Knocking motor I have a 02 ls1 and it has a nasty knock. It was low on oil so i drained the oil and pulled the valve covers and everything looked good. anyone know anything else i should look for before i have to pull the motor

can also be easy to confuse it with piston slap, does the noise accelerate as you higher the rpm's, and does it go away when she heats up. And you would be surprised how many ls1's tick and have nothing wrong with them
