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.
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
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.
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
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
more than likely it is your exhaust pipe mounts that need replacing.
Detonation involves a supersonic exothermic. Knocking in a engine is spark-ignition internal combustion.
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.
When your engine has a knocking noise, it could mean that a rod has been thrown. It could also mean you are low on oil.
