We all started talking in another thread about spark plugs in our Ford V-10 and I found this valuable information that I felt was worthwhile to post for others.
The writer is an auto mechanic expert and he says you should actually reduce problems with spark plugs getting broken or stuck if you wait until the 100,000 miles mark by replacement earlier by a trained mechanic at about 40,000 miles. This will reduce a possibility of a stuck or broken spark plug..... Sounds like a good idea for me with 36,000 miles on my Ford V-10.

View Out for Ford Motorcraft Two-piece Spark Plugs That Break!

The Motorcraft PZT 2FE Platinum spark plugs have a crimped lower electrode shell that gets coated with carbon, triggering it to stick during the cylinder head. Rust and corrosion to the decrease plug shell can also cause it to stick. Any time you try to unscrew the plug, the lower shell breaks off and stays inside the head. Eliminating the broken shell involves a exclusive Ford, Snap-On or Lisle extractor tool. Worse however, if any shell or electrode fragments fall to the cylinder and cannot be fished out, you could need to remove the cylinder head to get the debris out.
A lot of professionals encourage replacing the original equipment Motorcraft spark plugs just before the get as well numerous miles on them (above 40,000 miles).
Replacing the plugs at lower mileage will reduce the danger of them sticking and breaking. Waiting till the authentic equipment spark plugs have 100,000 miles on them is asking for difficulty!
In case your car features a lots of miles on it (say more than 80,000), as well as spark plugs have under no circumstances been replaced, it could possibly be best to just leave them alone. The authentic equipment Motorcraft spark plugs possess a platinum tipped center electrode. The plugs should last upwards of 100,000 miles or more. Lots of plugs will actually go up to 140,000 miles or more with no problems – furnished the engine is not really burning oil and sees enough highway driving to help keep the plugs clean (frequent brief trip stop-and-go driving could cause plugs to foul). So as long as your engine is commencing and operating fine, and having typical fuel economy (no misfiring and no Examine Engine light with misfire codes), there exists definitely no have to change the spark plugs.
Here’s an additional believed. Should you be organizing on promoting or trading your Ford truck or Mustang in the subsequent number of many years (and it can be operating fine now), leave the spark plugs alone and let the next owner be concerned about shifting them. The threat is in the event you attempt to alter large mileage plugs and break off several plugs (which frequently occurs), these spark plugs could price you lots of revenue. Several Ford dealerships are charging $600 to many thousand dollars to change the spark plugs within the 5.4L, 4.6L and 6.8L engines which have the two-piece Motorcraft spark plugs. Why? Because the plugs commonly stick and break, and it will take lots of time and work to extract the debris in the spark plug holes. In some instances, it could even be needed to remove the cylinder heads to finish their repair.
Ford’s Technical Service Bulletin 08-7-6
Ford Technical Services Bulletin 08-7-6 addresses the advisable removal process for these spark plugs, as well as the repair procedure if one or even more plugs break ( Click Here to See Ford TSB 08-7-6). NOTE: TSB 08-7-6 supersedes the earlier TSB 06-5-9 that also covered the same matter. The difference is that the newest TSB says to remove the spark plugs once the engine is COLD (at room temperature). The older TSB said to remove the spark plugs when the engine was WARM (not COLD and never HOT). They principle was that a warm engine generates a bit more clearance amongst the plug shell and cylinder head. But eliminating spark plugs on a warm engine with aluminum cylinder heads also increases the potential risk of damaging the threads while in the spark plug hole, as well.
Ways to Remove the Motorcraft Spark Plugs So They do not Break
First, ensure the engine is at area temperature (COLD).
Loosen every single spark plug about 1/8 to 1/4 turn. Then Quit!
Spray some WD-40 or penetrating oil into every spark plug nicely. Enable the oil to soak in to the threads so it could possibly loosen any carbon or corrosion throughout the electrode shell. Wait not less than 15 minutes, or lengthier (overnight is proposed if your plugs have over 80,000 miles on them).
Immediately after the penetrating oil has had time to operate, gradually loosen every single spark plug, applying not more than 35 ft. lbs of torque for your wrench. If a plug sticks, retighten it half a turn, apply extra penetrating oil, wait, then consider yet again. The plugs might squeal and groan, but will hopefully come out without the need of breaking.
Eliminating carbon from within the combustion chamber just before shifting the spark plugs could also decrease the chance in the spark plugs sticking and breaking. Making use of Leading Tier gasoline or including a fuel system cleaner (such as Chevron Techron or equivalent) for your fuel tank frequently might help lower carbon buildup inside the combustion chamber. If you engine has a lot of miles on it, and/or is using oil, utilizing a Best
Cleaner therapy to remove carbon prior to shifting the spark plugs is extremely advised.

Various aftermarket efficiency organizations (including Roush) also sell a more robust one-piece replacement spark plug for these engines that won’t break. Note: the Champion spark plugs demand a greater 5/8-inch socket to install (the original Motorcraft plugs have a 9/16-inch hex shell).
Apply nickel anti-seize to the outer surface with the decrease electrode shell (the smooth element) ahead of setting up the plugs.
Tighten the brand new spark plugs to 25 ft. lbs (34 Nm).
Replacing the rubber boot that fits in between the coil and spark plug is likewise advised to avoid arcing which can bring about misfires.
