On the 1997-2008 Ford Expedition 5.4L Triton, the 5.4L Triton 2-valve V8 in 1997-2008 Expeditions is notorious for spark plugs ejecting from the aluminum cylinder heads. The 2-valve heads have only 4 threads holding each spark plug, which is insufficient for the clamping force needed. Over time, the threads strip and the spark plug launches out of the head under combustion pressure, taking the ignition coil with it. This typically happens when spark plugs are removed and reinstalled, or spontaneously at high mileage.

This issue also affects: Acura MDX, Acura TL, Audi Q7

Common Symptoms

Loud popping noise from engine
Spark plug and coil found on top of engine
Engine misfire on one cylinder
Hissing noise from plug hole
Loss of power and rough running

How to Fix

If a spark plug has blown out, a thread repair kit (Time-Sert or Heli-Coil) can permanently restore the threads without removing the cylinder head ($150-400 per plug at a shop). Prevention: Use anti-seize on spark plug threads, torque to exactly 22-25 ft-lbs (do not overtighten), and avoid changing plugs when the engine is hot. Time-Sert inserts are considered the superior repair ($30-50 per kit DIY). Some shops specialize in this repair and can do it in 30-60 minutes per plug.
