About 6months ago, cruising about 60mph; heard a "pop", lost engine power, engine light on, ...pulled over and discovered #3 cylinder missing the spark plug and the cop broken. Had it towed home (approx 25miles); went online and discovered it's a systemic problem with many other Ford V8-V10 1997-2003 motors.

Exhaust manifolds have developed holes in them. I believe Ford's suppliers provided inferior materials in their casting of the manifolds. This not only offers more pollution to the atmosphere but is a possible fire hazard. My vehicle has been well cared for and has only 37000 original miles. I have vehicles built in the 1950 and their exhaust manifolds continue to function. I believe a recall on these vehicles is in order and Ford Motor Company should make the necessary repairs at their expense. Updated 10/01/15

Was driving my vehicle and the spark plug was blown out of the engine. Could have caught on fire. Never heard of this happing before until the tow truck driver told me his Expedition with a tritonv8 did the same thing. Dealer wanted $700 to fix the spark plug and $1200 total to replace all coil packs and plugs which is ridiculous for a non-custom pick up truck. What if my wife would have been driving and not known what to do" it could have caught fire or caused a crash. The dealer rattled off the estimate like they do it all the time which tells me this is a defect in manufacturing and why has this not been recalled"

2002 F150 harley davidson edition with only 75,000 miles blew a spark plug out of the head. Ford admits no culpability even though they have tsb's. estimate to repair plug & change out other 7 spark plugs with 8 new coils was $2800. I could almost purchase a new engine for that. Found a reputable garage to do the work for around $900 total. Understand that I should get used to this happening until all 8 spark plug holes have been repaired. Ford man for 35 years.
