Half moons should have been done and then any dirt/grime that falls on the cam lobes should be wiped off and then use a separate clean rag dipped in oil to wipe them so they are not dry when engine is started. Other than that pretty solid diy video.
I have a 06 Lexus 470 and has major oil leaks from old valve gasket. Thanks for the highly detailed video for tutorial that I will attempt to replicate.
Torque spec from Toyota manual is 53 inch lbs. The manual also says to install/torque bolts from the outside in, star pattern. Good video, I was looking for clarification on the spark plug tube seals.
Mine always, and mean always, come loose. I think the stupid rubber grommets on the bolts are the culprit. It also frequently leaks from the passenger side - its a constant battle with the damn thing.
Thank you for this vid, it was very helpful! Took me 4 hours to do the drivers side, but I’m a slow wrencher. My torque wrench doesn’t go low enough for this job, I spent way too much time second guessing if I had it too tight or not. Time to invest in another torque wrench.
Mines was leaking, I noticed all of my bolts looser then hand tight so I figured I'll just torque them all back to 53 in-pounds to by some time while waiting for all the new parts to come in. It hasn't been leaking again and I'm thinking Ill just wait till it starts leaking again before doing this repair. On a side note, it's been almost a year and it's still not leaking.
Bought complete kit, did driver side(was leaking even after retorquing), tightened up passenger side and hasn't leaked for the 4 years since! Still going to do the Passenger side when I decide to replace all my coils soon. Also, the SPT Seals being so old & dry may be vacuum leak points. It is the easy side on my 2006 Limited and would rather them all age more equally! At 103.5K currently.
Thanks for the vid. I just finished the job from watching this. My 03 V8 4runner is slightly different from the engine you worked on. The driver's side is pretty much the same but the passengers side has less room too work on. You definitely have to remove the air box and also unbolt the transmission fluid dipstick tube from the oil dipstick tube in order to access the cover bottom bolts. Actually it was more challenging than the driver's side IMO.
Purple cleaner is far better at removing the varnish on the valve covers. In addition, the half moons at the rear of the cylinder heads should’ve been removed, cleaned and new high temperature silicone applied.
Hey there JamesonDIY, I have the same problem with my 01 Tundra Limited with a leaky valve cover. They recommend OEM Toyota parts such as valve covers, spark plug gaskets and FIPG RTV Seal but I noticed you are using Aftermarket parts with Permatex Black RTV instead. How has it been coming along? Debating if I should Pay $240 for OEM parts to do the same job or go your route and save money. Let me know. Cheers
Thanks for this video I just finished mine. I noticed @ 20:28 you had the spark plugs gasket backward. Have you checked I see if oils leaking In the spark plug hole.
02:35 Wondering, since the cover bolts were loose, could you just torque them back to 53 inch/pounds and reseal the cover gasket? 13:50 It seems most people remove those half-moons and clean and apply the RTV.
The bolts get loose because the gasket compresses over time, becomes hard, and loses its elasticity. So the gaskets should be replaced. The plugs (half moons) can be pulled out and resealed if they are leaking
Hello I have a quick question hopefully you can help. I have a 2004 Toyota forerunner six cylinder 4.0 and I’m looking to change the valve cover gaskets. Do I need to remove the intake to do so? And if I do do I need to drain the radiator? Any help would be appreciated
i did driver side today aand i thought ii did eveyrhting correctly but white smoke started comingupfrom those bottom bolts and lots oil started leaking,..think maybe the gasket moved and didnt go on right? pinched or something like that? LS430 is a bit morefinnicky,.iwish it was as easy as thattoyota
For me The worst part of this job was removing the valve cover bolts 🔩. Because i felt 3 of them wore going to snap and i gently moved them back and forth to brake them free and after I spent 5-10 minutes on those 3 valve cover bolts I ended up snapping all 3 what a nightmare other than that easy job. I was thinking maybe the previous person might have stripped them on. Now I'm waiting to get the heads back from the machine shop. I had to do a valve job cause of a broken timing belt. Thank God I didn't deal with removing the broken bolts.
@transam8607 How did you end up getting the broken bolts out? I am half way through this job right now and have snapped off 7 of the bolts. Wish they were made of harder metal. Did you have to get your truck towed to a machine shop? I am considering hiring a mobile welder to come help weld some new nuts on to the 1/2 inch of bolt that is still sticking out and trying to remove them using that.
Is there supposed to be a snapping noise when you put the coils back in place? I put the coils back into my 4.3L sc430 and didn’t hear a snap. I haven’t started it so I don’t know if it will misfire.
Those valve covers are not cleaned too well and you should have pulled those half moons from the back and cleaned them up with new sealant on them. Just placing RTV on the surface will not seal a leak that will protrude from underneath the half moons. That is going to be a leak issue and the valve cover job will have to be done again.
To put it simply, this is not a good idea. To less or too much RTV in one area=uneven seal=leak. Putting RTV into the gasket groove in the valve cover itself , (in moderation) however, is a good way to hold a stubborn gasket in place during install.
@@oLOGICo99 hello thank you, yea I figured it out it's my pcv valve and that needed to be replaced on my 00 tundra, I couldn't pass the smog test lol Thank you!
Stopped watching after 7:30 when you bust the seal prying it out. You're supposed to bend those 4 tabs back and then the seals pop out in seconds and in one piece. How did you expect to put in the new ones? If you didn't know basic stuff like that from the getgo, I wasn't staying around for the rest.

