The mechanical efficiency of your powertrain is governed by a high-precision dance of intake and exhaust components that must operate in perfect synchronization. Maintaining a clinical valve assembly is the most critical factor in preserving the fuel economy and power delivery of your modern engine. For owners of the versatile Ford Explorer, these parts must withstand the extreme pressures of the EcoBoost combustion cycle.

Easy Steps to Check Your Valve Assembly

1. Perform a Compression Test

Use a gauge to check the internal pressure of each cylinder; a low reading often indicates a leaking or burnt valve.

2. Listen for Ticking

Use a mechanic’s stethoscope on the valve cover to identify rhythmic clicking that signals excessive valve assembly clearance.

3. Remove Valve Covers

Gain visual access to the top of the assembly to check for broken springs or loose retainers that could cause failure.

4. Check Stem Play

Gently move the valve stems side-to-side; any visible "wobble" indicates worn guides that require clinical repair immediately.

5. Visual Carbon Check

Use a borescope through the spark plug hole to inspect the valve faces for heavy carbon deposits or visible thermal damage.

6. Verify Spring Height

Measure the free height of each spring to ensure they haven't "shrunk" or lost their tension due to excessive heat soak.
