how much would it cost for dealer to clean up the carbon build up during regular maintenance? Anyone have paid for this service other than warranty and know how much? I recalled having dealer done it once many many years ago but under warranty, but ever since i don't feel i have any issue or i could be wrong.

I keep reading that the $600 service isn't much more than running Seafoam through the engine, but using a Toyota version of it. I believe that I read the tear-down walnut shell airblasting version (the real way to clean the engine) was in the thousands to have done.

You also need to intercept the other PCV line (the short one from the valve cover to the intake pipe), using a different catch can. This is so you don't mess with the amount of air that would bypass the throttlebody.
Srsly, lexus engineers, how the hell did you NOT see this coming, and then saying putting in new pistons would FIX the problem? Yea, right. You can't stop engine blowby, every single one of these engines should be recalled as lemons.

I've also heard the EGR system contributes to possible issues with buildup on the intake valves - is this correct? I just want PURE AIR being sucked into my engine --- how hard is that?

Yes, the EGR system will recirculate post combustion "soot" back into the intake, pre-valve. So it could also contribute to coke build up. Unfortunately, the EGR system actually helps increase fuel economy during low load operation (long term cruise) by displacing unnecessary O2 in the combustion cyl, which if there was an excess, would lead to leaner conditions and promote the production of NOx (smog). Removing it is also illegal, and you won't pass emissions with it bypassed.

rbipu,
Every motor is different and some will have more blow by than others. So to say that one catch can is the "best" is very suggestive. Unless you put in multiple cans in a series, you won't know if any single can is catching ALL the oil in the PCV hose. BUT, ANY oil caught is good IMO. It's a good idea to have a can on EVERY car IMO.
Just wanted to chime in and say this writeup helped me install a simple home depot can on my wife's 250. it is just temporary until I get a much better can and mount it up front.
Thanks to then OP for the pics and writeup.

They claim 98% of particulates filtered over 5 microns... page 7
I know I've seen videos of this testing, but cannot seem to find them at this point in time. The video showed them introducing a fluid into a pneumatic system via venturi, and with a filter further down line, removed all of the liquid.
