Question 1

Timing chain stretch on the 2.4 (Ecotec)

Accepted Answer

Oil starvation from high oil consumption makes the 2.4 Ecotec timing chain stretch, causing a rattle, check engine light and cam/crank correlation codes (P0008, P0016). If the chain jumps, the engine can be damaged.

Question 2

Excessive oil consumption on the 2.4 (Ecotec)

Accepted Answer

The 2.4 four-cylinder in the 2010-2017 Equinox and Terrain burns oil through stuck piston rings, often more than a quart every 1,000-2,000 miles. GM issued special coverage for many 2010-2013 vehicles with piston replacement. Low oil levels can damage the engine.
