Disadvantages of the TB45 engine
- This engine has excellent reliability and service life, but very high fuel consumption;
- Ignition problems are often discussed on the forums, but everything is simple and cheap there;
- Many are faced with shaking at idle, valve adjustment helps;
- By a run of about 200 – 250 thousand kilometers, the timing chain is often extended;
- Beware of overheating, compression may disappear in the motor and oil burn may begin.
