Navigator Tune up any ford guys out there?

Supposed to do a tune up on a 2001 Navigator with the 32v 5.4 in it, and got a quick question. Are the plugs and coil packs under what looks like a cover on top of the valve cover? Mitchel absolutely sucks I hate that program all it says is remove and reinstall plugs no pictures, and says charge 3hrs of labor. I need to know how in depth this is so I can give my buddy a price for this side job, and to know If i have enough time to dive into it tonight. thanks a ton Sean

it's been a while, but i belive youre correct. i had a coil go bad in mine, i looked under the hood and only found 3 of what i thought were the plugs, took it to the dealer they said that was where they were and some are under the cab that hangs over the motor and you need a "special tool" to get to the back ones. Probably dealer talk for "we're gonna charge an arm & leg". but yes they are hidden good.

the cover i see looks like a long oval that has a few nuts holding that on top of the valve cover. I figured the back two would be barried under the dash like the f-250's we have in the fleet, but there not the the fancy 3 valve crap, and like I said Mitchel on Demand really is a waste of money and time trying to find any thing in it.

don't even buy the tool to change the 3 valve motor plugs.you will regret it.the plugs have a pertruions that build up carbon so when you take'em out they brake.TSB on it.

Yep, not worth the chance. My son's been there, done that at his old shop. Send it to the dealer or someplace with really good insurance on ruined heads/engines.

To get those 5.4 3V plugs out, you loosen them off untill they seem to get tight, and then soak them down with combustion chamber cleaner, and walk away for a while. Works very well, and I havent broken any for a while. Also, torque the plugs to Ford spec, as there is also a TSB for the plugs blowing out of the heads if not properly torqued.

i did the tune up last night, they were not bad to get to all once the covers were off and with the right combination of extensions. Had not problems with them coming out or going in, it was missing and the MIL was on, all seems to be ok today tho, thanks for all the replies tho!

Sounds like you did okay, if the plugs came out and went back in with no problem. The aluminum heads and relatively short number of threads take some finesse to do the job right. On the Mustang forum they recommend setting the torque wrench to 25 ft lbs and never using more than that torque to remove a plug. They just keep soaking it with combustion cleaner until 25 ft lbs will break the plug free.

Another common failure/weakness is the coil on plug. Cracked rubber is a good indicator, but does not always cause failure. When they changed plugs on my 2000 Expedition I had them change all the coils with cracked insulation (3 out of 8) and each COP cost about $30-35. It was a fairly expensive tune-up.

Ford also has a TSB to check the COP on the right rear cylinder, because a leaking heater hose connection may leak directly on top of the COP and cause it to fail.

Doing a tuneup on a Ford 5.4 two valve engine is not for the faint hearted. Besides often being stuck in the head with carbon, there have been many of these engines that have spit the plug out of the head, also messing up the threads - which means you have to spend a bunch to buy a kit or $1500 at your local Ford dealer for him to fix the head.

I'm glad to hear that you were successful. ( I can hardly wait to do my V10, 6.8 )

we do the 2 valve 5.4 all the time here on our fleet, only had I think one, *knock on wood* that we had a problem with where we had to fix the threads, of course it was the farthest one back but hey, it happens. Had some were the intake cracks and coolant kills a coil or two. We always go ahead and replace the coil boots and clean the secondary and primary contacts on the coil packs. Some one told us, either a ford Tech or our Jasper rep that when removing plugs in those heads do it when there like 70 degrees, not cold and not hot and you should have minimal if any problems.

The biggest thing with these is to take your time, and don't rush. If a plug is coming out hard, work at it, and don't force them. If you do, they will break and cause a world of grief. Rotunda just sent us a "new and improved" tool for removing the protrusion that remains in the head when the plug breaks. Have yet to use it, but I will in the near future, iI suspect.

The slightly warm comment was right on the money, it helps a lot.
