What are the common problems with a 4.7 Dodge engine?

Common problems with the Dodge 4.7L engine include valve seat failure, head gasket failures, and oil sludge buildup, often triggered by the engine overheating. Overheating is a major issue that can lead to catastrophic damage, so maintaining the cooling system is critical. Other problems include external oil leaks, a poorly functioning hydraulic cooling fan, and issues with hydraulic valve lash adjusters.

Overheating and associated issues 

• Valve seat failure: The valve seats can fail and come out, causing a loss of power, misfires, and potential damage that requires a cylinder head rebuild or replacement. 
• Head gasket failure: The engine is prone to head gasket issues, especially if it overheats. 
• Clogged radiator, failed water pump, or stuck thermostat: These can cause the engine to overheat if the cooling system is not maintained.

Lubrication and internal engine problems 

• Oil sludge buildup: Sludge can form due to incomplete combustion and oil breakdown, clogging oil passages and starving the engine of oil. This is particularly common in early models and can be exacerbated by a poor PCV system. 
• Hydraulic valve lash adjuster problems: The adjusters can become plugged due to lack of oil flow, leading to improper valve train function. 
• Oil leaks: Common leak points include the valve covers, oil pan, and rear main seal. 

Other common problems

• Hydraulic cooling fan: The hydraulic fan system, powered by the power steering pump, can be unreliable. If the pump fails, the fan will not run, leading to overheating. Incorrect power steering fluid can also cause the fan to malfunction. 
• Carbon buildup: Excessive carbon can build up on the intake, valves, and pistons if the engine is not regularly serviced or is run on low-quality fuel. 
• Wear and tear: Like any engine, many problems are age-related, such as failing valve cover gaskets and other rubber components degrading over time.
