Ford 6.7L Power Stroke Engine – Assembly Torque & Bearing Clearance

Specs

Applies to 2011–2019 6.7L Power Stroke Diesel Engines. All torque-to-yield fasteners must be replaced. Bearing clearances must be MEASURED during assembly and verified against OEM limits.

Oil Type Recommendations

Use standard engine oil only during the break-in period.

• 5W-40/10W-40 for bearing clearances under 0.0035″
• 20W-50 for bearing clearances 0.0040″ and greater (race or loose-clearance engines)

Special break-in oils or additives are not required. Modern diesel engine oils already contain su icient anti-wear additives to protect bearings and piston rings during break-in.

Running Guidelines – First 1,000 Miles

• Do not allow the engine to idle for more than 10 minutes at a time
• Operate the engine at moderate RPM
• Avoid heavy load, towing, or sustained high RPM
• Change the engine oil at 1,000 miles to remove break-in debris and metal particles

Camshaft Note:

The 6.7L Power Stroke uses a hydraulic roller camshaft, which does not require a camshaft break-in procedure. No special cam break-in oil or process is necessary.

Oil Filter & Debris Inspection

Inspect the oil filter periodically during the first 1,000 miles.

• A small amount of fine metal particles in the filter is normal during break-in
• Excessive metal debris is a serious warning sign If excessive metal is found:
• Stop running the engine immediately
