Problems:

Oil leaks
The Toyota 1GR-FE engine in the 2006 4Runner is known to develop oil leaks, particularly from the valve cover gaskets and the front timing cover.
Head gasket failure
This engine can experience head gasket issues, often noticeable through coolant loss, white smoke from the exhaust, or overheating.
Excessive oil consumption
Some owners report excessive oil consumption, which could be due to worn piston rings or valve seals.
Timing chain noise
The timing chain on the 1GR-FE engine may produce noise if it becomes worn or if the tensioner fails, leading to potential timing issues.
Faulty oxygen sensors
Oxygen sensors in this engine may fail, causing poor fuel economy and triggering the check engine light.

The cast iron exhaust manifolds are prone to cracking, which can lead to exhaust leaks and reduced engine performance.
Ignition coil failure
The ignition coils on the 2UZ-FE engine can fail, leading to misfires and rough running conditions.
Cooling system issues
Over time, components like the radiator, water pump, and thermostat can fail, leading to overheating issues.
Throttle body problems
Carbon build-up in the throttle body can cause poor idling and throttle response problems.
Fuel injector issues
Fuel injectors can become clogged or fail, leading to poor engine performance and increased fuel consumption.
Oxygen sensor failure
The oxygen sensors can fail, causing the engine to run inefficiently and potentially trigger the check engine light.
