2001 sonoma with 4.3. Just replaced intake manifold gaskets, water pump and took the starter out and put it back in.
Today I started it up and it made a god awful noise. My first thought was rod knock. From the examples I’ve seen rod knock is cyclical and constant. I ran it without the belt, but nothing changed.
Maybe a lifter? Starter alignment off?
The youtube link is bellow. Thanks for any help.
