Brief top end chatter on cold start
2006 IS350
The car runs very smooth but on cold starts after sitting over night or after an 8 hour work shift when starting i get a top end chatter/rattle. After 1-2 seconds its gone.
Anyone know the cause and resolution to the top end chatter on cold start?
Thanks

Just spoke with Lexus. The noise we hear is just the weights in the cam gears and it wont cause any danmge. The noise come from when the oil drips down through the cam gears and you start up your car just the weights moving without lubrication for a split second, until oil gets circulated into the gears. Will not danmage anything. When you get it fixed they just install a new part which helps keep the oil from slowly dripping out. To fix its about $250 + tax.
