Fix Ford 4.6L / 5.4L 3V Cam Phaser Noise — Plug-and-Play Kit with Tuner

Ford 4.6L and 5.4L 3-valve engines commonly develop a knocking noise from the front timing chain area over time. This is caused by the cam phaser moving back and forth uncontrollably. In addition to the noise, the failing cam phaser sends error codes to the vehicle's computer and can push the engine into limp mode — resulting in rough idle, low power, and poor fuel mileage. In extreme cases, the phaser pin fractures the phaser housing and the entire assembly can fail. This problem is well-known on F-150, Expedition, Navigator, and other trucks and SUVs equipped with the Ford 5.4 Triton engine, as well as 4.6L 3V applications.

The Livernois LPP823113 Ford 4.6L / 5.4L 3V Cam Phaser Noise Repair Complete Kit eliminates the cam phaser noise by converting the variable cam phaser to a solid hub design — no moving parts, no internal mechanisms to fail. This kit includes the Livernois cam phaser lockouts, the MyCalibrator Tuner (plug-and-play via OBD-II, tune loads immediately — no email submission, no wait for a custom tune file), the Livernois Timing Chain Wedge Tool, and 2 OEM Quality Phaser Bolts. The kit is CARB certified under Executive Order D-752 and is legal for use in all 50 states. US Patent # 9,850,786 B2. Designed for Ford OEM cam phasers only. One kit per vehicle.

How to Tell Which Phasers You Have

Most buyers cannot reliably tell from the outside of the vehicle. The phaser style is usually confirmed by visual inspection once the valve covers are removed, by service history, or by knowing which replacement phasers were previously installed.

• Prior repair history matters. If the truck has had cam phasers replaced before, do not assume it still has Ford OEM phasers.
• Mixed phasers are possible. One Ford OEM-style and one Dorman-style phaser can exist on the same vehicle — this is exactly why the LPP822133 Deluxe Kit exists.
• LPP822133 is the "avoid ordering the wrong kit" option — not just a more expensive alternative. It includes lockouts for both Ford OEM and Dorman phasers, so the repair can proceed regardless of which phasers are installed.

Which Ford 4.6L / 5.4L 3V Cam Phaser Kit Do You Need?

For Ford 4.6L and 5.4L 3-valve applications, the correct kit depends on which cam phasers are installed — not just the engine size. If you are not sure which phasers you have, choose the Deluxe kit or call Livernois at 313-561-5500 before starting the repair.

Why Choose Livernois Over Other Ford 5.4 Cam Phaser Lockout Kits

Other companies sell Ford 3V lockout kits. Livernois gives buyers a complete, CARB EO-backed repair path with the correct lockout kit, included calibration, installation support, and routing for Ford OEM, Dorman, or unknown phaser setups.

Livernois Motorsports & Engineering has been engineering, testing, and manufacturing performance and repair solutions in the USA since 1949. The LPP823113 is not a parts kit — it is a complete repair solution built around a patented lockout design, plug-and-play calibration, and a CARB Executive Order certification that many competing kits cannot claim. Every component is selected to get the repair done correctly the first time, including the Timing Chain Wedge Tool that in the standard installation process is designed to hold the timing chains in place so the lockouts can be installed without removing the front cover.

• CARB Executive Order D-752 — 50-state legal, including California — many competing Ford 3V lockout kits explicitly state they are not legal for use in California. LPP823113 is certified for covered applications.
• Complete kit — not just parts — includes lockouts, calibration tuner, timing chain wedge tool, and phaser bolts. Competing kits often require the buyer to source the tune separately or wait days before the vehicle can be started.
• Plug-and-play MyCalibrator Tuner included — tune loads immediately through the OBD-II port. No email submission, no phone call, no 3–5 business day wait for a custom tune file before you can start the vehicle.
• Correct-kit routing for OEM, Dorman, and unknown phaser setups — Livernois offers separate kits for Ford OEM phasers (LPP823113), Dorman phasers (LPP823123), and mixed or unknown setups (LPP822133 Deluxe). Most competing kits are one-size-fits-all and do not address phaser compatibility.
• US Patent # 9,850,786 B2 — proprietary Livernois lockout design
• Timing Chain Wedge Tool included — in the standard installation process, designed to hold the timing chains without removing the front cover or front dress
• Engineered, tested, and manufactured in the USA since 1949 — not a rebadged import kit
• Phone support: 313-561-5500 — Livernois technical staff available to confirm fitment and kit selection before you order

