Tapping & Whistle
99 Silverado 5.3 Vortec
Have had a tapping sound for a few weeks now. Couple of days it was so loud I actually shut the truck off in fear something awful was happening. Once I punch the gas a few times, hard, it goes away. I am think an oil blockage or oil pressure issue? It only goes away if I punch it.
Also, after starting I hear a whistle sound, which can be heard in the video. I warmed up the engine so the tapping is at a minimal so you can hear it.
Thoughts?
