Engine Tapping
#1
![Default](/forum/images/icons/icon1.gif)
Hiya,
I have a 2004 Silverado with the 4.3 V6 engine.
I was driving, and the oil pressure warning light came on, and the gauge dropped to zero. I babied it the last few miles to my work's shop, but it had developed a tapping by the time I got there.
I tore the engine apart, and replaced the cam, lifters, and oil pump. Checked all the rods for bend, but there was none, so didn't replace them.
I just got it all back together yesterday, and the noise came back after idling for just about 5 min.
I am a carpenter by trade, and not a mechanic, but to my ears, it is for sure a top end noise, and mechanical sounding in nature.
I am out of ideas, so i though you good folk might have some thoughts.
Thanks in advance,
Fred

I'd sure be looking at that crankshaft as that is where the starvation starts.
When a oil light comes on, the VERY FIRST thing you do is shut the engine down.
