Why is my Toyota using oil?
Why is my152 toyota corolla diesel using oil after doing6000 km with only60000 km on clock
Our answer:
Hi Patrick,
While that could signal an issue within the engine itself, we know that that 1.4 diesel engine can develop an oil leak in the cylinder head cover gasket, so hopefully that's your issue. Inspect the engine or get a good mechanic to look at it for you.
