Engine Overview and Common Failures
The weight of the 3S-FE engine according to the catalog is 145 kg. The engine number is located at the junction of the block with the gearbox. This unit is very reliable, but there are many reviews on the internet about the destruction of such engines. The problem most often concerns engines of recent years of production and its essence is as follows: due to poor quality bolts, a connecting rod breakage occurs, which then punctures the block. Timing belt breakage The timing belt is heavily loaded here: in addition to the camshaft, it also rotates the water pump and oil pump. Therefore, there are many reasons for breakage, fortunately the valves usually do not bend. Oil consumption After 200,000 km, the oil rings often become clogged and oil consumption appears, and until you decide to overhaul it, it can reach one liter per 1000 km of mileage. Minor breakdowns This is an old engine, usually with high mileage, and minor breakdowns occur constantly. The ignition system regularly malfunctions, but this mainly applies to the first modifications, the supports of the power unit have low reliability, as well as its lambda probe. Since there are no hydraulic compensators, valve clearances need to be adjusted every 100,000 km.
