Disadvantages of the 7M-GTE engine
- A well-known engine problem is a breakdown of the cylinder head gasket in the area of the 6th cylinder.
- One of the solutions is grinding the mating surface for a metal package.
- Also, the engine resource is reduced by the insufficient performance of the oil pump.
- Another weak point is the outdated and capricious ignition system.
- Every 50 thousand km it is necessary to adjust the valves using the selection of washers.
