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.
