Best Answer

No. The harmonic balancer does exactly what it says. It is to keep the engine from viberating. You need to install a manual oil pressure gauge and run the engine cold and hot to determine if you really have a pressure problem. Most likely you have a bad oil pressure sending unit.

Can a bad harmonic balancer ruin your engine?

A bad balancer can cause failure for more than one reason. First, an unbalanced engine can have severe vibrations set up that will cause material failure in the engine, and it will break internal parts. Second, the balancer can come apart physically outside the engine. If this happens, the loose part can cause damage all over the engine room, and if caught in a belt or pully, jam the crankshaft. I've seen this happen!

A fuel rail pressure regulator could cause trouble.


Does fanning air brakes cause air pressure to increase?

No you lose air pressure .


Do harmonic balancers squeal when they are bad?

Yes they can squeal when the rubber to metal bond has been broken, the metal ring then moves over the rubber making a loud squeal. If that is the case it can sound much like a pending bearing failure on the alternator or water pump. This also means that your balancer can potentially fly apart at any moment and cause severe damage to the radiator or crankshaft sensor (if equipped). Also when the metal belt pulley does eventually slip off it will no longer be driving all the pulleys.


What is the purpose of a pressure cap?

A pressure cap is used to determine the pressure in your radiator. It raises the boiling point of the coolant. If the coolant boiled, it would cause gas bubbles to form and cause hot spots in the engine cooling chambers. The pressure valve has a spring set on a certain PSI (dependent upon the vehicle, I suppose) so that when/if the pressure in the radiator gets too high, the pressure is enough to force the valve temporarily out of the way, relieving the excess. Most modern cars have an expansion tank at the top of the system. The coolant, bypassed by the pressure cap, ends up temporarily in the plastic bottle and is then drawn back into the system as the engine cools.

If the harmonic balance is bad can you repair it or replace it?

I would contact the local parts store and replace the harmonic balancer if you think it is bad. a bad balancer can cause failure in the crankshaft bearings because of the shake.


What will a bad harmonic balancer cause?

It can cause a vibration at different RPMs. If it is wobbling around on the crankshaft it could cause damage to the crankshaft's snout. And a worst case scenario overtime a faulty balancer could break a crankshaft.


What would cause a harmonic balancer to shimmy on a 350 Chevy engine?

The balancer has a piece of rubber that holds it together, The balancer is made of two pieces with rubber in the middle, and the rubber is coming apart. REPLACE BALANCER. The Pulley that's bolted on the balancer may be bent or not on stright and flush on the balancer, That would make the balancer look like its wobbleing too.


If the rubber gasket on the harmonic balancer is ripped up will this cause a bad knocking noise How do you replace it if need be?

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.
