CO-LS400

Dumb question from a DIY>. Where is the PCV valve on a 2000 Ls 400..

Its probably right in front of my face but I can't seem to locate it..
Thanks

Driver's side. It is the only thing on that V bank with a hose attached to it. You don't have to remove anything. Of this is off of an SC4, but I don't believe it's any different on LS4.

il check my dads 00 LS to make 100% sure for you. been meaning to do that anyway.

ntran, unless the SC4 was a vvt-i motor'd car then it could very easily be different.

what about the location of 98 LS PCV valve ? When are we suppose to change it? IS there any write up? I know there is a write up for the 1st gen. LS.

Do I have to change the grommet when changing the 1998 LS400 PCV valve ?

driver's side of the engine. Next to the oil cap. Just buy an OEM one and replace or clean up your old one with some carb cleaner.

I found it ! Thank you Grand LS4.

Today I changed the PCV on my `99 LS with 107K miles. Most likely it was the original one(i got the car with 38K miles). I was surprised that the old valve wasn`t much different in condition from the new part, no build up like on LexLS tutorial picture. The grommet was in a lot worse shape though, old rubber got brittle and i had to be extra careful not to drop anything inside the whole - the grommet broke into pieces as I was taking it out and I had to use both little long nose pliers and a screwdriver in the other hand to hold the breaking parts from dropping inside. The area around the valve was a little dirty - perhaps due to the grommet not being tight.
