Im kind of new to this site, but have found it to be a wealth of info. I have a 02 f250 with the v10 with 120,000 miles on the original plugs. Im running a superchips programmer, afe intake and filter, and mbrp 4 in cat back exhaust. A few days ago I blew a plug on my way to work, its the 4th one back on the passanger side. I ordered the time sert kit and got that today. I have read alot but I have a few ?s I pulled the coil and plug tonight and the electrode end of the plug is smashed pretty bad and Im concerned that maybe the piston hit the plug. Also i want to check the torque on the other plugs and Im not sure what torque I should use. Also do most of you that have done this repair use a bore scope, i do not want to hit a valve or the piston. I also have a 2000 with the v10 and original plugs. It has 130,000 on it. Should I re torque the plugs and what setting should I use? It is running awesome and hate to mess with anything.

 

When I got my 2000 it had 142,000 on the original plugs and was running awesome. I replaced them and then it really ran awesome, plus the MPG went up about 1.5 MPG. So yes, just replace them and be done.

And welcome aboard!

 

I was thinking about replacing my plugs. What's a good plug to run in the V10?

 

Motorcraft plugs.

 

go OEM for plugs, if ur heads have more then 3 threads (which they should), then use 22-24lbs as a torque value.

i put mine in dry.

GL with the repair, after you get it sorted you should be good for another 50Kmiles.

 

So I did the time sert repair tonight, I built a platform that i could lay flat on my stomach on to do it. It went pretty smooth, I like the quality of the kit and it had really good instructions. I also bought an inspection camera and that helped a ton to make sure the valves were closed and the piston was down. It took me about 3 hours to do it, hopefully I wont have to do another one. When I first started it it ran a little rough but after a few minutes it smoothed right out. So far Im happy, I hope i dont have any problems with the insert, I need to get another 120,000 out of her.

With that many miles I would go ahead and change them. I only have 40,000 on my 2000 but I went ahead and changed the plugs and put anti seize on them just as a preventative measure.

 

15ftlbs is what Ford says, this guy says 30ftlbs and ive done my plugs three times in the 106k i have on my 5.4. Never had one issue and USE silver ant-seize!!

Going to change the plugs tomorrow. On a side note have any of you used the v10 y pipe that is sold on ebay? If so how is the quality and fit? I have a few broken exhaust manifold studs and I was thinking about doing the y pipe while I was at it. I also need to do my ball joints have been strongly thinking about doing the dyna trac bearing and hub conversion while its torn apart.
