Could not find a thread for this issue so I started this new one. Moderator, if there is a thread closely related to this same then move my post to the right place.

Wondering if the 278 engine noise is normal for my 2013 S550. It sounds like a very fast lifter noise that goes away after engine runs about 35 seconds and then I can hear what sounds like normal lifter noise and this sounds like half the frequency.

Is my engine starving oil pressure at valve lifters / rockers etc. at cold start causing this noise?

Just changed oil 2 days ago after noticing this noise. Oil is fresh and level at mark.
