Disadvantages of the GM LEA engine
- Most of the complaints about this unit are related to oil consumption due to the occurrence of rings.
- In 2014, it received an updated piston and the problem became less common.
- Another cause of oil burning can be a clogged crankcase ventilation system.
- The timing chain does not have a high resource and often needs to be replaced by 150,000 km.
- As with all direct injection engines, the intake valves are covered with soot.
