quote=Buck Rusty "... We had the oil changed at Toyota before we left town but it is still doing it, occurring if the car hasn't been started for close to an hour. I mentioned it to the service guys and got them to listen to it(surprisingly it actually did it in front of one after it had been sitting a bit.... this particular guy said he thought it was normal.. it bothers my wife to hear it all of a sudden now when the engine started so nice and quiet for the past two years?..."
It is tough to diagnose your noise without hearing it. Maybe you could attempt to record a video like this one Friendly_Jacek posted a while back. While you are on that thread, read up what Ferretwoman had to say, she and F_Jacek had some good dialogue:

You probably need to reference the last 4 or 5 digits of the VIN to get the sequence of production, or have a dealer look it up. It IS confusing. One thing for sure, if my engine had that 'diesel sounding' clatter on that video (heard at cold start at 22 seconds), I'd be researching the most reliable dealer shop I could find to fix it while you have the warranty. (Mine has the sound of a normal start at about 48 seconds.)
BTW, how many miles you have and what weight/type oil using?
Good luck and read up as much as you can on this issue, it has some traction on the 4.4 gen RAVs also. The 2AR has become Toyota's prime most reliable engine, still in use in today's RAVs and Camrys, but some may
have this flaw...The value of this forum is to try to separate normal noise from a problem, and judge was you can live with. Good luck, let us know how you fare.
