Customer Question

I have a 2007 rx350 with 82k miles that has a rattle at start up. I thought timing chain tensioner. But as I'm reading more posts people are saying vvti gears. What has your experience found in these cases
JA: Where exactly do you think the noise is coming from? And how long has this been going on?
Customer: Front top of motor and maybe 5-6 months.
JA: What is the model of your '07 Lexus?
Customer: Rx350
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Probably not. And nothing as my first thoughts were timing tensioner and knew it would go awhile like that. But now not so sure.
JA: Anything else you think the mechanic should know?
Customer: Nope.

Can you possibly get a recording of this rattling noise on initial start up so that I can hear it?
