Disadvantages of the B12D1 engine
This power unit has no obvious flaws and is straightforward and dependable.
Only the Check Engine’s winter appearance and noises under the hood are discussed on specialized forums.
The resource of hydraulic lifters is significantly reduced by lubrication savings, sometimes up to 50,000 kilometers.
Because the valves bend when the timing chain jumps, it’s also critical to keep an eye on its condition.
The remaining issues are associated with attachment failures or overheating.
