How To Replace Valve Cover Gaskets 1998-2000 Lexus LS 400

This how to video shows the procedure for replacing the valve cover gaskets on the 1998-2000 Lexus LS400 with the 1UZFE 4.0L DOHC V8 engine with VVT-i intake. It shows the tools, parts and part numbers, and gives an overview of the repair process.
I also show how to replace the spark plugs, and replace the PCV valve and rubber grommet on the driver side of the engine.

This is a Great Detailed Video. I like the coil trick because I broke most of mine - even after i oiled the connectors and let them sit for hours. I'll be on the look out for a PVC valve grommet. Oven Cleaner is cheap and will cut that valve cover cleaning time by more than half. I have to do this to my 1999. I just did Delphi Coils and NGK Iridium Plugs. Thank you for your help. Now I know what to look forward to.

[@nourestani]

[@cashtr3245]

can you post the links to all the parts you got? i can’t seem to find the little o gaskets

[@DrCh0ngo]

Great video. I’m planning to do mine this summer. Can you post a breakdowns of the costs for the items? I’m assuming you got them from a dealership? Are all the parts OEM?

[@generationhighoutput]

I bought OEM Lexus/Toyota parts on eBay. The spark plugs, valve cover gaskets, grommets, PCV valve and hose, and FIPG gasket maker was about $200 total in parts.

[@Parkertip]

Awesome video!! How is the car doing?

[@generationhighoutput]

It's running great! 250k miles and going strong!

[@edgartuttle215]

Where did you get the long swiveling socket thing?

[@generationhighoutput]

It is the 3/8-in Drive T-Bar with Flexible Ratchet from Harbor Freight Tools.

[@Yash-jo8hv]

Is this the same for the 1993 Lexus sc400

[@generationhighoutput]

The procedure is basically the same. The 1998-2000 LS400 has a different intake manifold, but it is the same engine.

[@44altecz]

Make sure you buy new valve cover gasket bolts they’re cheap and it should be replaced as well

[@bigboy1111hater]

Where did you get pcv hose I can’t find it anywhere

[@generationhighoutput]

Try searching online for "Toyota 12261-50040" and hopefully you can find one for sale.

[@bigboy1111hater]

@@generationhighoutput contacted Lexus and got it thank you though!

[@maslyata]

How come you didn’t replace those half moon things?

[@maslyata]

Never mind, i just did my and see that they are metal ?!? Looks like they can come out tho

[@generationhighoutput]

A LOT of threads on ClubLexus and other forums talked about replacing them. Mine had no signs of leakage, so I saw no reason to mess with it. If it's not broke, don't fix it.

[@Babyboy-wm1bp]

That's what the gasket maker is for. To fill in the gaps

[@ninosuavecito9168]

I trusted this guy til he broke a bolt that only needed 5ftlb torque

[@generationhighoutput]

I am not a professional mechanic, I make mistakes. I left it in the edit to hopefully help others avoid the same.

[@Babyboy-wm1bp]

52 inch pounds is the correct torque specs. I bet you he just went ahead and drove the damn thing.

[@Babyboy-wm1bp]

The video is not great, you showed nothing about taking the half moons out or putting them in. There is a certain torque spec and order you tighten the bolts down to for the valvue cover.

[@generationhighoutput]

I did not change the half moons at all. They looked fine to me.

[@KhiJ2016]

Ay bro theres this thing called engine cleaner or carb cleaner...its just alumi...old gift card wtf??.😂😂

[@generationhighoutput]

An old plastic gift card is great for scraping built on gunk and won't damage the aluminum.

[@KhiJ2016]

@@generationhighoutput ye if u like scraping shit or an hour...why do that??when u can just dip the pan in degreaser for that same hour and just spray it off Work smarter not harder..

[@jimmyelmes6828]

Whoever said that is a complainer either way it still got done and prolly came out the same and ye idk what their tambour if you wanna scrape it what're you gonna use a reason blade or a putty knife or driver and scratch dafuq out of the valve cover but thank you very helpful video
