People will tell you "it's so easy" to replace valve cover gaskets. Unfortunately, it's not that simple if you want to do it correctly. You can also easily screw stuff up if you cut corners or get too rough with coil pack plugs and injector plugs.
In this video I will show you how to properly replace valve cover (aka "cylinder head covers" in the FSM), spark plug grommets and VC bolt washers. I will also show you the proper torque sequence and torque value. This is for the 1UZFE VVTi engine, so please reference the FSM for your engine if it differs. If you have ANY oil on a spark plug or plugs, you need to do this job ASAP!

Thanks! Somebody please sponsor this guy!
Im not sure about GS400s but when I was changing my valve covers on my 98 LS400 I found out both the cam seals and the cam gears/vvti tube assembly were leaking. I also noticed a leak from the crank area which was both the crank seal and the oil pump after opening the motor up 😬. I know we share the same motor so stay safe out there my fellow GS400 owners and Godspeed.
Did this on my 03 GS430 over the weekend using this video. Thanks a ton for posting this. Turns out on one side, all the grommets for the plugs were broken. The car runs sooo much better now!
any leaks after? thinking of doing this on my ls430! kind of scared. is it hard to do?
im tryin to do this on my 03 gs430 as well lol
Quality Content Brotha....This is very educational and detailed. I love that you include Torque Specs also. 🤘🏿🤘🏿
Did my spark plugs today had oil and most of them really appreciate this video right now, going to need it in a few days.
Edit:: can't believe you liked this very cool not to many active channels around thanks for the good content and interaction!!
Hugely detailed and specific instructions. This video is going to be invaluable.
your videos keep getting better and better!
great video!
it`s also a good idea to check valve clearance once the covers are taken out
Great point.
What do you mean by valve clearance? What am I looking for?
This will be a good reference for me when I tackle this on my ls430.
how'd it go? I plan on doing it!
Back again my boy I finished the rear main seal and trans seal ima do the valve covers tomorrow or next day waiting on rock auto and motor mounts
Got a nice one 3.000 had cat delete today thermostat needs breaks park pin to release key front end ball joints and stuff
Thank you for this video I thew and broke my cover cause I couldn’t get the gasket out😂😂😂😂
Thanks for all those great, educational videos. I have a 2000 GS400 (144,215 miles) and keep it in pristine condition and when I got my car from Japan on 01/05/2000, I also bought the "shop manuals", which have helped me doing many jobs on it. At this time I need to replace the Oil Pan (bottom) gasket, so if you happen to have a video available, I will appreciate it if you can share it. Thanks again.
Nice car! If you’re talking about the engine oil pan gasket, sorry, I don’t have a video on that. It’s a fairly involved job and I believe the sub frame needs to be dropped down a bit. I do have a video on the transmission pan gasket.
Great work! I have all the same parts to replace, nice work on gasket grease on corners. Notorious leak spots as i here when parking on unlevel surfaces. Did you notice any engine improvement? Plugs were okay?
Thanks! Some plugs had oil on them which I discovered during a plug change. That led me to do the VC’s and grommets. Amazing how long these lasted, all things considered. 24 years old and who knows how many heat cycles?
Your GS, the content and the music are right and exact! Thanks for sharing!
Ohhhh boy is it tight in there, I just did this job last weekend and painted my valve covers while I was at it was a lot of fun it was a pain to get that drivers side cover on without scratching it, took me 45 minutes just for that.
Nice job 👍 won’t need to do that for a long time. Just curious though, are there any oil leaks elsewhere? It seems like the later UZ’s are a pretty leak-free engine. My 3UZ’s got over 300,000kms and still dry.
Thanks! So far so good!
The video I need the most explanation on and my man did it without talking 😭
Sorry about that! I try to minimize my yapping but sometimes I should probably talk. LMK if you have any questions.
Hey there man thanks for an other great video. I got my valve cover gaskets replaced today and was told that chemicals and what not needed to “burn off” my engine and that’s why white smoke comes from engine bay. How long should I expect the smoke to be around sir?
Thanks! Perhaps for a very short period of time you will have some oil burn off. It should not last longer than a few drives though.
Great video! Did you check to see if vvti cam seals are leaking. It’s a common issue in this engine with this age. I have the same engine. It’s a huge job.
I took a look and didn’t see an issue. VC gaskets were shot.
@@ForwardMomentum that’s awesome. That’s a lot of Money saved. Thanks!
Show usss some donuts !!!!!!
I like that Idea
Thanks for the vedio, nice work .
I did it my self in my ls400 1uzfe non vvti . Exactly 💯 % same work .
But you put a sealing selcon 🤔?
Not need for this amount of sealing selcon , if its to much mabye it case oil leak .
Its better to remove all half moons from each side , clean them , and clean under them , and put sealing selcon under them and above them , and little in the corners, to avoid any oil leak in the future .
And just put a little, very little amount of sealing selcon ( Simple smear),, and only head valve cover Gasket it self will prevents any oil leak , without any sealing selcon.
Wouldn’t be a 1uz if it didn’t need valve cover gasket’s
yes tryed a wooble socket and extention but did not help,thats why I I'm thinking of the moter mounts,whats your thought
I don’t know, the mounts are a HUGE pain. That’s a huge move for a simple item.
I’m gonna cry :( I did this to my gs last month and was stressing because there was no videos on my exact engine. I now have a check engine light and my trac control won’t turn back on lol.
Scan the DTC and let me know what it is.
Didn’t need to move tranny dipstick or loosen the bolt? Only taking off the oil dipstick?
I don’t have that any longer since I did my manual swap. You may want/need to do that.
Finally did my valve covers any tips on driver side to make it a little easier fit folded the gasket and going to have to retry not sure what I was doing wrong but I could not get it to set to save my life
All I can say is keep trying. Passenger side is actually harder, so if you got that side, you’ll definitely get the driver’s side eventually. Usually it’s the spark plug grommets holding things up. Make sure they’re oiled a little.
@@ForwardMomentum I'll definitely try that, passenger side for me went flawless definitely was the easiest side room wise for me. This time I'll try it during the day when I got some light to work with may help aswell.
Btw I’m pretty sure u installed new spark tube seals backwards
Nope. 100% correct. Frankly, I was worried myself and quadruple checked it.
just did my valve cover on drivers side but having trouble with one bolt #2 but unable to tieghten it,no room for any socket or wrench,I have tryed everything.would you sugest lossening the moter mounts and raising the engine in order to get to that screw, besides I cant figue how you used a tough wrench.
I didn’t have any issues. Have you tried a wobble socket and an extension? That should do it.
@@ForwardMomentum
01 gs300 my radio and a/c panel turned off any idea?
Much simpler on the 2JZ haha
so for the bolts your doing 75 ibs with the torque wrench? whats the in??
I’m confused by your question. In the vid it states “75in-lbs” and in the title of the vid is the type of car. What am I missing about your question?
@@ForwardMomentum I was confused by 75 in/pounds, never used a torque wrench before. but i figured out, about 6 pounds of torque😂sorry
Oh no problem at all. I was just confused because I thought I answered those questions. Yes, a very small setting to get those torqued up. 👍
What year is your Lexus?
98
Screw that lol
