Recipe - Ford 7.3L Godzilla Gasoline (Super Duty 2020+, E-Series cutaway 2021+)

Specific Fix build

Reliability tier: verified - verify before ordering, see /disclosure/

Tapping that follows one cylinder on the 7.3L Godzilla: check Ford program 24B27 first, separate the oil pump drive gear (lower front, 2020-2022) from the valvetrain, then lifters and the cam lobe (mode Cam lobe and lifter (tappet) wear, worst with long idling).

Parts

• 7.3L/6.8L Godzilla Valve Lifter, 2023+ (OEM) - lifter, 2023+ rows (2020-2022 tappet is a different number) (qty 2)
• 7.3L/6.8L Godzilla Push Rod (OEM) - push rod, inspect/replace with the lifter (qty 2)
• Godzilla Rocker Arm Pivot, right (current PN VC3Z-6A585-A) - rocker pivot, right (current PN) (qty 1)
• Godzilla Rocker Arm Pivot, left (current PN VC3Z-6A585-B) - rocker pivot, left (current PN) (qty 1)
• 7.3L/6.8L Godzilla Camshaft, 2023+ (OEM) - camshaft, 2023+, only if the lobe is flaked (qty 1)
• 7.3L/6.8L Godzilla Valve Cover Gasket, 2023+ (OEM) - valve cover gasket, 2023+, renewed on access (qty 1)

Install order

1. check by VIN whether the Ford 24B27 PCM update has been done (free; Ford's remedy for idle-time cam/tappet wear)
2. locate the noise: lower front at the timing cover/oil pan seam on 2020-2022 = oil pump drive gear first (SSM 50830/51330, mode Cracked oil pump drive gear (front-of-engine tick at idle, 2020-2022 7.3)); top end following one cylinder = lifter/cam
3. read misfire counters; a misfire that follows the cylinder, not the coil or plug, points to the valvetrain
4. cut the oil filter open: metal means the damage has circulated - price the bigger job
5. replace the collapsed lifter(s) and inspect the matching cam lobe; a flaked lobe means a camshaft

Expected outcome

Quiet top end and no misfire counters; the 24B27 software addresses the idle-time oil supply Ford names.

Do not

• do not condemn plugs or coils when the misfire stays with the cylinder
• do not reuse a lifter or cam with metal already in the filter
