Ford Expedition Engine Valve Lifter Guide (2016-2024)
Addressing ticking noises and performance issues in your 3.5L EcoBoost Expedition.
- A ticking noise is the most common symptom, but be sure it's not the more common VCT phaser rattle covered by Ford's TSBs.
- This is a very difficult and time-consuming repair; it is not recommended for a DIY mechanic.
- Always replace all 24 lifters at the same time, along with other timing components if they show wear.
- Aftermarket brands like INA, Melling, and Sealed Power are reputable alternatives to OEM parts.
Is Your Expedition Making a Ticking Noise?
A rhythmic ticking or tapping sound from the engine, especially when cold, is a primary symptom of a failing valve lifter. This noise occurs when a lifter can't hold oil pressure, creating a small gap in the valve train. While other issues can cause similar noises, a bad lifter is a common culprit. You might also notice a general decrease in engine performance or, in severe cases, a check engine light with misfire codes.

Many 2017-2020 Expeditions with the 3.5L EcoBoost engine are known for a loud rattle on cold starts that lasts for a few seconds. This is often caused by worn Variable Camshaft Timing (VCT) units, not the lifters. Ford has issued Technical Service Bulletins (TSB 23-2143 and 20-2166) for this specific issue, which involves replacing the VCT phasers. 🎬 Watch: Understanding the TSB for EcoBoost start-up ticking. It's crucial to diagnose the sound correctly, as the repair is different.
Choosing the Right Aftermarket Valve Lifter
When replacing valve lifters, you have a choice between OEM and aftermarket parts. For a high-labor job like this, quality is key. You don't want to do the job twice. Here's a look at the available aftermarket brands.
- INA: INA is a highly respected German manufacturer, often supplying original parts to many automakers. They are known for precision and quality, making them a top-tier aftermarket choice that is often equivalent to OEM quality.
- Melling: Melling is a well-known American brand specializing in valvetrain components and oil pumps. They are widely regarded in the mechanic community for producing parts that meet or exceed OEM specifications. Many professionals trust Melling for critical engine repairs.
- Sealed Power: A brand under Federal-Mogul, Sealed Power has a long history of providing reliable, OE-quality replacement parts for the North American market. They are a solid, dependable choice for a standard replacement and are often praised in owner forums.
Pro Tip: Since replacing lifters is a major job that requires removing the timing components and camshafts, it is highly recommended to replace all lifters at once, not just the one that failed. Mechanics also suggest replacing other "while you're in there" parts like timing chains, guides, tensioners, and VCT phasers, especially if your vehicle has higher mileage or exhibits the cold start rattle.

Frequently Asked Questions
Can I replace just one bad lifter?
While you technically can, it is strongly advised against it. A single failed lifter often indicates that others are nearing the end of their service life. Given the high labor cost to access them, replacing all 24 lifters at the same time is the most cost-effective and reliable repair.
Is a lifter tick serious?
Initially, it may just be an annoying noise. However, a collapsed or stuck lifter can lead to further engine damage over time, including accelerated wear on the camshaft lobes. This can result in a much more expensive repair down the road. It's best to address the issue promptly.
Will a thicker oil or an additive fix a noisy lifter?
In some very minor cases of a sticky lifter, an engine flush or oil additive might temporarily quiet the noise. However, this is not a permanent solution for a mechanically failed or collapsed lifter. The only true fix for a bad lifter is replacement.
What is the difference between a lifter and a rocker arm?
In your Expedition's engine, the camshaft pushes on the lifter (or lash adjuster). The lifter then acts on a rocker arm (or roller-finger follower), which in turn presses down to open the valve. They are two distinct parts that work together in the valvetrain.
