In general it is the valve lifters if it has higher mileage. Is the sound comming from the valve cover (usually it is the part of the motor that has the manufacturer name on it). It also could be much worse, if you are not sure take it to an auto tech. Another item to check: Could be the grade (or brand) of fuel being used. Too low of an octane rating will produce a "knocking" sound when accelerating ... the burn temperature of the lower grade fuels is much higher than, say, 91 octane which ignites at a lower temperature.
No
NO it will not. If you have a knocking sound then you have trouble inside of the engine.
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.
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.
The first sign that your engine has thrown a rod is a knocking sound that comes from the engine when it runs. if you pay close attention, you will notice that the knocking sound is rhythmic and increases or decreases in accordance with the engine's revolution per minute (RPM).
Engine rod? Engine bearing?
Get it fixed.
Bad bearing or rod
Mine did the same, mine was a motor mount.
counterbalancer is bad
can you elaborate? engine noise? stationary/moving? ticking, tapping or a definite knocking?
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
