This beautiful Buick Enclave came in with codes for camshaft crank correlation and we could hear the belt flapping away when it was cold. We took apart the timing cover, and one of the guides has broken, and the chain was loose. We replaced the entire timing assembly, as well as all 4 intake and exhaust phasers to get this customer back on the road next day! We also ended up replacing the VVT solenoid wiring and plugs, as this is a common issue on these vehicles. Be sure to check the video for an in depth analysis as well!
