if it sounds like the knocking is coming from the bottom of the engine i would bet it was the rods or rod bearings may be worn. if the knocking is on the top ,then i would have the lifters and or the rocker arms checked.

Knocking noise in the engine of your 82 Mazda 323 low compression poor idle anyone any idea what could be wrong?
knocking is probably a rocker but might be a rod, sounds like its time for a master rebuild kit First check if the motor pulley. Located at the lowest part of the engine, when the v-belt runs. check if this is not loose. For poor compression, check timing on the car an a possiblilty for new spark plugs
How do you tell which rocker tip is noisy on your el falcon?
While the engine is not running you measure the 'rocker gap' between rod and rocker with a 'feeler gauge' . Each engine has specs for this gap, and if it's too wide that's the noisy one.
How do you adjust the valves on a 1977 Chevy 350?
With the engine warmed up but turned off, remove the valve covers. Start the engine and loosen the rocker arm nuts until they make a knocking sound. Slowly tighten the rocker arm nuts until they stops knocking. Tighten it 1/4 to 1/2 of a turn past this point and they should be set. DO NOT OVER TIGHTEN THE NUT OR YOU WILL BEND A VALVE! Turn off the engine and replace valve covers. Check the oil once the engine is cool. You may modify an old pair of valve covers by cutting open the top, so you have a window through which to adjust the valves. It will still be messy, but it will reduce the amount of spilled oil. =================================================== What? You don't adjust your valves with the engine running! You move the crank with a wrench so the cylinder you're adjusting the valves on is at TDC (or the valve push rod is in the full down position), insert a .015 feeler gauge between the top of the valve and rocker arm. Tighten (rocker nut) until the clearance of the feeler is met but not so tight that you can't remove the feeler tool.
Loud knocking from rocker cover?
Could be a broken lifter or something along those lines. Will need to pull valve cover and visually inspect.
