PCV valve
So this 1994 ES300 that I aquired from dear ol Dad has gotten pretty much a complete overhaul. Doing some research and I'm wondering if I should change out the "pcv valve". I see through an online search that the actual valve and grommet isn't expensive however I would like to know if this is something that I can/should do myself? Also what would be the suggested BRAND I should go with. Any suggestions would be greatly appreciated. Thanks in advance.

From experience, you should buy the OEM one for $25 or less. Much higher quality than any of the aftermarket plastic garbage. Grommet, you can go aftermarket, they are all the same. Just realize that if your old grommet is brittle and hard, you will have to be careful as pieces may fall into the valve cover when you are trying to remove it, and you'll have to fish them out.

Thanks for the info. Just to be clear I should go to Lexus to get it? I was looking on.RockAuto. I just want to make sure that it's the right part and installed correctly since the car is about 23 years old with almost 200k .

...$10 on Amazon, free shipping. Get any grommet for it, I usually use whatever ships with my cart on RockAuto. Beck/Arnley, Airtex, ACDelco, Fram, w/e.
EDIT: I guess what I'm saying is find the grommet part number on RA, then search that up on Amazon and get it shipped free with the OEM PCV valve.

If it rattles, it will work. Blow through it one direction and see if it passes air, reverse and repeat and see if it blocks it. If so, good to go. This is not rocket science. Shoot some solvent through it and then re-install it. Unless it's original and been overheated and cooked brittle, this should not be an issue. A couple of bucks for a new one should run $2 to $5 most honest places.
On a '94 with 200k, I'd be way more concerend with:
a) replacing PS fluid
b) verifying AT service history and doing at least a drain/fill if not up to date (Castrol Transmax HM is $20/gallon at Autozone and a great fluid to use in these).
c) bleeding brakes and jacking/spinning/rocking each wheel to verify caliper, bearing, pad health, grasp and manipulate ball joints and TR ends.
d)check air filter and intake components.
e) verify coolant health, check all hoses for softness or bulging.
f) verifying timing belt service interval, and water pump and belt tensioner.
These things may have been done but make sure.
