I would be interested in another update justflyin83. Do you regret getting the maintenance done or did the dealer resolve your issues after the so called fix was done. I too have an 06 IS350 with the same issue as everyone else on this tread. After reading all the posts to date I am still undecided as to whether this repair is worth it or not. I would still like to know from someone "in the know", if damage is being done to the engine when this rattling noise occurs. I can't imagine it's not, from the sound it makes. The randomness of it is very confusing. I cringe at the thought of my engine being opened up, I read the entire TSB, and it is a pretty invasive procedure. I agree, once you open up a factory built engine, it's never the same. I am going to monitor this thread for awhile before I take the plunge. I have 35000 mi. on my car, so I have plenty of warranty left, my only concern again is, am I doing damage to this engine or not. Rickaokc
