Currently in the shop: 2012 GMC Terrain with the notorious timing chain rattle. These 2.4 Ecotec motors typically see oil consumption and timing chain guide issues. If left alone it will cause catastrophic failure! This one had a broken guide with less than 100k miles. Many GM cars use this motor, if you think you’re experiencing timing chain noise give us a call! 919-451-4566
