I recommend having the rear spark plugs replaced while the intake manifold is off depending on how many miles are on them. Otherwise it's a pain to change them.
I wouldn't put the cover on top of the engine when prying off the old gasket, because it can be brittle and the pieces will fall into that engine compartment and you cannot get those pieces out. Do the prying on a covered floor.
This is a “600” dollar job where I’m from..I have my gaskets. Here we go 💪🏼
TWO YEARS LATER: How did you go with those gaskets? I'm trying to do mine now but might have to do the head gasket as well, which means removing the cams and timing belt.
I have only one complaint. never ever use metal tools to remove the gaskets, use wood or plastic as a metal tipped tool can gouge the metal and create a small channel that oil can leak from or create microscopic burs that can damage the gasket from vibration over time. If you need leverage they sell hardened plastic tipped metal tools for this exact purpose.
Dang thanks for letting us know , that makes since , I’ve been messing up
😊😊😊😊
Terrific vid mate. It amazes me how you guys keep yours head together when doing complex process tasks like this; getting the vacuum hoses back in the right place, not forgetting harness connectors etc. What I don't understand (and nobody talks about it so I assume everyone else knows) is how you organise your nuts and bolts so they go back in the right place. That's the nightmare. Having 3 left over at the end.
kudos.
Thanks. I usually put bolts and nuts right back where they came from when I remove a part if possible. That way I don’t lose them and I remember where they go for the most part. Sometimes you can’t do that so in that case, I will separate those fasteners in their own piles next to the part I take off so I know that they belong to that certain part.
Sticky tape with labels or numbers
Do a bunch of this and most of the stuff goes back together like a puzzle. To an extent. Toyota makes it easy cause the electrical connectors are almost always different to any nearby connector. But I'm Def watching this video to reference a job in currently doing
front one easy, back one nightmare!
Not really
Party in the front and business in the back.😀
Just did this yesterday and it’s not that difficult if you have small hands, just be careful and see by feel
It's not that bad, Just take your time, I disconnected less as possible with the throttle body and a few other shortcuts.
How long should this take a qualified mechanic to do both valve covers, seals, spark plugs and ignition wires? Was quoted somewhere between 6-8 hours for my 98 es just want to make sure it is in line
You're a good man for sharing this experience. Thanks!
No problem
Hey man I just want to thank you so much for this video.. I been at it two days trying to move that wiring harness 🙏🏾🙏🏾🙏🏾
Thanks for your video, this helped me with my rx330. The gasket looked fine it was clear oil was spitting out over on the side with the half moon.
Nice work!
Great video that helped do the job much easier! Thank You
Great video it helped me replace the valve cover gasket in my 2000 Lexus rx300.
I replaced it on my ES300 with minor challenges and got it done, but I have to ask how in this world did u get that 14mm loose from the back of that plenum? From the top or did u unscrew it from under the truck? I bought a nano socket & wrench......nothing i have fits.
Just in case you're wondering.....yes, I've removed the windshield wiper compartment and still can't get nothing in there
I honestly cannot remember. It was probably an offset 14mm box end wrench. That’s my go to for small areas
Lol I believe you. I probably reached around in some awkward position just to break it free as well.
that battery corrosion tho! great video great explanation
You’re a life saver ! Thanks bro
Doing valve steam seals and following along to gain access. Excellent video
Are you pulling the cylinder heads? You can’t do valve stem seals from the top UNLESS you are risky.
EXACTLY!! The type video I was looking for thanks bro!
Very good video my brother now I can doing myself tank you very much.
You’re welcome
verry good vedeo ,we learn alot from you guy. thanks alot.
No problem
Thanks for a very informative video. I wasn't confident to attempt it myself, so I was seeing what the repair shop would have to do and also what questions to ask about the job. Thanks again.
