V10 Ford Engine Problems

63

Ford’s 6.8L (413 cubic inch, found in E-Series and F-Series trucks) V10 is part of the company’s “modular” engine family (1991 to present), and represents the largest evolution of the design. One way to think of the V10 is as a 4.0L V6 with four extra cylinders or as a 5.4L V8 with two more cylinders.

Basic Design

Ford’s truck V-10 is an iron-block, overhead-cam aluminum head design that uses centrally mounted spark plugs and direct fire ignition. Almost all valvetrain and accessory components are shared with the 5.4L, making the design fairly stout and easy to repair. However many 1997-2008 engines have a fatal flaw in the cylinder head.
