The weight of the G25A engine according to the catalog is 170 kg. The engine number G25A is located at the junction of the block and gearbox. There are no questions about the reliability of the engine, but there are problems with service and spare parts. The most common issue for owners is frequent oil leaks from gaskets and seals. The timing belt lasts around 100,000 km, and in case of a valve failure, it bends in 100% of cases. The reason for fluctuating engine rpm is usually due to throttle or ECU contamination. There are no hydraulic compensators, and valve clearances need to be adjusted every 40,000 km.
