GM has updated their service bulletin regarding valve rocker arm debris to include the 2.0 liter LSY engine that is found in all 2025 and 2026 Buick Envisions. The [previous version](https://forum.talkbuick.com/t/gm-releases-service-bulletin-pip6101-for-top-end-ticking-noise-2025-2026-enclave/21) of the bulletin only listed the 2025/2026 Enclave with the 2.5 LK0 engine. As previously mentioned, the debris causes certain engine parts to not get sufficient oiling, resulting in metal-on-metal contact and the “ticking sound” mentioned by GM.
