So i thought i'd post in the general discussion since the Sienna has the 1MZ-FE w/ VVT-i Engine and that the Sienna forum doesn't have as many views compared to an area like here.
To start off, we have a 02 Sienna with the 1MZ-FE engine and at times, at around 2000 RPM [small range] it'll have a hint of a rattle. However if you have push in the throttle just enough and it maintains around that RPM with load [lets say on a hill], the engine will emit a slightly louder rattle.
I'm just curious if its anything to worry about or if its normal operation of the engine.
Thanks,
Tim
