My friend has a 99 F-250 with the V10 and I would like to know if anyone has instructions (special tools, weird tricks, torque specs for plugs and oil drain plug, drain plug gasket?) for spark plug and oil change. Mostly I am interested in the required torque specs for the plugs and the oil drain plug.

The engine is slightly misfiring and I'm going to take a look at the plugs tonight (hopefully they're all still in the engine ) and soon I plan on changing:

Plugs
Wires (if it has them)
Fuel filter
Air filter
PCV
Fuel injector cleaner

Thanks for any input that you can provide, if you have any other recommendations I would appreciate hearing them as well.

You want the plugs snug,but not overtight.Unfortunately there have been some plug blowout issues on the 99 and 00 V10s.Aluminum isn't very forgiving when it comes to overtightening.I don't have the actual plug torque spec.

 

You know, I have heard and read a bunch of horror stories about the '99 v-10s blowing plugs, I think I even heard one guy say his chunked one through the hood. I guess I must be in the minority or something, because I have a little over 125,000 on my '99 F350 v-10, and I have not had one single problem with the plugs. I have changed them once, and am changing them again tomorrow. What is the story with the plug blowout thing? Is it just a sporadic problem, or is it occurring pretty much as a regular thing? I drive my truck pretty hard sometimes, and havent had any problems yet.
