Powerstroke 7.3 Anti Drain Back Plug

Part: Powerstroke 7.3 Anti Drain Back Plug

Part Number: F4TZ6666A

Manufacturer: Ford

Description:

The OEM Anti Drain Back Plug is a vital component designed specifically for the 7.3L Powerstroke Diesel engine found in Ford trucks. Its primary function is to prevent engine oil from draining back into the oil pan when the engine is off, a common issue that can lead to low oil pressure during startup. By keeping oil in the high-pressure oil system where it’s needed, this plug ensures your Powerstroke maintains proper lubrication and pressure the moment you turn the key.

On a 7.3L Powerstroke, maintaining oil pressure is critical because the engine relies heavily on oil—not just for lubrication, but also to operate the High-Pressure Oil Pump (HPOP) and the injectors. If oil drains back overnight or after extended periods of sitting, it can lead to hard starts, extended cranking, or even temporary lack of lubrication, which puts unnecessary stress on internal components like bearings, lifters, and the turbocharger.

Whether you’re doing routine maintenance or chasing down a hard-start issue, replacing a worn or missing drain-back plug is a simple yet crucial step to protect your engine. Restore proper oil pressure, reduce wear on critical components, and extend the life of your 7.3L Powerstroke—install an OEM Anti Drain Back Plug and start up strong every time.
