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'll sound like a hollow tapping sound while rotating.
Its kind of a grinding screeching metal on metal noise.
did you disassemble the engine to determine the rod condition? some harmonic balancers will make a knocking sound when they go bad
harmonic balance maybe bad
It will rumble and increase with speed.
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.
Yes if rubber isolator is bad
A bad cv joint/axle shaft on the front will make a clicking noise when turning.
A bad throw out bearing will make noise when the clutch pedal is pushed down.
If bearings go bad on a alternator/ will make a grindind noise or long squilling noise.. but if only electronic's inside alternator are damage no noise wil be heard
not always usally makes an noise close to a rattle or knocking hence harmonic.use a broom stick or hose to use as a listening device to locate the exact place of your noise could be starter sticking in(ect...)
