Default LS460 knocking engine noise

We own an LS460 2008, when we received the recall notice that all the valve springs needed to be replaced, because they were braking, we were very concern that something else could be damaged in this process, because it was a mayor disassembly project and our fears came through. Soon after a knocking noise started coming from the rear of the engine right trough the fire wall and very noticeable inside the passenger compartment, even our Lexus independent specialist that services our Lexus cars for the last 14 years, says that from all the LS460 his company services, is the loudest of all. We have visited 2 times the original Lexus dealer we purchased from J. M. Lexus and Lexus of West Kendall for service in Florida; they all say all the LS460 have a noisy engine due to the 2 high pressure gas pumps and even the brand new 2012 would have the same noise. We took the time to test drive one with 500 miles in the odometer and of course did not have the knocking noise.
This is the most absurd answer response we ever heard. We have written 4 certified letters including the top Toyota representative Mr. Yoshimi Inaba Toyota Motor North America, Inc. Chairman and CEO, trying to get Toyota involved to do an inspection by one of their top engineers to trouble shoot this knocking noise that is causing it and they are ignoring our request since the beginning of the year. The original warranty is going to run out by the end of this year.
We welcome any similar comments from other LS460 or any other Lexus owners that are experiencing similar knocking engine noise.

EXACTLY how many MORE times are you planning on posting the SAME question, countless times, in multiple threads ? One might suggest as a new(er) member of Club Lexus, this might NOT be your best way to be introduced (to the group here). Of course, I might be wrong here .... but it is my humble opinion.

I would suggest letting them fix the service bulletin and take it from there. If your still under warrenty, it's their problem. Just my 2 cents

My car has no knocking and is quiet. Good luck
