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 :(

Weird. That sucks though, I wonder if the plug just got hot and grenaded. Even then, if there are pieces of ceramic from the plug down in your cylinder then your cyl walls may be scored up pretty bad.
Good luck with it.

lol Forged heads?

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.

I was gonna buy Zabeards supercharger. And yes I put a new plug in and the clicking persists. Also the old plug got hit by something. I don't know what. it came out in 1 piece tho. And I'll let you know what comes up on the boroscope tomorrow.

If the motor is toast then I wouldn't even bother to rebuild it for power. Just do a 5.0 swap.

Yeah but a 5.0 swap is going to cost alot and involve alot of skill I don't have. I'm not even sure I can do the headwork on my truck yet (If it needs it)

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.

Well only one of the plugs was bad. They were new 2000 miles ago. And also, How much time and bsing did it take to put the new engine in?

IDK....had the old one out in a few hours. Threw the new one in and put it almost all back together in 12 hours. Biggest headache was wiring on my end....I should've just used my old harness...but I was stubburn on trying to use the '06 harness in my '01. I had about 12hrs of disassembling and re-wiring to deal with to fix my stubburness. Had I used my '01 harness, I wouldn't have had ANY issues with the swap what so ever.

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)

If I can fix it for about 400 to 500 bucks I will. But if Its more I'm contemplating on doing a motor swap. Since I don't have pats it should be easier. But UGH! I'm mad, I want my truck fixed.

I was wondering why you didn't make it to the B'Dubs meet. I don't think anyone really stuck around for a long time anwyay, but yeah.

Sucks to hear but should be fun swapping the new motor in. Good luck.

You know, did you change the spark plugs or a shop? Anyone think the spark plug could have been over torqued, which could possibly cause the piston to crash into the spark plug??

Not gonna happen, there is more than a few thousands clearance between the plug and piston, so basically, it would strip the head out before you could tighten it enough to make it hit the piston.

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?

Did you have a bore scope put in the cylinder? I'd do that before doing anything, might save yourself some time.
