The 2.0-liter General Motors LSJ compressor engine was assembled in the USA from 2003 to 2007 and installed on charged modifications of the Chevrolet Cobalt SS and Saturn Ion Red Line Edition. This motor was distinguished from its predecessor LK9 by the presence of an Eaton M62 compressor instead of a turbine.
The first generation of GM Ecotec includes: LSJ, L61.

Disadvantages of the GM LSJ engine
- Most of the complaints about this unit are associated with jumping idle speeds.
- In some cases, you have to clean the throttle and intake every 10,000 km.
- In second place is squeezing oil through the dipstick during sharp acceleration from a standstill.
- The weak points of this motor also include not the highest resource of the timing chain.
- And don’t forget to renew the oil in the compressor or it won’t last very long.
