Belt & pulley squeak n55

Replaced my Serpentine belt, tensioner and idler pulley at 55k Miles. Car now has 59,8xx and will make the exact same squeaky noise it was making before. Instead of a constant noise like previously, it will make the noise after a decently long drive (10-20 miles) but will be gone the next morning. On short drives where it does reach operating temperature there is still no noise. What could it be?

Didn't find anything else on here with hearing the noise AFTER everything was replaced.

Thank you in advance!

Could be the alternator. Not belt-related, but have you replaced the water pump yet? Not a usual source, and a bit early, but possible. A mechanic's stethoscope is your friend here.

Have replaced both thermostat and water pump. How can I check to see if it's my alternator?

BUMP. Can anyone help me out? Kinda nervous to drive my car and have yet to find any information on it. Sprayed water onto ribbed side of belt and noise did not stop. My next assumption is that it is a pulley. I replaced tensioner and idler pulley. What other pulleys go bad around 60k Miles?

Like I said, you need a stethoscope. If you don't have one, take a wooden broom handle and stick one end on the alternator body and the other on your ear. If it's the alternator, you'll hear the same tone. If not, move around until you find it. Watch out for spinning things.

Did you fix this? I was chasing a squeek and finally got it. It was the PCV valve built into the valve cover. It takes about 3 hours to swap it and can find for about $100 on ebay. This was on my N55. It's so nice having it quiet.

It also addressed a slightly soft brake pedal, it's firm as can be now.
Also I have a DCT and coming to a stop, I'd be stationary and the rpms would slowly go from 1500 - 750. Now it's at 650 rpm before I stop and the engine runs super smooth and no more hiccups, hesitations. It's shocking the difference the valve cover can have.
