Squealing and smoking

Greeting,

I had to run today just a downpipe and 2 foot straight through pipe until I get my new exhaust.

I didn't run it hard or anything but when I got into my driveway, at idle, I hear a squealing sound from under the hood.

When I opened my hood, there was some smoke. I don't know if the smoke was burnoff from the new pipe (I hadn't see any earlier today).

I can rev the motor slightly and the turbo seems to spool okay and the squealing goes away. Pushing the clutch seems to have some affect on making the squeaking going away or coming back in.

Any ideas?

Update. It seems like it transmission related. Lime thw throwout bearing has gone bad. Most of the squealing comes from pushing the clutch. Not like it's a squeak from the pedal but from something inside the transmission.

I don't know what would cause the smoke though.

I'm stumped.

Check for a locked pully

I would think the smoke is from the short exhaust. Probably hot exhaust gas burning old oil and road grime off the frame.

Both good things to look for. The pulley idea is a good one to check but the noise gets worse as I engage the clutch.

I may have 2 things going on. Short exhaust burning stuff and clutch/transmission issues.

Any one else have their 2 cents?

Thanks again everyone.

FYI.

I peeked my head under my truck this morning and this was sticking out of the lower bell housing vent. It looks like something that the transmission shouldn't be spiting out.

For those of you that were kind enough to answer, here is the final prognosis.

Also, unrelated, the ZF is a monster.

Yeah. I left this one to the pros. My good friend runs a reputable shop so it's all his for the next few days. Last thing I want to do is pull that transmission in my driveway. A toyota trans, maybe, but not that monster.
