Default Another LS1 engine noise question

Hey all, I tried searching but descriptions are so variable, and I couldnt find any videos with a similar noise.
Today I went to start my car and run it for a bit, its currently parked for the winter, and I managed to get a good video (attached) of the noise Ive been experiencing. Any input is greatly appreciated. It drives fine, runs strong, but this noise just doesnt sit well with me.
Its a 99 WS6 with 105,000 kms

Quit starting your stored car all winter. Not only does it serve no purpose, but all it does is cause harm. Put fuel and oil stabilizer in it and leave it alone, do not touch it again until youre ready to pull it out for spring.

Ive heard many opinions on this before. I dont do it every week or anything, but its been sitting since October 1, and it was a beautiful day out so I figured it wouldnt hurt to let it run for half an hour.
Either way, the noise is there whether Im using it daily or not. I tried to upload the video to YouTube but I keep getting a channel creator error message so itll probably have to wait until tomorrow.

finally got the video uploaded. Hopefully this can put my mind at ease. After running for a few minutes its quiet, no misfires, no SES. I have been told the early LS1s are quite noisy when cold, Im just trying to figure out whats normal noise and what isnt. Thanks!

Hello,
Pull one of your ecm fuses out and crank until you have oil pressure, then refuse and start it.
Sounds like bled down lifter noise. If you have clean-good oil not much else to worry about.
Hope that helps.

Thanks for the reply. But the noise started after running for about a minute. After a few minutes it went away, so in any experience Ive had a lifter should make noise right from start up. I was told it may be EGR or AIR related
