Want this question answered?
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 shouldn't make noise. If it does, replace it!
Replace the Harmonic balancer
Hard to say. However, if the "rubber gasket" you're talking about is the center bushing on your harmonic balancer, that could throw your Harmonic balancer out of balance. This could easily make it shake to beat the band which in turn could be the knocking noise you're hearing. I suggest you get it looked at immediatly. If that is what happened, your engine won't survive long.
Most likely the noise is made by the power supply or a failing hard drive.
it'll sound like a hollow tapping sound while rotating.
== == I do believe if you hear a knocking noise that your crank shaft could be failing. Which means you will need a new engine. Have it checked out. Replace the harmonic balancer they will make a bad knocking noise. When you start it and the oil light goes out and it knocks, this is what is wrong with it.
The balancer is made of 2 pieces That have a rubber piece in the center of them that hold the balancer together. If the balancer comes apart YES it will knock / make noise and the engine would vibrate/shake. You would be able to move 1 piece of the balancer with your hand if that was the case. Check it.
Whining noise near belts had pulleys adjusted any idea what is causing this
A whining noise in the transmission is usually an indication the transmission fluid is low. Check the transmission fluid and fill it to the recommended level.
Harmonic Balancer needs to be replaced on the front of the crankshaft. Use a screwdriver as a listening device. Put it on the oil pan and listen for noise. This is only if you determine balancer not the trouble. If you here noise from oil pan most likely rod bearing problem. You just received two engine evaluations that would have cost you at least $100 dollars. Good Luck
A loud whining noise, excessive oil consumption, loss of power, and a vehicle that smokes can be symptoms of a failing turbo. Also, a failed turbo sometimes leaks oil that can be seen on the body of the turbo, and a failing turbo many times deposits oil on the piping that leads to the throttle body.
