Engine whining noise
 

My B18B makes a whining noise, ever since I put her together.

I think its the alternator, since I put a metal bar on it and listened around the engine... it whines. Even moreso than a turbo's whine.... that is a little noisy.

So what can I do? Would squirting oil ALL over the alternator do any harm? I think I remember my teacher telling me that some electric motors/alternators are actually bathed in oil when manufactured...

Any ideaz?

Is it a loose alt belt?

Try tightening the belt back to factory spec.

If not that, it could be a blown bearing in the alt itself

If you alternator is whining its a sign to change it

Has the timing belt been changed? Timing belts whine excessively when they're old, i had this problem on my old motor.

KSR just did the belt, so I doubt that is the problem.

Like I said, I can tell the noise is coming from the alt since I put a metal bar on it and listened to sounds from all around the components of the engine.

I figure its a stuck bearing or some rust inside the alternator... I did buy the alternator from a wrecker (still under warrenty), but got it tested at Crappy Tire... it works... it made a tiny tiny bit of noise at crappy tire too. I figured it would get better with time. I want to douse it with oil, but then again, I want to douse alot of things in oil (lol)

Changing alternators is a bitch. The B18B in my 92 hatch has no space.

Last time I installed it, I had to try unbolting and prying the exhaust away... then I gave up and got a mechanic to do it... he did the same... any tips on how to fit this in?

Can it be done from the top if I move the power steering line? Or is it only doable from the bottom?

Thanks for your concer folks :)

To easily change the alternator just remove it and pull it through the bottom with the ls cv shaft removed it will come out is one hour.
