole cylinder was messed up, but how could that be if I still have the same amount of power?
