What are some common problems with the Ford 7.3-Liter Gas Engine?

Ford's 7.3-liter V8 engine, known informally as "Godzilla," was introduced in 2020 as a high-performance choice for heavy-duty trucks. While it boasts significant displacement and efficient low RPM operation, several owners have reported issues with this engine. Here, we explore these common concerns and offer guidance on addressing them.

Common Problems and Complaints with the Ford 7.3 Gas Engine

Rough Idle: Many owners report a rough idle with the 7.3 engines. Potential causes include dirty injectors, vacuum leaks, or faulty idle air control valves. If your truck exhibits this issue, it's advisable to have it inspected to pinpoint and rectify the cause.

Engine Knock: A knocking or ticking sound is another frequent concern. This issue may stem from low oil pressure, worn bearings, or piston problems. Prompt attention to these sounds is crucial for maintaining engine health.

Oil Leaks: Oil leaks, especially from valve cover gaskets and the oil pan gasket, are relatively common. These leaks can occur due to age or wear and tear, and should be addressed to avoid further complications.

Fuel Filter Clogging: The complexity of the 7.3's fuel system sometimes leads to issues like clogged fuel filters, malfunctioning fuel pumps, or issues with the fuel pressure regulator. Symptoms such as difficulty starting the engine or poor fuel economy warrant a thorough check of the fuel system.

Overheating: Overheating in the 7.3 gas engine can be caused by a range of issues, including a faulty thermostat, clogged radiator, or water pump problems. Overheating should be treated as a serious concern, as it can lead to extensive engine damage.

Injection Pressure Regulator Valve: Problems with the Injection Pressure Regulator (IPR) Valve, including sticking, damaged seals, or sensor malfunctions, can arise and should be checked if performance issues are noticed.
