Scared

Hey guys I have a 2006 xlt with 5.4. I read about allot of problems with the spark plugs breaking when being removed! I have 75000k on it. I picked it up used. Should I be worried about this? Is it happening to allot of trucks or just a few here and there?

Hi there, well with your truck now having 75000k on it, I would be pulling the plugs out of it and installing a new set.
By doing this every 60,000k's, as well as using the special Ford lube on the plug threads, you should be good to go. Better for max. performance and fuel econ. as well.

The longer you leave them in, the greater the odd's are that the plugs won't come out cleanly. I would also recommend that you have a Ford Motorvac (engine decarbonization) done before removeing your plugs, with an oil change to follow.

When changing the plugs a couple things I have picked up.
Blow all the crap out of the holes.
Shoot some WD40 or similar down the holes.
Crack the plugs about a 1/4 turn and shoot down some more WD40 and blow out again.
Put some antisieze or similar on the plugs when reinstalling.
Torque to correct specs. My 99 was something like 14 lbs.

good tips, cracking them a bit and spraying some penetrant seems to work for most people then let it sit, turn again, if it creeks stop! spray some more penetrant! Mine were creaking with only 40k when I changed them!


Edit: has anyone tried Seafoam before a change? maybe it would break up some of that carbon buildup in there? Something to think about...

On my '05.
I took it into Ford and had them do it.
It was under warranty. I asked ahead of time.
If the plug breaks off who covers it?

They said because I was under warranty they would cover it.

Done. $200 later!
good to go.
