The weight of the Z20LET engine according to the catalog is 160 kg. The engine number Z20LET is located at the junction of the block and the gearbox. The weak point of the engine is considered to be the oil seal caps, which often need to be replaced. Additionally, the exhaust manifold regularly develops cracks, but it can usually be welded. The timing belt is designed for a mileage of 60,000 kilometers, and in case of valve failure, it causes 100% damage. Among minor inconveniences, we can include regular oil leaks from under the valve cover. In case of a whistle during idle, the manufacturer has provided a bulletin.
