I would also recommend the PCV valve change....using Genuine Toyota brand.
If you have the screw in type......I would STILL change it.
Also....give it a good look to see if it is clogged.
If it is....then you may end up needing to change the valve cover due to deposits built up between the baffle plate and the top of the vavle cover.
It is NOT likely that you have this condition....but it can happen....and the only good way to solve it is with a new valve cover.......that is if they have the same setup that they used on the 6 cylinder valve covers.
Having the engine breathing through the PCV valve and IN through the breather input....is CRITICAL to engine life....by avoiding the sludge/gell buildup that will result if you don't have that airflow.
If you like the Purolator filter.......I like the Bosch Distance Plus filter (same company) as it has a better pressure bypass valve, even better media than the P1 and a thicker metal for the can.
I have cut them both open and read river_rat's "from the bench" filter analysis.
The Mobil 1 5W-30 that others have recommended is a great oil.
VVT-i At least on the 1MZFE 6 cylinder, there is a screen filter in the oil flow path for the VVT actuators......which I found listed on the dealership parts list.....as being available.
So, if you come up with a VVT issue....that would be something that I would look into before replacing the phaser/actuator.
