Spark Plug Problem
I have heard that 97-03 5.4L Triton engines have many problems with the spark plugs either blowing out, or breaking inside of the hole. What is a solution or a way to prevent this problem from happening? If i can get the plugs out i am going to replace the plugs with platinum plugs so they don't rust in place. Is this a viable solution or is there another known way of fixing this issue?

pretty sure thats the 04 & up 5.4. I just did mine with no issue.
|
Okay hopefully mine goes smoothly then. I really dont want to have to do any work to the heads
|
yea the problem is with the 04-07s. Ford installed 2 piece spark plugs that were prone to breaking off inside the head. the 97-03s do not have this problem.

the 97-03 4.6 engine has the spark plug problem in that model year

on the 97 to 2003 f150s with the 4.6 liter engines the spark plugs are only held in by 2-3 threads and if not torqued down just right it will shoot the plugs out of the heads

Do a quick google or forum search for "spark plug blow out" and if this is your only mode of transportation, get the Timesert kit before you start.
|
with the timesert kit you wont have to take the heads off if you strip the threads, if you are careful you shouldnt strip any of the threads
