NO. A knocking noise in the engine is a problem in the engine.
A bad connecting rod bearing can do this
A bad harmonic balancer can cause a knocking noise. The harmonic balancer doesn't actually produce the noise, but it can cause the noise in the engine.
It can mean that the engine has a bad main bearing. Can also mean one of the pistons are bad.
Your transmission fluid might be low.
The knocking noise is commonly called spark knock. The knock can be called by the engine timing not being set correctly, or using gas that has too low of an octane for the engine.
A knocking noise can occur from worn engine mounts. When the rubber insert on the engine mounts are old and brittle the chassis is not protected from the weight of the engine. Creating loud vibrations that get louder as the vehicle goes faster.
Having a bad rod bearing could cause a truck to make a loud knocking noise and shake when driving at high speeds. The engine having a coolant leak or an engine timing problem could also cause the knocking noise.
it could be your valves or your engine
Noise coming from engine in Oldsmobile Cutlass could be as a result of an oil leak in the rear of your engine. This makes the gears to wear off leading to severe knocking noise.
can you elaborate? engine noise? stationary/moving? ticking, tapping or a definite knocking?
depends on what kind of knocking you mean. lots of engines can have what we call "piston slap" when the engine is cold and goes away in a few minutes when the engine warms up. If the noise stays and is worse when revved up you have a more serious problem.Hope this helps
many many things, Loose lug nuts which lets wheel make knocking noise. Engine will make a knocking noise if it is really low on oil. Some timing belts make a knocking, slapping noise just before they break.These are just a few examples . Have someone ride in car with you as you duplcate the noise and see if they can determine which part of the vehicle it is coming from.
Sorry, disregard this question, I didn't word it properly.
Cant you just ask the people at the car place?
Running too lean.
Replace the Harmonic balancer
it's probably a rod knocking
if its a low knocking noise it is normal on the 3.1 engine!! if it is loud check to make sure the valves are getting oil!! I have a 2000 Malibu v6 and it is the same way.
possibly distributor. tow to mechanic . if you drive , you could damage your engine.
Look into piston slap
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.
