Question about 2004 Ford F150

1 Answer

I have a 2004 F-50 with 5.4 Triton engine. This truck has 55,000 miles. I thought about changing the spark plugs before they get to 100,000 miles realizing at that time one or more are more likely to break off in the heads. Is this thinking ( changing now rather than later) realistic, or can they break off at anytime. I have a good mechanice who is afraid to work on the truck because of this issue. Is there anything we can do to facilitate getting the old plugs out in one piece. Is there anything Ford dealers are able to do about this serious design flaw. THANKS for any input. I have driven a Ford since I was 16, I am now 70, but this issue with the plugs is vexing enough to reconsider my loyalty

Hi, it is best you change them sooner rather than later as they will get brittle due to the heat, the thing is if its running ok and not missing then the chances are you may get another 50,000 from the plugs with no problem but if they do play up they will need changing and their is the problem.

if you really want them changing then the only advice i can give you is to make sure the spark plug socket is on perfectly strait and when you use a ratchet to undo them make sure it is held perfectly strait if its at an angle then they can break but holding it strait should get them out with no problems.

as for ford their is no easy option for getting them out if their going to break then their going to break, you need to make sure the tool is perfectly strait i mean their is no special tool you can use other than a spark plug socket. so as long as this is strait and not putting any pressure on it to one side they should come strait out.

1 tip i can give you is if you do it with the engine warm it should allow them to come out easier and when you put the new ones in make sure you dont over tighten them or cross thread them.
just drop the plug into the whole then using the spark plug socket turn them by hand they should go in a few turns before you need to get the ratchet on to tighten them up properly.

dont over tighten them once their in start the engine and make sure its not missing.

check the new plugs are the exact same length as the old ones and you should have no problems

as its only done 55th then the plugs should come out with no problems just take your time and keep the tools strait and dont put pressure to the one side when turning the ratchet keep it strait.

let me know if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks

Spark plug gap for 1997 mitsubishi trition 2.4 petrol ute

Spark plug gap does not effect the engine timing so it's not that critical. Thirty 5 (.035) should work just fine.
Otherwise consult a service manual fro your model or call a Mitsubishi service centre

2006 mitsubishi is using alot of fuel. Vehicles not pulling any codes. Thought about changing spark plugs but vehicle only 57000 miles. I would like a few suggestion other than changing out spark plugs.

Its a good idea to change plugs every 50K go ahead.
By looking at the plugs you can check engine's health.

With no codes...I'd suspect a fuel leak somewhere...

Hope this helps...

2000 4x4 XE 3.3 engine stalls out after reaching operating temperature, timing belt changed last fall and fuel pump changed. Vehicle will restart and may run for a while then problem returns. any ideas?

I have a 2000 nissan frontier crew cab. Great vehicle! about a year ago at around 100,000 miles she started stalling and running really rough. I replaced the distributor cap, all the spark plugs and wires...about $85.00 worth of stuff.
She now runs like a champ again. I would recommend this if you have not done it...I have owned the truck since it had about 55,000 miles on it. I had never done any of these things...the spark plugs literally fell apart when I pulled them. The last plug is a total is all the way at the back very close to the firewall. "You will SEE a small "notch" in the fire wall...this is where you follow the notch down to the plug with your will also need a 45degree elbow on the wrench with a long extender or you'll never get it off and the new one back was a pain!
Hope this helps. Aaron

I have a 2005 F150 5.4. It chugs and jerks into gears. I flushed trans and now it chugs and died in my driveway. I crank back up and it chugged while idle? Any thoughts

It sounds like it is possibly not the transmission at all. I would guess it to be either a fouled spark plug, which is quite common around 100k miles, or a coil that is bad. Check the coils first. If they coils test fine and the truck still chugs, take it to a shop to have them do the spark plugs. The spark plugs in this motor are not a job for an average mechanic. In that Triton motor, from my experience you will have a 50/50 chance of breaking the plugs off in the hole, and without proper tools, you will wish you had paid someone to do it. I've seen too many people learn this the hard way.

Spark plug gap

The correct gap is 0.054 Don't for get to buy the anti seize for the plug so it's easier to replace the next time your replace them and if you use Platinum Spark Plugs, your good for 100.000 miles before they need to be changed if your engine is running 100% on emissions. Good luck and hope this helps.
