If the vehicle is under warranty, cylinder head replacement is recommended. If the vehicle is out of warranty, Ford authorized the use of a specific thread insert to repair the head.

Started my vehicle today, 12/15/2012, at the mall and..boom!! then some smell of smoke inside the vehicle ...then more popping which sounded almost like a belt slapping against something under the hood. I had no prior indication of a problem except yesterday morning there was a vibration in the steering wheel while accelerating that stopped once letting off the gas. It did smooth out within 45-60 seconds and did not reoccur. Then today's issue occurred. I had the truck, F-250, 2003 Quad Cab, with 150-K miles towed to the Ford dealership about a mile away which was the place of original purchase. Initial estimate to repair it..$700.00; not a happy christmas gift

Loss of power when climbing hills. Problem is sparks plugs and coil packs will not tighten down for some reason they strip out on their own. Ford needs to perform the maintenance on these super duty trucks.
still not fixed lost #3 cylindr and #4 cylinder 2 times on each

It just "blew" out. Easy fix with the head repair tool. It's just a reamer and tap along with the insert from " Matco". I am not a mechanic but I did it myself in under an hour. 256,000 miles now and still going strong.

Happened twice, one at around 70,000 miles, again recently at 90,000.
Our technicians tell us the spark plugs in these engines can be very difficult to remove. Ford...
want to do myself but not sure exactly where the # 5 cylinder, spark plug and coil are located...
Replaced intake gaskets, no change. switched COP's and no change.
Just wondering how to change the spark plugs in this truck.
