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.

What causes a loud knocking noise in the engine?
Usually, knocking indicates bad bearings on the crankshaft. You are going to have to budget for a rebuild on the bottom end of the engine. If the engine has extreme mileage, you would be better off with a remanufactured engine. your best bet is to get a used motor or if you have the money then buy a new one but either way they are kind of spendy. the cheapest motor i have found was used and priced at $500
