I'm working on a 99 navigator. It blew a plug out so I bought this atd5410 kit. Seems like this kit isn't right. The drill bit doesn't reach far enough in to remove any aluminum and the tap won't reach far enough 8 to tap anything. Iv moved the clips like the directions said and it's still not enough. Anyone know if I got the wrong kit or something?

That link says it's for 04-08 engines.. Maybe it's the wrong tool?. -

I used this cheep'o kit
with this style insert
installed 2 over 80k miles ago without a problem. Now I'm not sure if those 2 kits I posted were the correct size but is the style I used very successfully.Comment

Anyone else care to add on which style kits to use? Cars dead until I get the right kit so I really dont want to get the wrong kit again.Comment

Done a bunch with that style kit. hope it isn't a rear cylinder,they are a bitch.Comment

Rear cylinders look like they would be hell. I had to do #1 and #5 on my Expedition and it was pretty easy. I used the cheap Auto Zone kit.Comment

He's had 1 blow out on the road in NM and now one blew out in town. I told him I would just do the other 7. The shop that repaired the one in NM charged him for 2 spark plugs repaired but only fixed one. They did replace both coils so it looked like they fixed both cylinders. Im trying to get the name of the shop so I can send them borescope pics of it.Originally posted by JimD View PostComment

Fuck doing all the others if it's not needed. Isn't the main reason this happens on n/a engine is because they are coming loose?Originally posted by stephen4785 View PostComment

Don't know a about loose, maybe b/c its only got 4-5 threads. People i work for can barely scrape enough to do the 1 let alone rest of them. But thats great if he's got the dough to do it.Comment

I took 4 plugs out that were barely hanging in. They had carbon all over the plugs. The stock heads for 5.4's only have 3-4 threads to hold the plugs in. Once it's ran with loose plugs it widens the threads. It's my cousins car so I'm going to all of them.Originally posted by snacksnack View PostComment

I believe the later 5.4s got more threads than the early (02-04??) Engines.Comment
