Disadvantages of the GM LFX engine
- This is a fairly reliable power unit, except that its fuel consumption is too high.
- The only weak point of the motor is not the highest resource of the timing chain.
- Those who like sharp starts from a place may need to replace the chains already by 50,000 km.
- Like all direct injection engines, it is prone to valve deposits.
- Try not to allow severe overheating, or the grease will come out of all the seals.
