knocking noise
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.

NO. A knocking noise in the engine is a problem in the engine.
Depends on where the noise is originating from, a suspension component, engine (top or bottom?), steering knocking when turning, going over bumps, etc. You need to provide more details before I can point you in the right direction.
Engine knocking can be caused by numerous things. Having the incorrect spark plugs, carbon deposits on the cylinder walls, and being low on engine oil may all cause a knocking sound.
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
if your engine is knocking that means you need oil. go get an oil change or add a quart asap or the engine will burn out
Detonation involves a supersonic exothermic. Knocking in a engine is spark-ignition internal combustion.
if the engine is knocking really loud you probably need to overhaul the entire engine or get a new or used engine because loud knocking is not good
When the fuel in an engine cylinder ignites prematurely or unevenly to cause power fluctuations and a "knocking" sound. usually occurs when an engine is very how or improperly timed.
