Just getting ready to do this on my father's Navigator, saved me a lot of time! Thanks!

@rwdplz1 Glad the video help.

you shouldn't add never seize or anything to your new plugs, sometimes it will keep them from grounding to the block and wont produce spark.

@robduggins7 really what makes you say that? I have never had a problem using never seize. now if your one of those people that use a crap load sure you will probably have a problem. but if you only use a very little bit as in a pea size amount you will never have a problem. And the next time you change plugs it make easier to get out. beside i have been working on cars, trucks ect... since 1984. and when your dealing with aluminium heads you better use something because they strip out easy.

I have a Lightning ... time to change the plugs. Should I spray them with carb cleaner or anything to loosen the plugs BEFORE attempting to remove them? I heard stripping the plugs is a very real possibility for the novice such as myself.

@nswartzentruber It would be easier to let the motor run for a few minutes then turn it off let it sit this will expan the heads making it easier to remove the plugs. If you want you can use WD40 its better for the thread taps on the head than PB blaster which will eat through and or weaken the threads. In my case I did not use anything I just took my time taking them out. Your hardest plugs to remove will be #4, 7, 8. Just take your time and go slowly when turning the spark plug.

@Marko3123, The PCV tube comes out of the drivers side valve cover and then into a PCV heater prior to going back into the intake.

@robduggins7 , using a little anti seize on spark plugs, especially with aluminum heads has been a common practice by master mechanics for decades.  stop providing bad info.

Umm where the hell is the PCV valve on the 99 5.4??

Excellent vid. Saved my day!

@U8nothing Thank you, we didn't use anything to "loosen" the plugs ... sadly since I don't have a garage I got all plugs except 7 and 8 (two on drivers side in the back) because it got dark on us. I didn't remove the fuel rails for the 6 I did change, however looks like I'll need to take the left rail off along with the power steering fluid bracket and some hoses to make it easier. Thank you sir!
