Knocking sound from engine

Our database doesn't say to remove engine, but, it looks like you remove about everything else.

You should be able to use a long metal shank to listen at the valve covers and oil pan, where it sounds the loudest would be where I would look. You place the tip of metal shank on the valve covers/cam cover, whatever. The other end of the tool goes on that bone backside of ear, helps magnify the sound. Do the same thing at the crankcase.

Is your oil pressure ok?
