Sorry guys, I know this has been beat to death. But I consider it a success so I have to share it.

I prepared by reading the multiple posts on this and other forums. Ordered the plugs (a couple of months ago), got the socket extension and ordered a couple of cans of Kroil. I've used it on several projects around the garage but I'm a new believer in this stuff.

Prepared by blowing out the area around the plugs with my compressor. There was really a lot of dirt and debris that blew out. Sprayed about a 3-4 second blast of Kroil around each plug. Backed each one out about 1/8 to 1/4 turn. Talk about moment of truth! My knuckles were white. Each plug felt like a frozen bolt breaking off. I let that sit about an hour, turned each one back in and then back out about an additional 1/2 turn. Another hour and another 1/2 turn (between Indy 500 rain delays)! Started at 1pm, finished about 7:30pm.

The plugs came out surprisingly clean. The ones that did have carbon/crud were actually being further dissolved by the Kroil as it was still dissolving the junk on them.

BTW, I have 69,500 on the od. and do quite a bit of trailer towing so I was expecting some really bad plugs.

 

GOOD JOB!!! Give us all alittle hope Sad how a simple plug change has turned into an all day afair. I got just over 36,000 on my truck, wander if i should replace my plugs now. Did you do anything to the plugs before reinstalling?

 

Way to go! Nice to hear!

 

My plugs should come out nicely I better sell hah. Stealth, how are you affiliated with lifechurch?

 

We go there.

 

Cool. I replaced them in my mom's 5.4 3V Expedition yesterday with 33K on it. They all made a bunch of scary cracking and popping sounds, one I thought for sure was gonna break, but they all came out. I'm batting 1000 for these so far.

 

Yeah, sorry I forgot to add that I used the Nickel based anti-sieze compound, I put a thin coating on the ground electrode shield of each plug.

Here are a couple of pics of the old plugs (again, about 69,500 miles on them).


I really like this Aero Kroil stuff. What little carbon was left on the plug was literally melting off as it continued to be dissolved. I mentioned this stuff to my old father in law, he says he has been using it for years when working on his heavy equipment.

 

Good job on taking your plugs out without any problems it gives the rest of us hope on doing the job.