That's probably the best quality video of a "how to" that I've ever seen!

Yeah I looked it up too. 53 inch pounds is the correct spec. Thanks
Yes! 120?? You will strip and possibly snap the bolt! 53!
Mine always, and mean always, come loose. I think the stupid rubber grommets on the bolts are the culprit. It also frequently leaks from the passenger side - its a constant battle with the damn thing.
After 9 long hours I finally finished 😅
This will save me about $400 bucks at the local garage. Thanks!
Super helpful! I was having some challenges with the spark plug tube seals and you showed me exactly how to do it. THANK YOU!
Badass perfect video, bout to do my 4runner tomorrow. One of the clearest vids i have ever seen TY!!

harbor freight has some cheaper ones that go down enough, needed this job done today so i picked one up, haven't had issues yet

The lesson here is: if you wait long enough, the bolts are really easy to remove.....
Awesome job. Great zoom in on area you are working in. Nice edits. Very nice presentation. 👌

Gr8 job👍👍👍 i wish if u could show up the RTV how u applied it on front side f valve cover the rear cover was clear. 👌👌👌
are you going to remove and reseal the half moons?

Good job my friend Fresno California
So it’s been a year had this just held up so far
I think it's backwards too..I am doing it for the first time on this engine, the OEM seals are shaped different which is causing the confusion
I not a mechanic but I put mine the other way so now I wonder and just follow the way I took out the old seal
Nice video thank you for the info will be using ur link
Awesome job and perfect quality,
thank you 👍
Mine didn’t have the bolt Rubber washers install them anyway??
The Manual states that the torque to the value cover bolts is 53 inch pounds.
Correct torque is 53 in. Lbs.
Should have pulled semi circle covers and put rtv around them.
Great video. How do you get the passenger side lower valve cover bolt out with the oil dip stick holders in the way???
Messed around with mine forever... I found a shorty ratcheting wrench at an advanced auto and it was super easy.

The oil seals had a metal tab u needed to bend up in order for the whole seal to be removed.
Exactly.
Also removing/replacing the half moons properly.
53 in/lbs, not 100+!
Still a good instructional other than those misses.
For the spark plug gaskets does it matter how to install them ? I think I installed them backwards oh man
From Toyota, do the bolts come with the grommets? Does each bolt need a grommet? If so, would that mean almost 40 grommets?
"Just give them a little douche." Best part of the video.
Thanks for this video I just finished mine. I noticed @ 20:28 you had the spark plugs gasket backward. Have you checked I see if oils leaking In the spark plug hole.
Is it correct at 12:17?
mikef058 no, at 7:04 prior to removing the old spark plug gasket it was correct.
They are definitely on backward.
@@Rochad_A every set I bought is that way he did it, the other way is not the way

The bolts get loose because the gasket compresses over time, becomes hard, and loses its elasticity. So the gaskets should be replaced. The plugs (half moons) can be pulled out and resealed if they are leaking
How’s it been running so far better?
Should have resealed the half moons on the back while he was In there. They are known to leak if your don’t reseal them.
Thank you great video

How long I've to wait to tight up after putting sealer
Don't wait, reinstall cover asap.
Brake cleaner. Thanks!
Thanks
Couldn't you run a bead of RTV around the entire valve cover area instead of only in certain spots?
To put it simply, this is not a good idea. To less or too much RTV in one area=uneven seal=leak. Putting RTV into the gasket groove in the valve cover itself , (in moderation) however, is a good way to hold a stubborn gasket in place during install.
torque 53in/lbs
Do you happen to know the function of the hose you removed at 2:05
thank you for the video helped alot
That may be the Pcv hose it is for my gs400
@@oLOGICo99 hello thank you, yea I figured it out it's my pcv valve and that needed to be replaced on my 00 tundra, I couldn't pass the smog test lol
Thank you!
That was hard to take off. The rubber seal was so brittle, it crumbled when I pulled pcv out.
@@chieflouie2821 I know same with me the grommet what very brittle it snapped when I pulled it and I had to use a screwdriver and mallet to pop it out
What about valve cover bolt tightening sequence?
Work from the inside out
Outside in, star pattern.
But inside out still would work.
Use full snug seat in pattern before final torque.
