I'm installing new sparkplugs here, what's the gap supposed to be? In the old days they put that info under the hood...

Anyone know?

 

For the stock plugs on the V-6 (4.2) the gap is 0.054

REMEMBER to use anti-seize on the plugs and dielectric lube on the boots.

 

Thanks Sport-

You should see these things I pulled out of the motor too.
Double plats after 110,000 miles might still spark, but yecch, they look like crap.
I just got this truck, I think the previous owner took the hundred thousand mile per set of plugs a tad too seriously.
Replaced the air filter with a KN unit (it looked like death warmed over too) and installed new plug wires.
Tomorrow it gets fresh fluids everywhere.

I have driven it since the change this evening and there is quite a difference. Gotta dig it when what you had and liked a lot gets even better with a little tuneup.

 

With out a doubt. Also maybe try chaing the fule filter if you havent all ready....

It goes in tomorrow as well.
Red Line is my choice for oils too.
The difference should be great all over, the truck will love it once I'm through.

 

Nothing like a man and his truck bonding together!

 

Motorcraft Double Plats after 110,000 miles -
At least I think these might have been the stock plugs.
Check out the erosion!


They are on my gallery.

I haven't figured out how to do a slick link to the gallery yet, so copy/paste for a view of some cool erosion on the double plats.

 

I measured .064 to .088 on these.
A couple of them had the central electrode melting down, a couple of them had the outside electrode eroding away.

 

Metal,are the numbers all the same on those old plugs?Looks like you have 3-DPs and 3-Reg.Platinums there.Which is typical of Ford to install from the factory to save money.Heck,those look good enuff to go another 100k miles! (j/k,of course)

 

Since you said your doing your fluids have you thought about doing a Power Steering Flush?

Mine has 33,000 miles and I took it in yersterday for a coolant flush and some other things including a power steering flush (all done as preventetive maintenance) and "what" a difference it made having the power steering flush.

To be honest the steering felt fine to me, no problems what so ever. I just wanted to do it as part of "my" schedule. I was amazed at how much better the steering felt after. You might want to think about it.

 

How much did it cost?

Thanks,
-Chris

 

Plugs:
They were 34eg and 34e
The parts counter set me up with six 34 eem plugs.
Hmmm...
Think it's time to look at the difference there.

Fluids:
The only fluid I've done so far is crankcase oil.

I've been thinking of having one of the oil change places do the brake system flush and fill, I'll probabally have them do the power steering too. Thanks for the heads up, Sport.

 

Power steering flush?I just took a turkey baster and pulled all the old p/s fluid out and replaced it with MerconV semi-synthetic AAMCO trans. fluid.How much did they charge you 01?

 

Metal,EG=double platinum E=regular platinum.The EEs are just what the factory calls for.Never heard of the "EEM". As far as the brake fluid flush you can do that yourself.Just get a friend to help.All you do is fill the reservoir with new fluid and keep bleeding at each wheel,about 4 times per wheel should do it.Just dont let the reservoir run dry.And start at the right rear,left rear,right front,left front.Good luck!

 

From what I have read and have been told what you did is a partical flush. A complete flush they turn the motor and disconnect one of the lines, as it is pumping out they are filling with new fluid so all the fluid in the lines etc gets flushed out.

I am "no" expert on flushing, well most flushing, but thats what I was told and have read about power steering flush as well as brake flush.

They (my Ford dealer) charged me like $39 I believe. I did mine with 33,000 miles on the truck and I dont even know if it is recommended until 60K +, not sure on that. Actually I read somewhere once that you don't need to flush it unless your changing out some parts, so please don't take my word on "it has to be flushed, or don't have to be flushed" I just did it for my own piece of mind and did not expect to feel any difference at all. I was extreamly surprised with the results.

Flushing the brakes works the same way I believe. Where you either have someone pumping the brakes, or some type of bleeded, and you keep bleeding until you see fresh fluid while keeping it full with new fluid with all four lines. I have never flushed my own brakes but am thinking about either doing it myself or having it done.

I won't do it myself until I post a thread on here and ask again for some advice from others here. This site has been one of the best things I have ever came across. Because of this site I did my own manual transmission fluid change as well as rear-end fluid change.
