I received a diagnostic code of P0325 TWICE by two different professional technicians. I ordered an OEM knock sensor, hired a technician to replace the knock sensor, drove about 10 miles and the check engine light came back on. Then, I received a diagnostic code of P-1101, and the recommended solution is to replace the intake manifold and all necessary gadgets. After speaking with professional technicians and doing thorough online research, I discovered that General Motors issued a service bulletin No. 19-NA-101, dated July 2024, covers certain 2013\u20132019 model vehicles (including Buick Encore with 1.4L turbo) for oil consumption and/or leaks caused by a missing non-return valve in the intake manifold. The bulletin acknowledges that the intake manifold design on these 1.4L turbo engines has a non-return (check) valve or PCV system component inside the manifold that can fail or go missing, leading to issues like boost/vacuum leaks, oil consumption, engine performance faults. \u2022The PCV valve is non-serviceable (you can\u2019t replace it separately), meaning the only fix is replacing the manifold \u2014 which GM calls out in the bulletin. If GM or Buick hasn't issued a recall they should offer goodwill assistance especially since this is a defect on their end.","products":[{"type":"Vehicle","productYear":"2019","productMake":"BUICK","productModel":"ENCORE","manufacturer":"General Motors, LLC"}]}]}
