Timing chain rattle on startup

[dba]

Hi Everyone, new member.

I drive a 2007 Kluger Grande and for some time have had a momentary rattle on start up. Recently I split an oil hose and since having it fixed the rattle has gotten louder. It only lasts a second or two and then stops. If the engine is warm, there is no rattle. I have been told it could be the timing chain tension, the lifters, or the timing chain guides. All of those sound expensive. Has anyone else had a similar problem?

It could also be the VVT-i rattle which is very common. If you do a search you will find more info.

Thanks Trent, have been doing the research as you suggest and found a suggestion of increasing revs to 2000rpm before turning off engine. Will try it for a while to see how that goes.

I had the same rattle, had the vvti replaced under warranty, engine out job

I have the same problem with the rattling noise but it is happening more often after the car has sat for an hour or more. Has anyone fixed this? and how much did it cost out of warranty?

Before i left Toyota, the cost was around $450 per gear (you need 2) and i think it was around 12 hours labour. Yes, engine out to reach the rear vvti gear.
