Had to get a new alternator and replaced the idler pulley as well. All good now.

Reported cause
Due to winter condition we up north are cursed with, I haven't been able to test to verify this cured it, but it was the only bearing that felt even remotely rough.

I've owned, road, and raced motorcycles all my life and can honestly say the last time any of my bikes saw a dealer's service department was 1985 and that was due to a warrantied dropped valve.

Yep, checked the pulleys when I had the alternator out...no whine previously so I'm hoping it's the belt direction like mentioned above.

This all started because I changed my motor mounts then proceeded to snap the oil filler tube.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Glad I got this resolved, it was a major pain but I did learn a lot in the process.
Had to take out the alternator, the belt off etc to get the tube in and after buttoning up everything today I have a whine under load? Alternator? Belt has to wear in? Need belt dressing? Thank you.
Update and solution...
Ended up driving the car to an alternator specialist and they diagnosed the issue in about 10 seconds after hearing the noise. According to the tech the alternator clutch pulley has a life expectancy of 60K miles and my car has 111K on it. The whine was very quiet at idle and got louder with higher rpm's. Alternator was original to the car.
I went home and pulled the alternator again, thankfully only took about 30 minutes this time, and brought it to the shop. My pulley would free spin and not "clutch" up when rotating in back and forth. It had zero resistance when spinning it. Not real sure what normal is. Not sure if it was on its way out or got goobered up during removal, but I now have a new alternator and I replaced the idler pulley as well. FYI the new Porsche idler pulley is plastic. Glad I got this resolved, it was a major pain but I did learn a lot in the process.
Thanks for the reply...looks like there is plenty of clearance between them. Almost sounds like alternator whine? Definitely wasn't there prior to my poking around back there.
Check the idler pulley you had to remove to take out the alternator. It could be that. You can use a long screwdriver as a make-shift stethoscope to listen to the pulley and alternator for bearing whine. Be very careful doing that with the engine running.
Did you install the alternator correctly?
Did you install the belt correctly?
This includes being sure it is installed to run in the same direction as it was before.
Did the belt have any sharp edges? This can be a sign the belt is not tracking correctly and this can be due to an accessory drive that has excessive bearing/shaft play.
I did NOT make sure it is going in the same direction. This very well might be the issue I guess? Should I turn it around and try it or pick up a new one? It is currently it great condition.
Thanks very much!!!
LOL. Ya know, there is a lot of truth in your statement.
This all started because I changed my motor mounts then proceeded to snap the oil filler tube.
. Story of my DIY life.
The belt rotation check is a good tip. However, all I can think about is all that advice in your alternator removal thread about hitting the thing hard with a hammer!
Did my oil filler tube recently. Everything worked fine for the first couple miles then the regulator went out on the alternator. With almost 80K on the car and 15 years I am guessing the alternator didn't like being banged around while getting it out.
Maybe just removing and re-installing caused it to act up?
Thanks AFX, ya, that's a possibility. My car has 111K, new for me at 108K, and I can't find anything in the maintenance records that shows the alternator being replaced. I do not want to do the job again so I hope putting a new belt on fixes the problem.
Definitely one approach
, however for what they charge, each coffee should come with a "happy ending".
Personally, while DIY can drive you crazy, to me it's also one of the joys. I like getting my hands dirty, understanding how things work and being as independent as possible. I've owned, road, and raced motorcycles all my life and can honestly say the last time any of my bikes saw a dealer's service department was 1985 and that was due to a warrantied dropped valve.
Well, threw on a new belt today and she is still whining. Did the screwdriver to the ear trick and it sounds like it is coming from the alternator. I guess messing with it made it unhappy. Charging fine, but definitely whining. Maybe the pulley on it is going out?
Mine was whining last year and I traced it to the alternator. I removed it this winter and had it rebuilt. Bearings were a little rough and the clutched pulley seized. Due to winter condition we up north are cursed with, I haven't been able to test to verify this cured it, but it was the only bearing that felt even remotely rough. Odd that it only appeared after you did the other work though, but worth looking into.
In all these checks there is one check missing.The alignment of the pullies .The the condition of their bearings has already been mentioned.
With the belt off, if you run a straight edge across the face of the pullies - are there any alignment gaps? If there are, the the misaligned belt causes torsion on the bearings which will cause wear and eventually this may be heard as a whine.
The idler pullies are inexpensive to replace.But fix the alignment issue otherwise you will be repeating the task soon. Don't forget to check from the a/c pulley all the way across to as many adjacent pullies that you can.
Good luck !
