Ford V10 Spark Plug Problem
This engine represents large evolution of designFords V10 6.8 litre (413 cubic inch) engine used with the F53 motorhome chassis (‘A ‘class), and the E450 chassis (‘C ‘class), is part of the company’s “Modular” engine family. The Triton V10 was introduced in 1991 and is still being used today.This engine represents large evolution of design. One way is to think of the V10 is a 4.0 litre V6 engine with four extra cylinders, or as a 5.4 litre V8 with two extra cylinders, this was something that was used many years ago with motorbikes, for instance ‘Beneli the Italian’. Motorbike manufacturers of the late 1970s took a four cylinder Honda 500cc engine and added two cylinders to it, in fact it was half of another Honda 500 to make the 750cc straight 6 engine.
- Broken Ford V8 Spark Plugs. This is a review of common problems with Ford Triton spark plug replacement. We’ll also discuss a technical service bulletin released about the known issue.
- Some of the known problems in a Ford Triton V10 engine include instances where spark plugs get stuck and break in the engine. A spark plug is a part of the vehicle ignition, and when it pops up, it becomes difficult to start the car. Additionally, the engine is associated with increased consumption of fuel on acceleration.
At the heart of the problem is a unique Motorcraft spark plug with a two-piece metal shell that’s vulnerable to corrosion over time and to breaking apart on removal. Ford has known about.
Spark plug fitted into cylinder headOne of the main faults with the early V10 engines (1999 – 2005) was that the spark plugs could blow out of the cylinder head. Ford use a cast iron engine block with an overhead cam aluminium cylinder head design, that uses centrally mounted spark plugs and waste spark ignition.The aluminium cylinder heads on the two valve per cylinder engines built in the companies Windsor Ontario plant, have a fatal floor in the spark plug threads.
The cylinder head being of soft aluminium does not have much inherent strength in the first place, and also expands at a different rate to the steel spark plug threaded into it. Damaged cylinder head threadsAfter repeated heat cycling the spark plug welds itself to the threads weakening the material. The end result of this design flow is that the rear most sparks shoot out of the cylinder head while driving or get stuck while trying to remove them, and when hard steel sticks to soft aluminium, the aluminium will initially give way first. This makes the cylinder heads spark plugs strip clean out, leaving a small hole and no way to re-install a new spark plug. Also this failure can occur when removing the spark plugs for renewal.
Ford V10 Spark Plug Problem Years
A very common proplem with this engine is the coil packs sit on top of the spark plugs with a approx 4 inch boot to the spark plug. Especially when there is wet weather moisture will get the the spark plug hole and when the vehicle gets up to temp the moisture will atomize and ground out the spark plug. Sometimes it will not even need to get hot and once it starts missing won't go away.You will need to run a scan to determine which hole is misfiring. Then disconnect that coil and remove the one small bolt retaining itand pull it up out of the hole.
Then take compressed air and blow out the bottom of the hole to dry it out. Re-install coil and your problem should have gone away. If you have a scanner sometimes just clearing the codes and the miss will go away. Be careful taking it to a shop as most shops will just sell you with the fact that you have a bad coil and have it fixed in the process of selling you and installing a new coil of hey maybe they will just blow it out and seeing as it's fixed you now buy into the fact that they replaced a 'bad coil'. That is not to say that sometimes it is just a bad coil and nothing else will fix it.v8 triton is the same motor as the v10 with just 2 more cylinders so v10 or 5.4 same thing will apply.Posted on May 01, 2010. My solution for misfiring on V10: I read all the solutions here, but my engine had been completely rebuilt 15k ago, including all coil packs. Shortly after, it blew out a plug (probably due to over-tightening by the shop) and was parked for about a year.We checked the codes, but nothing there.
Checked the sparkplug boots, nothing obvious. Misfire started only when engine warmed up, was fine cold. Eventually, a coil pack failed completely, set a code, and we were able to isolate it.
When it was removed, examination showed that the bottom-most 1/4 inch of the boot had a split in it. It was so close to the engine that you could not see it without removing it. We suspect that the arcing from this to ground as the engine warmed up and the split widened is what caused the coilpack to fail.Lesson: Be sure to take the boots off COMPLETELY and examine them CLOSELY for cracks and splits. Below is a picture of the split we found:Posted on Mar 26, 2014.