You’re welcome. Let me know if you have any questions and I will try to help.
hello i love your channel.. i have taken on the task to replace the bypass coolant hose.. so now i have the gaskets and im stuck on where to place the two water inlet and out let gaskets..looks like the intake manifold gasket takes care of those two gaskets... do i put the water inlet and outlet gaskets under or over the intake manifold gaket?
great video bro
Mine is 18 years old. It had a valve cover replacement about 10 years ago. Now it looks like it needs it again. Oil all over the front as you mentioned. I'm having to add about a half quart a month.
You’re not adding a half a quart a month from gaskets..check rear main seal, oil pressure sensor, and oil pan integrity
The spark plug seals are upside down just done this exact engine today.other then that all looked good
Very helpful thank u.
No problem
Tip I find a impact drill more useful for the those 2 Philip screws under the throttle body then a screw driver the screwdriver will just strip the bolts
Thank you!
Excellent job!
This is great! How much did you buy gasket valve cover?
About $30-35
My 96 Avalon looks exactly the same, might have to do the timing belt too. Wish me luck, this looks easier than the timing 😂
Great video!! Love the mockingbird singing also lol
Very good video brother tanks
No problem
Do you have to drain the oil before starting to replace the front side of the valve cover ?
No. Sorry for the delay.
Thanks for the video. This is, by far, the best video about doing these gaskets.
Thanks.
Excellent video - especially like that you don't disconnect the coolant and breather hoses from the throttle body - these inevitably leak if disconnected on a 20+ year old car. Remove as little as possible!
Your video shows the injector harness being set aside to the left and the vacuum manifold assembly over to the right. Are you certain this step is required? The 1999 Camry V6 Toyota repair manual says that you only disconnect everything from the plenum and the plenum should lift off.
Is it possible in your view to not disconnect the injector assembly and vacuum manifold and set them aside in order to remove just the plenum?
Priya Jakatdar Not sure. That’s why I said I haven’t done these in awhile. It’s a guide, not everyone will do it the same way. I will say that if I feel it is easier for me to move something to gain better access to something else, I will do that.
@@HelpingHandAutoRepair That makes sense - thanks. Did you reuse or replace the plenum and throttle body gaskets?
Priya Jakatdar reused them. No issues there unless they are are damaged completely.
@@HelpingHandAutoRepair Yes, makes sense and thanks for your quick reply. I assume you didn't replace the plugs and wires while you had everything disconnected for the same reason: don't fix what's not broken?
Priya Jakatdar By all means replace the plugs and wires while you’re here IF they are needed. I was specifically instructed to change the valve cover gaskets ONLY on this car which is a customer’s car. They were selling it so I do as I was told. They wanted to spend the minimum amount of money on it to just stop the leaking.
Hands down excellent MF VIDEO probably didn't have to disconnect the throttle cable idk 100% but to find out lol but nobody else can do explain this job any clearer than what you did THANK YOU 👏👏👏👏👏👏👏👏👏
Thanks! Appreciate you.
Should something like brake cleaner be used to wipe down the areas the RTV is being applied to? Seems that would remove more oil residue than a dry wipedown.
Whatever you want to use is fine
Nice job.
I just changed engine oil, do i have to drain engine oil to replace valve cover i have 04 Camry v6
No
Grease the inside of spark plug tube seals first then the valve cover will lay right down perfectly without having to mess with em
I have a 2002 camry solara sle and I need to change the same valve cover gaskets. I ordered from advanced auto part however the O-rings gaskets were too big, could list the part number for your gasket kit and where you got the them from?
Got them from Oreilly Auto parts. I believe the number is VS50471R
@@HelpingHandAutoRepair thanks for replying!
I have that engine and want to do the rear valve cover gasket...since it's so hard to get back there what parts should i replace while im there,i know spark plugs is one...
BIG DRU plugs and wires.
@Tupac Shakur the pcv valve is stupid hard to get out for a pcv valve too!
Yes the pcv will break apart once you remove it. If you have the rear cover off then it no issue as you just remove the broken grommet and valve. I tried to replace mine and half of it became lodged inside the cover. 97 Camry 3.0 V6
@@77Joseph777 same here. I had to pick out the peices with a pair of needlenose plyers.
