I have an 02 4.6L with 95K on it.

I'm looking to change the plugs tomorrow.

Are the 4.6L 2002 models susceptible to breaking in the socket or blowing out?

I wanted to replace with Motorcrafts but werent available where I bought them. Will be going with Platinum Autolites.

 

Should be no issue with the 4.6 for removal but I would only put in Motorcraft. Sometimes autolite is ok but some do not and they are a pain to change. Make sure you use alot of dielectric grease.

 

motorcraft plugs are the only 100% guarunteed plug to work properly for the modular engines. and as already said use lots of dielectric grease. and just be patient or else something will happen. my friend stripped the threads on his trucks 5.4 even with the heli-coil because he was in a hurry.

 

I thought the old body style had the blow-out problem? If so... I don't know if I'd want to use a lot of dielectric.

 

Iput in new BOCSH plugs in my 4.6 about 3 weeks ago and I just took a trip to California from colorado and I have had no problems what so ever

 

big mistake

Im gonna see if I can return the Autolites and get the Motorcrafts...I want to do this once and once only.

 

Dielectric doesn't go on the threads - it goes in the boots. It's antiseize you may not want to use, slap them in dry.

 

For cryin out loud already!!



Almost dumped my bucket of coffee on this laptop when I started reading this one..

 

I've seen that pic before it doesnt scare me and maybe you just got a bad plug. IT happens every now and then

 

Easy Jbrew! He may have found a new use for the dielectric!

 

Make sure you post a pic when it does

 

Yea, somebody just got confused..



It happens, glc was on that one already. I was yucking it up while I was scrolling down to see who caught that

On the other hand, dielectric will solidify after awhile - It just might throw a Kung-Fu grip on those plugs...? - Well, fir a little while anyway

 

I've returned the Autolites and have ordered Motorcrafts...Guy who's gonna do em for me says the job is normally 3-4 hrs, but he has it down in 2.

 

Dealership gets yuh for 2.9 hrs on average - (Dual valve COP'ed Modulars)
