Disadvantages of the Renault B4A engine
The engine is largely commended on specialized forums; no flaws were discovered;
Since all aluminum engines are concerned about overheating, it is crucial to keep an eye on the cooling system.
Every 100,000 kilometers, the valves must be adjusted because there are no hydraulic lifters.
The primary issue, though, is that there are only consumables and no spare parts.
