The weight of the H25A engine assembly is 170 kg. The engine number H25A is located at the junction of the block and the oil pan. The timing mechanism consists of three chains and three hydraulic tensioners, which are very demanding in terms of the quality of the oil used and the schedule for its replacement. Trying to save on these can result in tensioner failure and catastrophic chain skipping, which is fatal for the engine. Oil consumption is often accompanied by excessive oil consumption after 150,000 km, and it tends to increase rapidly over time. The main cause is not worn rings or valve caps, but rather a clogged oil labyrinth in the valve covers, which is part of the crankcase ventilation system. Oil leaks are one of the most common problems with engines in the N series. The oil often leaks from the front engine cover, both crankshaft seals, or through the gaskets of the oil channel at the junction of the block with the crankshaft bed or oil pan. Other weaknesses of such engines include an unreliable mass airflow sensor and a quickly clogging EGR valve, as well as frequent rupture of its connecting pipe.
