There will be a loud knocking and rattling. The engine will not go far before it is destroyed. If in doubt chat the system has adequate oil pressure.
Is your oil level?
A Pockadacreek ( pronounced Pock - a - da - creak ) , is an name for an old - time vehicle from the early 20th century , that looks like a 1903- model Ford with a crank - like handle in front . It is called by the name , because of the rattling sound made by the engine . Today , the word is used to describe any type of old vehicle , that has a bad motor ( causing a rattling and kicking - like sound ) .
SQUEEEEEEeeeeeee! WAWK WAWK WAWK! also, they make a little rattling noise with their beak sometimes
An engine might sound like a diesel at operating temperature if the engine was a diesel or if there was an issue with the manifold. Sometimes gases escaping the manifold cover could cause the engine to sound different.
Because maybe something inside the engine did break loose. For example lifters, rods, pistons, exc. too many things to list that may have broken loose. You may need a new or used engine or rebuilt old engine.
Sounds more like a lack of oil or oil circulation problem. I hope you are not one that races the engine to hear how good it sounds. Flush the engine, change the oil and filter and never race a cold engine to warm it up. The rattling may be worn out lifters. Now pray. lol
It is the sound of the gears grinding against each other. Because it is at a high speed, it sounds like a rattling instead of a grinding.
The 2001 Chevy Cavalier may need a valve adjustment. Loud valves tend to create a clacking noise which could mimic popcorn popping.
It could sound very bad when it runs. It will sound like a grinding or rumbling or rattling sound when it runs. If it gets very bad it will seize, that is just lock up and quit turning. Dirt bikes have tough lives, and if they get mud or dust in them the bearings in the crank and big end on the rod will start to sound bad before they lock up completely. And you can hold your ear up to the engine when it is running, if there is a ticking or knocking sound coming from the cylinder then that is just the usual wore out piston noise, if there is a rumbling or rattling sound when it runs coming from the bottom of the engine that is the crank or rod bearning.
sounds like your valves are rattling check your oil
That is called pinging. It isn't a good thing as it can cause engine damage. There are a variety of possible reasons for it. You should get it looked at. For a short term fix, try going with a higher octane gas.
