Changed my spark plugs today

Having read many threads regarding the dreaded Ford blown/stripped spark plug issue, I decided I had better do it soon or don't do it at all. 2002 F-53 chassis for my Winnebago Adventurer, 80,000 miles. Bought it at 35,000 miles in 2008 and I don't know if the PO ever had them changed. I doubt it as the recommended change interval is 100,000 miles.

I was expecting to have troubles changing out the plugs, so I did these steps:
1. Removed all ten coil/boots. A 7 mm socket is needed for the hold down screw. I used my Milwaukee 18 volt impact driver and a long extension to speed the process.
2. Blew out the plug hole with compressed air. I improvised a long nozzle with some left over 3/8" hard brake line. I then vacuumed the area around the hole and blew them out a second time.
3. I used the same piece of brake line to squirt PB Blaster into each hole and let it sit for about 2 hours.
4. Using a 5/8" plug socket, two 6" 3/8" extensions and a flex joint I just tweaked it with the impact driver just to rattle the threads to encourage the PB Blaster to really soak in.

Turns out that was as far as I needed to go as 8 out of 10 plugs came out without any more than one second of rattling. The other two took only modest pressure on a 3/8" ratchet to loosen the plugs. Those plugs were way too loose in my opinion, lucky they didn't loosen and blow out. Looks like I caught them just in time as one plug looks like it was getting some blow-by.

Access through the doghouse was much easier than expected, I did loosen the air intake to reach two of the plugs, but even that might not have been necessary.

I replaced them with the same platinum Ford Motorcraft plugs that I took out (AGSF 22WM also labeled SP-479), I was expecting the three piece plugs from hell, but they looked like regular plugs. At just $3.59 each, I was a happy camper. Out of the box they were within two thousandth of the recommended 0.054 inch gap. Old plugs measured 0.064 inches and looked to actually be in pretty good condition.

Factory specs call for torquing them to 11 ft-lbs, but I went with the recommendation from blownoutsparkplug.com and bumped it up to 28 ft-lbs. Partly because they were so loose when removed and partly because the blown plug guys said ten certified Ford mechanics are using 28 ft-lbs and they have bench tested the plugs on an aluminum head at 100 ft-lbs without stripping.

Fired it up and all is good. I hope this helps any of you that are considering a DIY spark plug project on your old F-53 2 valve engine.

Having had issues changing plugs on the Chrysler 4.7l and 3.7l engines with stick coils , I'll add ; clean the stick coil " O " rings and apply a light coating of silicone base grease, to the O rings, before installing , the next person that changes the plugs will thank you.

Good write up. Have you ever wonder why the ford engineers say 11 foot pounds and ten certified Ford mechanics who i presume were trained to meet ford standards say 28 foot pounds.

Stay tuned, if I can stay on track, I plan on clear coating Wanda, gelcoat, graphics and paint. We'll see. And I need to pull up half of my Allure Ultra floor to close up end and longitudinal gaps. Does it ever end?

Just a note that the Ford factory plugs have a dab of paint on the top terminal where the coil or wire plugs on.

Paint = original
No paint = they have been changed

I also apply a little dielectric grease in the spark plug boot to ease in removal of the coil/plug wire next time.

Did you put any lube on the threads of the new plugs or did you install them dry?

Only lube was whatever PB Blaster was left on the threads. Don't expect to ever have to remove them again. I presume they were installed dry at the factory and that seemed to work well.

Great write up. I want to do our camper but have a trip planned to Charlotte this month so waiting until I return. I also have heard folks say to change the boots while doing this. I have plugs and boots sitting ready.

The breaking plugs are a 2004 and newer issue.

Stripped threads were the early 2 valve heads.

I replaced my plugs last year used the same procedure and 28 ft-lb of torque. If you use the plated plugs no need to lube the threads. If you lube the threads, need to torque at a lower value.

The 9/16 motorcraft plugs are the ones that are two piece and leave the porcelain in the hole, if anyone changes theses I recommend going back with a champion plug they make a one piece replacement