Ford 5.4L 3V Cam Phaser Noise Repair

The Ford 5.4L 3-valve engine — commonly referred to as the 5.4 Triton — is the most common application for the LPP823113. Cam phaser knock on 5.4L 3V trucks, including the F-150, Expedition, and Navigator, is a well-documented failure mode that causes limp mode, rough idle, and poor performance. The LPP823113 is a proven Ford F-150 cam phaser kit with tuner included, designed to get the vehicle out of limp mode and return it to normal operation. Use the Vehicle Fitments tab on this page to confirm your exact year, make, model, and engine before ordering.

Ford 4.6L 3V Cam Phaser Noise Repair

The LPP823113 also applies to Ford 4.6L 3-valve engines that have developed cam phaser noise or cam phaser codes. The same solid hub lockout design and plug-and-play MyCalibrator Tuner are included. The correct kit still depends on whether your 4.6L 3V application has Ford OEM or aftermarket Dorman cam phasers — use the kit selector table above if you are not sure. Use the Vehicle Fitments tab on this page to confirm fitment for your specific year, make, model, and engine.

If the Timing Cover Is Coming Off — Also Consider

If the cam phaser repair involves deeper timing or front-cover work — including higher-mileage engine service, a rebuild or repair situation, or any supercharged or performance application — consider adding an oil pump upgrade while the front of the engine is accessible.

• LPP701109 — Oil Pump with Billet Gears — Complete oil pump with billet gears. Recommended when the job includes deeper timing or front-cover work, higher-mileage engine service, rebuild or repair, or supercharged and performance use. Best choice when the oil pump is being replaced as part of the same job.
• LPP701128 — Billet Oil Pump Gears — Billet gear set only. For buyers who have a new or serviceable pump and prefer to upgrade the gears only, or when an installer requests the gear-only option.

These are not required for the cam phaser lockout repair itself. They are recommended additions when deeper engine access is already part of the job scope.

Is This the Same as a Ford 5.4 Cam Phaser Delete Kit?

Yes, in the way most buyers use that term. Many buyers search for a "5.4 cam phaser delete kit" or "Ford 3V VCT lockout" when looking for this type of repair. The Livernois LPP823113 uses precision-machined billet aluminum lockouts to convert the variable cam phaser to a solid fixed gear — eliminating the movement, the noise, and any internal mechanisms that can fail. The MyCalibrator Tuner then recalibrates the vehicle's computer to operate correctly with the fixed cam timing and returns the vehicle to normal operation. The result is what buyers commonly refer to as a cam phaser delete or lockout kit — with plug-and-play tuning included and CARB D-752 certification for all 50 states.

Vehicle Fitment — Ford 4.6L and 5.4L 3-Valve Engines

This product is intended for Ford cars and trucks with 4.6L or 5.4L 3-valve engines in a cam phaser noise repair situation. Use the Vehicle Fitments tab on this page to confirm your exact year, make, model, and engine before ordering. Do not assume fitment based on engine size alone.

50 State Legal — CARB D-752 Certified

Unlike generic lockout solutions, the Livernois LPP823113 cam phaser noise repair kit is backed by CARB EO approval for covered applications. That means the complete repair path has gone through emissions review, giving you a more credible, compliance-conscious solution instead of a parts-only shortcut. Certified under CARB Executive Order D-752. Legal for use in all 50 states, including California. US Patent # 9,850,786 B2.

Livernois complete kits include the required calibration path and CARB EO-backed compliance support for covered applications. Many generic lockout kits are parts-only solutions and may not include emissions-approved calibration support.

Cam Phaser Noise in Modified or Performance Engines

The use of aftermarket valve springs with increased spring pressure, as well as aftermarket camshaft profiles, do not allow the factory Ford cam phaser to function properly and may even cause it to fail. The increased spring pressures and more aggressive camshaft ramp rates cause the phaser to behave erratically. The factory phaser cannot control these added pressures, and in the majority of cases the phaser will emit a knocking noise as the phaser struggles to control camshaft position. This can also cause erratic idle, poor fuel mileage, and power loss.

