Disadvantages of the GM LTG engine
- This turbo engine has been produced for quite a long time and many of its shortcomings have already been corrected;
- First of all, the unit is afraid of detonation and its aluminum pistons simply burst;
- Like all direct injection engines, it suffers from carbon deposits on the intake valves;
- The timing chain does not have a large resource either, sometimes it stretches up to 100,000 km;
- Also, grease leaks are very common here, and especially from under the timing cover.
