F150 Engine Problems

Aluminium  grows a ton when hot and the cold head  holds its threads better  . On those ford's I have had much better luck cold plus you get a true torque on the new plug .one the 9/16  sparkplug models the best way to get them out is with a 3/8 impact gun.. sca red me on the first one but works great .

 

I changed the plugs in my '01 5.4 at 100,000 miles and after hearing all the horror stories was scared I was gonna cost myself a lot of time and money. The impact works great though and I had no issues.

If you guys ever smell raw fuel  on a Ford  look for loose spark plugs

I spazzed a little the first time I saw the guys pulling those plugs with an impact. Yikes. Works great though and we almost never break plugs.

One of th happiest days of my life was the day I took my f150 with 4.6 to the auction and told them to sell this piece of crap the best you can. I felt like Norm at Cheers whenever I took that thing to the mechanic.
