Default weird noise coming from nosedrive

Can anyone tell me what'* happening here? You can't here it very well, but it sounds like a bunch of stones in the */C. My car runs just fine, but it'* been heating up faster than normal...

Listening will tell you next to nothing. Remove the belt. Wiggle, shake, and spin. What do you FEEL?

Pulled the belt off. About 1/8" of play, but nothing out of the ordinary

In and out? Spinning? Wobbling? 1/8" play WHERE and HOW? There are a few different issues here.

What do you hear (describe the sound in great detail and the conditions you hear it).
Tell us EXACTLY where that play is, and what you're doing when you feel it.

Sorry I forgot to update this. I went back out and twisted it. It didn't move up, down, left, right. But when I twisted it back and forth it had a bit of play with it. about an 8th of an inch.
I'm gonna change my */C oil before I go back out just to be sure this isn't a heat issue.

And about the sound, I almost thought it was the harmonic balancer, but it only happens when it'* warm, so I eliminated that, it also didn't go away as I gained speed.

If it didn't go away as you accellerated, it isn't the HB or the coupler.

The coupler will make noise cold or hot. No difference. You need to describe the sound a bit better, and maybe consider investing in a $10 mechanic'* stethescope.

Changing the SC oil will make no difference in the sound.

If the coupler isn't rattling at idle, it'* not that bad yet.

A coupler'* noise will go away as rpm'* increase.

you know, I just went out and drove it for a few minutes, and you're right, it does go away when you get up to the high RPMs. This time, it started rattling from a cold start...

Just curious, but can I use an M90 coupler kit with my M62? I thought I read somewhere that they were the same

What'* a coupler kit? There is no kit. Just the coupler.

Get the INTENSE or ZZP coupler, get the oil and red goop from the dealer. Get the SC outlet gasket and yellow o-rings from anywhere you like.

You should also clean your TB and MAF, so get that gasket as well.

Fuel injector o-rings would be a really good idea also.
