Disadvantages of the B12D1 engine
- This is a simple and reliable power unit without any pronounced weaknesses.
- On specialized forums, only noises under the hood and the appearance of the Check Engine in winter are discussed.
- Saving on lubrication greatly reduces the resource of hydraulic lifters, sometimes up to 50,000 km.
- It is also important to monitor the condition of the timing chain, since when it jumps, the valves bend.
- The remaining problems are related to overheating or attachment failures.