For vehicles with aftermarket valve springs or camshaft profiles, eliminating the cam phaser with the Livernois lockout kit and included tune removes the variable cam timing system from the equation — a common and effective repair path for modified Ford 4.6L and 5.4L 3V applications.

Frequently Asked Questions

Is this for 3.5L EcoBoost cam phaser problems?

No. This page is for Ford 4.6L and 5.4L 3-valve cam phaser noise repair. If you have a 3.5L EcoBoost, confirm the correct repair path before ordering.

What causes Ford 5.4 cam phaser noise?

Over time, Ford 4.6L and 5.4L 3-valve engines develop cam phaser knock from the front timing chain area. The variable cam phaser loses the ability to control cam position, causing it to move erratically. Symptoms include knocking or rattling at idle, cam phaser codes, limp mode, rough idle, low power, and poor fuel mileage.

Does LPP823113 work with Dorman cam phasers?

No. LPP823113 is designed for Ford OEM cam phasers only. If your vehicle has aftermarket Dorman cam phasers, use the LPP823123 Dorman cam phaser noise repair kit (complete kit with tuner and tool), or the LPP823124 Dorman lockout pair if you already have the tuner and timing chain wedge tool. If you are not sure which phasers are installed, use the LPP822133 Deluxe Cam Phaser Noise Repair Kit, which covers both OEM and Dorman phaser applications.

What if I don't know whether I have Ford OEM or Dorman cam phasers?

Choose the LPP822133 Deluxe Cam Phaser Noise Repair Kit. It includes lockouts for both Ford OEM and aftermarket Dorman phasers, so you are covered regardless of which phasers are installed. You can also call Livernois at 313-561-5500 before starting the repair.

What if I have one Ford OEM phaser and one Dorman phaser?

This is not uncommon. If your vehicle has a mixed phaser setup, use the LPP822133 Deluxe Cam Phaser Noise Repair Kit, which covers both phaser types in one kit.

Does this kit include the tuner?

Yes. LPP823113 includes the MyCalibrator Tuner. It is plug-and-play via OBD-II — the tune loads immediately with no email submission and no wait for a custom tune file. Install the tune before starting the vehicle after lockout installation.

Does this kit include the timing chain wedge tool?

Yes. The Livernois Timing Chain Wedge Tool is included. In the standard lockout installation process, the wedge tool is designed to hold the timing chains in place so the lockouts can be installed without removing the front cover. A pull cord is left hanging out of the top of the engine for easy removal after reassembly.

Is this kit CARB legal?

Yes. LPP823113 is certified under CARB Executive Order D-752 and is legal for use in all 50 states, including California. Many competing cam phaser lockout kits are not California legal.

Should I buy the Deluxe kit instead of LPP823113?

If you are confident your vehicle has Ford OEM cam phasers, LPP823113 is the correct kit. If you are unsure, or if your vehicle may have Dorman phasers or a mixed phaser setup, choose the LPP822133 Deluxe Cam Phaser Noise Repair Kit to avoid being stopped mid-repair with the wrong lockout style.

What if my cam phasers are damaged or beyond lockout repair?

If the existing phasers are damaged or questionable, see the LPP823116 2004-2015 Ford 4.6L/5.4L 3V assembled cam phasers for an alternate repair path.

What if I only need the lockout pair — I already have the tuner and tool?

If you already have the MyCalibrator Tuner and the Livernois Timing Chain Wedge Tool and only need the lockout pair, use LPP823108 for Ford OEM phasers ($79.99) or LPP823124 for Dorman phasers. If you are not sure which phasers you have, choose the complete kit (LPP823113 or LPP823123) or call Livernois at 313-561-5500 before ordering.

Is this one kit per vehicle?

Yes. One kit covers one vehicle — both cam phasers on the engine.

Do I need to reinstall the factory tune before dealer service?

Yes. The tuner must stay with the vehicle at all times. Before taking the vehicle to any dealer for service, you must use the MyCalibrator Tuner to re-install the factory tune. Any factory PCM updates performed by a dealer while the lockout tune is active can prevent the lockout tune from loading again if the vehicle has not been returned to stock first.
