I think the oil incidences for both of us are just a coincidence. Its a known issue with the Camshaft, I'd definitely take it to the dealer if you are still under warranty. As long as you have less then 70k miles then its covered. I was only getting the noise less then once a week or so (sometimes going a month or more with no noise)and sometimes it was barely audible but with 66k miles on my car I took it in and made sure I got it done while still under warranty since I've heard its expensive work if you're not.
One question to everyone. If the service envolves an oil change, and I'm running Mobil 1 Synthetic, is the dealer gonna know i have synthetic and replace it with Synthetic or are they just gonna throw regular oil in? I've heard its not good to switch back when you switch to synthetic, if this is true should I have an oil change done when I pick up the car and put the Mobil 1 back in it?

Like many others with this problem i too have had this issues esp during the winter, but this past winter i decided to switch to Royal Purple from Mobile one and i had ZERO cold start knocks. Wondering if anyone else had this success with RP?
I'm almost at 78k on the ODO, I get this noise intermittently and it started happening only in the past few months (after warranty period ended). I'm wondering what possible damage it could be causing the engine if I don't fix it? Assuming it gets worse over time. Any thoughts would be appreciated.

I had the same issue on mine. bought the car out of warranty @ 73k miles. after 4months started doing the starup rattle noise. tool it in the the lexus dealer it bought it from and fortunately got it fixed free. they told me the repair cost approximately 1500. i was told that it doesnt damage the motor long term yet i still remain skeptical. if you bought it from a lexus dealer out of warrantly and it still hasnt been 90 days since the purchase, they should cover at least 50% of the repair. its still sucks but is better than paying the full repair cost

I have a 2006 IS350, and have had the Cam Positioner TSB done (2 years ago) .... noise is occurring again now every few weeks. I don't believe there is any danger to the engine however it can be freaking embarrassing at its loudest....LOL .... a real treat when transporting friends who own BMW's or Audi's etc.
I don't believe Lexus actually has a fix .... i suspect that if all tolerances on the parts line up just right you have no problem .... it is a major fix and takes about 6 hours labor if i recall correctly.
I have reported it to the dealer again, and i expect them to deal with it at some point. They will likely fix it, even if out of warranty .... we're talking a design defect here, not a normal wear issue. Keep all receipts and make sure the sound you report is noted on your service receipts! I even made a sound byte .... i think that forced their hand the first time because the service manager at the time was a **** .... wouldn't acknowledge this issue, the brake pad issue, or the rear view mirror issue. New manager now... much better.

Mine was first serviced about 1.5yrs ago, but noise has come back again 
Anybody know the new part number that was updated in this TSB?
A pic of your invoice would be really helpful for those who brought theirs in within last couple of months.

^^ Thx Adio... will keep an eye out for it...
So the car is at the dealership...but they are saying "you are the only customer to have ever have brought the car back after the first fix"
.... This is of course followed up with "sorry we can't replicate the problem so no repairs can be done..."
Wish they would believe the countless posts in this thread that would say otherwise...
Any advice for what to say to them to get them to do it? Or should I just take it to another dealership?

i started hearing the knocking a couple of days ago after adding some seafoam into the oil. i checked the oil this morning and it reads just above the low mark.
need suggestions i am leaving town monday so i cant give the car to the dealer to figure out why its doing that but at the same time i am scared to drive it home 500miles.
as i see it i have two options
option 1
addf some oil in and hope for the best
option 2
go and see if the dealer can get the job done in oneday
