A knocking engine in your 1990 Olds 88 could be due to several issues, such as low oil levels or poor oil quality, which can lead to insufficient lubrication. It might also indicate problems with the engine's bearings, piston slap, or even pre-ignition caused by using the wrong fuel type. Additionally, a failing timing chain or belt can cause knocking sounds. It's important to diagnose the problem promptly to avoid further damage.
