I'm pretty sure if you need to change the pcv, you will need to remove the intake manifold.

Can someone point out where exactly the Pcv valve is or have a diagram that shows a location on a Lexus isf

The F has a pcv hose, from the valve cover to the intake manifold.

There's no pcv valve.

As Lou said, you may be able to locate it by tracing back the hose it this photo. If you don't have an A/O separator, it'll be connected directly to the intake where the host above it is.

The PCV valve attaches to the Separator Case

IS F pcv part # 12204-38020








12204 attaches to 12215

I stand corrected.

Thank you Joe.

Not sure why you would need to change it.

They can be checked however. Remove the PCV valve and shake it. If it rattles it is good. If it does not rattle it may be dirty with oil and other residues. Either way, if it is removed, soak it in some throttle body cleaner to remove the residues. Evaluate it again and if it works (rattles) re-install.

Or you can simply install a new one. I try not to throw away the OEM stuff since it is usually of pretty good quality. They are a pretty simple but effective device.

Would it be a good idea to change this before installing an aos? Is it doable without removing the intake manifold?

@Joe Z @illwillem can you verify the separator case is part# 12215-38020?
Most sites show a match for MY 2011 but some are showing not.
My valley plate repair is in-process, and after seeing the inside of illwillem's, I want to replace this part.

What purpose does the foam insert serve? Anyone happen to know the part number?

The foam is for noise reduction only, and there's still plenty of DI noise that gets through. I wouldn't bother replacing it unless it is chunking. Mine was fine at 180k miles+ when I did my valley plate. Not sure why you'd bother with replacing the separator case. If you're worried about it (I wasn't in the slightest), rinse it with solvent and call it a day. It's not that critical, and in service it stays exceptionally clean inside from a contamination perspective.
