Someone ran a car out of oil and knocking happens, what would it be ? I am gonna take it apart and look at the rod bearing and the knockers and maybe the valves, I just thought you might have some more input as its a new engine still, but I was just curious about some ideas yall might have. Thanks

 

rod knock and probably a valve tap...the motor is shot...for the cost of a rebuild your better off just buying a new motor

 

yeah like he said...its problably the valve knocking
