I think I'm hearing hammering - one cylinder? - mostly around 1800-2200 rpm. More noticeable when engine is warmed up. Could be my imagination. Did a search on "hammering" and "knock" which resulted in a few odds and ends related to injectors and timing.
Engine is bone stock '96 12v, 215 pump, 108k miles. Last oil analysis was AOK 2k miles ago.
Any words of wisdom?
