I love all your sounds.
Valve seals tend to smoke on startup and under long periods of idle.
This sounds like rings or turbo.
Check the shaft play....

If you often have to add oil between changes and don't have an oil leak then it very well could be bum rings. If you don't have to give it oil too much but still have visible oil smoke during normal operating temps then I would strongly suspect the oil seal on your turbine (hot side of the turbo). It usually fails with excessive shaft play and/or old age.

Very true. Replacing just the seal would be like placing a 'band aid' on a 3rd degree welding burn to the forearm. If you love your turbo, send it to MDC. I mean it!
now, back to our regularly scheduled troubleshooting session...
Form what sounds like it is your turbo, this is what you do. Turn your car on for exactly 1 minute, has to be cooled then started for 1 minute, get the Rpm's to about 2500, then turn off the car take the turbo off you should see oil on the hot side, I had a '90 Supra turbo with 155,000 and my ct-26 started going out, I thought it was my engine, saved a lot of time figuring out ti was the turbo. Good luck man!

a little side to side is ok...anymore than that and u have an issue
same thing was happening to me. I replaced the turbo and and all was well. But i'm not saying your problem is the turbo.... I checked shaft play first and it was horrendous. +2 check shaft play
