What does a knocking engine sound like? Whichis bad? The knocking from crappy gas or knocking that tells you a rebuild is needed. How to tell...

Can you tell I am in need of knowledge?

I want to know if I just need an adjustment or a rebuild.

 

need more info.
when driving/at idle/in gear

 

you need to locate where the sound is coming from? might just be the valve,trans gear,engine? buy a stethoscope and try to locate the sound.

 

i know sumtimes if ur low on oil ull get a knocking now if ur low and u add oil and the knocking goes away ur fine HOWEVER if u add oil and it still knocks then plan on spending sum money

 

try to put up a vid, nothing better than that

 

rod knock sounds like someone under the car hitting the back of the block with a hammer, but faster. bad fuel or timing knock sounds more like a light pinging noise when the engine is reved up or under a load. both are bad but the ladder of the two can be fixed alot cheaper.
