Are there any problems with the Ford 6.8L V10 engine?
If you buy a used Ford with a 6.8L V10 engine, there’s a good chance it has already run into this problem or will in the future. That’s because this issue is caused by a design flaw that allows the aluminum threads holding the spark plugs in place to expand and create gaps.
How big is the V10 engine in a Ford truck?
The 6.8 L (413 CID) SOHC V10 is a variation of the Modular family created for use in large trucks. Bore size is 90.2 mm (3.552 in) and stroke is 105.8 mm (4.165 in), identical to the 5.4 L V8. Both 2-valve and 3-valve versions have been produced.
Why are my spark plugs not working on my Ford V10?
That’s because this issue is caused by a design flaw that allows the aluminum threads holding the spark plugs in place to expand and create gaps. Over time, the threads holding the spark plugs in place can also weaken or become threaded, resulting in the ejection of the spark plugs themselves.
