2013 Terrain timing chain, need some advice.
I just replaced the timing chain, tensioner on my girlfriends terrain. Did everything by the book. Went surprisingly too well and started up, runs great. Now we got on the highway tonight and punched it a bit, sounds like it’s got a intake leak, as if it were to have a cold air. Just noisy now and wasn’t there before. Could this be timing too retarded or advanced? Runs great though, no misses or surging. Anyone had this happen?