Joe 07
Tweezers and a clothes hanger,Hopefully you can get those 2 philips heads and throttle off but if not just unhook the hose next to the throttle that plugs into the passenger side of the intake,Remove the diagnostic plug (if you have that year) and move that tiny black ground wire.Now make sure you dont drop the tweezers.PS use a small short thin or better yet a preferred long narrow type flathead too break the grommet so you can have an easier time.Any sludge that gets disturbed just pull out with your finger digging your finger against the wall on the passenger side of the hole.
You forgot to remove the half shape on the right and put silicone..good diy
The job takes extreme patience.
Hey there, I just found out today after inspecting the vehicle, an 06 toyota highlander, that the front Valve cover gasket is leaking.
The back one seems to be ok via a visual inspection but i can only see so much. Would you advise changing both covers, or is it ok if i change only the front cover and then wait for a period of time to see if there is still some leaking?
Valve cover gaskets normally come in sets. Replace both. I’m sure the rear one is leaking now or just about to start leaking.

@@HelpingHandAutoRepair Thank you for the prompt Response.
Of course.
Of course.
Hello . basically . I was changing a sparkplug of a V 6 Rx 300 0f '01. the sleeve of sparkplug at the back ,broke off where the hard palstic , about 1/2 inch. I have the sparkplug out . I did everything possible to pull it out . after lubricaring with silicon , it doesn't even turn . I was thinking of drilling it to pieces, and after that , vacuum inside . will it work? Thanks.
I can’t advise on this. I have had this happen to me before and it was an absolute nightmare. Just get it out however you can.
When removing the passenger side bracket on the intake manifold (14m & 10m) did you see a bolt sticking out of the firewall? It's directly in the way of both nuts.
If I recall I think I mentioned there being a 10mm but or bolt in the video. It is holding a power steering line bracket I believe.
14mm bolt should be what’s holding on the intake manifold bracket.
Right, I confirm seeing both of those. But, in addition to those, there was a bolt sticking out from the firewall with the head being on the other side and sticks out right in front of the 10 and 14.
This was in a junkyard, I was trying to pull the harness for a project. I am just unsure if all models have that bolt as it seems what I saw doesn't match everyone's description. It blocks access to the 10 and 14.
Also want to say thank you for your reply and time. Pretty awesome when a content creator (like yourself) makes time to interact with thier audience. Great video and work! Take care.
How long should this job take? I have a Lexus ES330 (camry) and I was charged 4.5 hours to install a valve cover gasket kit. I was told the back one took most of the time. Thanks.
The back one does take the most time. 4.5 hours book time is probably right. An experienced person could probably get done in 3.5
@@HelpingHandAutoRepair Thanks very much
I believe you installed those spark plug seals upside down. Fel Pro seals should be seated differently than OEM ones
I think your right, I did put them wrong like him
Yeah they are upside down. I also just did the same thing. Fel-pro has a video explaining how to install gasket correctly.
are those tube seals in upsidedown ?
gracias , me acaban de pasar un lexus 98 se300 pero tiraba aceite y lequitamos y cambiamos los gasket, hoy checaremos como quedo, espero que ya no tire aciete la verdad.
hoy solo queda el cambio de aceite despes de tres dias jajaja
What is wrong?
How do you get to the exhaust manifold in the rear of the engine? Do you have to remove the upper intake manifold and rotate the engine or something? I believe my exhaust manifold gasket is leaking
You should be able to get to with a combination of the top and under the car. It’s probably best to remove the bottom of the exhaust first and then get it it.
What type of silicone did you use and how much do you torque the bolts to? Did you use the same bolts ?
Black RTV silicone.
Same bolts. I would have to try and find the torque specs again.
Same bolts, 72 in/lbs.
Thanks
Do you have to replace the spark plug tubes? when replacing valve cover gaskets.
They usually come with the valve cover gaskets. You are already there, might as well.
My car has 104k should i also replace spark plugs & coils, don’t see nothing wrong with them
I would since you’re there already. Unless you know you had them replaced prior.
I heard that it was necessary to add washers to the bolts before reinstalling?
