I had the the same problem. Turned out to be piston slap. I rebuilt my motor and the machine shop messed up a bore. I had to have the cylinder bored and sleeved. Took care of the noise. From what ive heard and read piston slap is not un heard of. Chevy gets lazy from time to time and the machining has alittle more play than usual. Some people live with it.... some people rebuild. It wont hurt if you live with it. It just bugsI have this 98 C1500 that knocks, I can hear it more at the botom near the flexplate and the oilpan.
It more audible when I start the truck but once it's warmed up you can bearly hear it. Rod knock maybe ?
Is it worth fixing this or just find a new engine ? It's got 190k miles.
