Remanufactured 5.4L 3 valve Engines Lincoln Navigator

From 2005 and on the Lincoln Navigator used the 3 valve 5.4 liter V8 engine. For those in the know, the engine I’m speaking of was extremely popular and use extensively throughout Ford’s, Mercury’s and Lincoln’s Car/SUV, Truck lineups.

The most intelligent way to buy the described engine for said vehicle is to purchase a Remanufactured 5.4L 3 valve Engine Lincoln Navigator. Let me explain. This engine came in 2 valve per cylinder models, 3 valve/cylinder and 4 valve/cylinder variants. Here is why a professionally remanufactured 5.4 liter 3 valve/cylinder Ford engine is your best value and least expense long term solution.

Three [#3] valve 5.4 liter engines built before Oct of 2007 had an issue with spark plugs “Blowing” out of the spark plug hole/threads, or, the spark plugs corroding and “pulling” the threads out of the aluminum head during spark plug removal.

The problem occurred on all 5.4 liter SOHC engines [single overhead camshaft]. The real problem turns out to be where the spark plugs thread into the ‘aluminum heads’, there are not enough threads in the head. Because aluminum is being used very successfully in many other brands of engines, the problem was definitely in the head design.

So, A. Because less threads are holding the spark plug into the soft aluminum head, the aluminum threads fatigue under the intense compression pressures and the plug literally blows out of the threaded hole, threads and all. B. Because there are less threads, and dissimilar metals [the head is aluminum and the plug base is steel] can cause a ‘cold weld/fusion’ situation if anti-seize thread compound was not applied to the threads on the spark plug.

There is a solid permanent solution available. A new set of stainless steel threads inserted into the aluminum hole [called Time-serts]. Effectively solving the ‘blown out’ plug issue. It is more work to perform during a remanufacturing job. It takes some special tools and more machine work time to make an effective change. Do we charge more? Absolutely not.

It’s part of the job, as it is in any engine remanufacturing job we perform. Every known update and factory improvement is incorporated in the job, building pure value into the engine and lowering the cost in relation to the miles delivered to the price. We sell you a BETTER engine than came in the vehicle from the factory.
