In June I bought a completely green CARFAX 2000 RX300 and even have a printout from the local Lexus Service Dept showing it received every service throughout its life at the dealer. When my truck started smoking horribly when I start it first thing in the morning, I learned about the problem of engine sludge and excessive oil consumption in the Toyota/Lexus 3.0L V6. Thank God for the help of ClubLexus.com and the part number above. I visited the local dealer's service dept, called twice and emailed asking for an appointment and they kept saying they'd get back with me. Fortunately I found a Toyota mechanic on Craigslist to replace my rear valve cover and PCV and gaskets, etc. Mine has 107K so we also changed the Denso Iridium spark plugs. Anyway, now it runs marvelously! THANK YOU!!!
Oh, the red L-shaped PCV valve I got at the Lexus Parts Dept was the wrong one (it pushes down into place into the stock 2000 RX rear valve cover). So, I went back and got a silver and brass I-shaped screw in PCV valve for a 2004 RX330 that screws into the the reengineered valve cover.

Does anyone have a complete parts list with part numbers for everything needed to do this swap?
Thanks,
Steve

The hardest part is getting the bolt loosened up on the back side of the upper manifold plenum.
Follow the How To and you can't go wrong

I had the issue of excessive oil consumption. What worked for me was:
1. Replaced PCV valve and grommet.
2. Removed and thoroughly cleaned from front valve cover.
3. Check the two hoses for obstruction (there was none).
The oil consumption is normal now (after 10K), the baffles on the front valve cover may have been clogged or the PCV valve was bad, or both. I have the old style rear valve cover an never messed with it due to the pain of removing it. The PCV valve and cleaning the front valve cover is easy, I would recommend trying that first

You'll have heck of a time trying to put things back together if you do it according to that video. He's either done this several times before or he'll be troubleshooting poor performance for quite a while. Or may be looking through the video clip by clip. I'd strongly recommend taking pictures as well as bagging the nuts and bolts.... but that's just me.

So I strongly suggest that you try it on a long trip and have several bottles of oil on car. The worse thing about this RX300 is oil light never came up even I can't see any oil on my oil stick!! So check oil every 70-100 miles when you're on the long trip before it's too late.

Interesting this guy was able to get it off without removing the wipers....

This guy already removed the 2 "troubled" bolts on the back of plenum. So, it look so easy. He never touch the back of plenum for those bolts!! Lexmex suggest that can leave one bolt uninstalled; but not 2 bolts. I'm a little bit worry for leave both uninstalled, our plenum is metal(heavy) and tilt very much to rear, the bolts are there for a reason. But some guys still manage to remove these 2 bolts without removing the wiper and cowl cover and etc.... You can try your luck but I'm the unlucky one and end up took everything off in order to get it.

RX300's engine bay is shortest one, some Camry and Sienna are much easier.

No. it's not. Both are the support bracket bolts. The ground bolts can be accessed after you remove the plenum, just don't move the plenum too much(you could break the ground wire). See my attached file(I copy it from another forum), I circle those 2 bolts, the one at right-hand side is the most troubled one.

I will reluctantly do a coolant flush at the same time because we missed the 120k service according to Lexus. I'm dreading getting splashed by messy coolant in this cold weather than doing the valve cover/sparkplug change.
