Problems:

Oil consumption

The Toyota 2AZ-FE engine is known for excessive oil consumption, especially in older models. This can be due to piston ring wear or valve stem seal issues.

Head gasket failure

Some 2AZ-FE engines have experienced head gasket failures, which can lead to coolant leaks and overheating issues.

Timing chain tensioner

The timing chain tensioner can fail, leading to a rattling noise on startup and potential timing chain issues if not addressed.

Engine mounts

The engine mounts in the Scion tC can wear out or fail, causing excessive engine vibration and noise.

Valve cover leaks

The valve cover gasket may deteriorate over time, leading to oil leaks from the top of the engine.

Water pump failure

The water pump can fail, leading to coolant leaks and potential overheating.

Knocking noise

Some users report a knocking noise from the engine, which can be due to piston slap or connecting rod issues.

Carbon buildup

Carbon buildup in the intake manifold and on the intake valves can cause rough idling and performance issues.

Water pump failure

The water pump in the 2AR-FE engine may fail prematurely, leading to engine overheating if not addressed.

Valve cover gasket leak

The valve cover gasket can deteriorate over time, causing oil leaks and potential engine bay contamination.

Carbon build-up

Like many modern engines, the 2AR-FE can suffer from carbon build-up on intake valves, affecting engine performance and efficiency.

Timing chain tensioner noise

The timing chain tensioner can become noisy, leading to a rattling sound on startup or during operation.

Exhaust manifold cracks

The exhaust manifold may develop cracks over time, which can cause exhaust leaks and increased engine noise.

Fuel injector issues

Fuel injectors may become clogged or fail, leading to poor engine performance and reduced fuel efficiency.
