Problem overview

Some Toyota 4Runner owners report experiencing oil leaks from the timing cover, which can lead to oil dripping onto various engine components. This common issue often necessitates the removal of several parts from the front of the engine, such as the alternator and valve covers, for proper repair. Repair costs for this issue can vary significantly, with quotes from dealerships and local shops ranging from $3200 to $4300. While some DIY enthusiasts attempt to reseal the timing cover to save on expenses, it is crucial to fully understand the repair process beforehand. Additionally, monitoring the leak and accurately identifying its source is essential, as the situation may deteriorate if left unaddressed. Some owners have noted that the oil leak can appear as oil splatter from the axle, potentially misleading them to believe the leak originates from the CV joint. Conducting a visual inspection of the engine area can help reveal oil build-up and pinpoint leakage sources.