Same here I’m trying to make sure if I need them or not!
@@Champ0204 i used 2 5/16 washers on each bolt, no leaks so far. Toyota recommends replacing the bolts, 2 washers works well.
I used 1 washer per bolt, Some replace the bolts but all you need to do is add a washer and that works great, The dealers in my area wanted almost $5.00 per bolt and they had to special order the bolts....8.5mm or 5/16 size washers is what you need.
What silcone are you using
I use versachem black RTV
Why are you installing the seal upside down? It is my understanding the seal should have the lower diameter on top..like an upside down V. You have it the other way? Right? Any leaks?
No leaks. I install them just as the others came off. There were no leaks with the old tube seals. No leaks with these either.

Helping Hand Auto Repair The fel pros are different. You might want to take another look.
This car was done a long time ago. No problems reported.
There's two semcircle tabs on each spark plug tube. Can lift with a flathead screwdriver + hammer. This makes it easier to remove the seals. You can also warm the new seals to help seat. After the new ones are seated, you can hammer those tabs back down.
Also found out this is where the oil sludge can start from in 97 - 00 engines... the oil gets clogged under the valve cover baffle plate. Probably your only chance to clean with degreaser or heat before you do the valve cover up. If your pcv is straight, you don't have to worry about this step as they made a new design valve cover that doesn't get clogged.
Did you do this Bc the burning oil smell from the leaky rear bastard? Great video BTW !
Yes. Plus you can just see all the oil building up
@@HelpingHandAutoRepair Same here, did mine yesterday. Glad I did Bc damn that throttle body was filthy. Previous owner didn’t do his chores that’s for sure. 153k on it, runs amazing especially now. I did the rear first Bc it’s the hardest and that kicked my ass so I did the front the next day lol no more smell, dry as a bone. Very happy
How do you remove the harness from the rear valve cover?
There is one bolt on top and 2 on side. 10mm
Top has a stud, #5 inverted torx, it helps to take it out.
Hey how do u remove the wire under the throttle body? The one directly under.
An electrical connector? Or is it some other type of line? Forgive me as this was some time ago.
All good. It was an electrical connector. It was the middle one out of the three when trying to remove the throttle body
I have a picture of it if u need to see the exact connector
Porter Eaglin-McCabe did you already get it off?
Nah I haven’t been able to take it off. It’s like stuck and I’ve gotten the other 3 but the one won’t move
Man, that back wiring harness has me stumped! Can't get it off--I will try to remove that Y bracket and that third "hidden" 10mm bolt....this thing is a bear!
Dude I literally just yanked it until the plastic on it cracked so that it was actually movable
Sometimes this is necessary lol
@@majormax3764 Did that damage the wiring harness? Because I did that too, but I haven't put everything back together yet. Just wondering if I created a problem by doing that
show the back cover remaval always the front
Can’t get the camera back there. The cover is the exact same cover as the front. I explain the process very easily.
what year make model is that car? I ask because it has a strut tower. I have a 94 camry V6 and would like to add a strut tower.
Not sure what year this is. It was a customer’s car and this was some time ago. You can just buy and aftermarket strut tower bar I’m sure. Even a bar from that generation camry should fit as well. Just gotta do a little
Homework
Is there a plenum gasket that has to be replaced or no?
They are reusable. You can replace it if you would like to.
On resin manifold units the rear 14mm head bolt is a nightmare
Agreed
i need to do mine on my suzuki grand vitara 2008 looks like a pain in the ass
You are correct. Taking off the intake manifold will be fun.
@@HelpingHandAutoRepair yea i need to do the timing chain cover too lol
What torque wrench do you use
Craftsman in/lb wrench
why are you cleaning that over the open area?
did you replace the plenum gasket?
No.
@@HelpingHandAutoRepair thank you
What about any sealant, also one time use valve cover bolts ,,You dont replace those?
I have an issue with the nuts holding the egr valve in the rear, they appear kind of rusted. If there is someway I can take this camry to you, by all means I will pay to get this fixed. Family car, Its still going stgrong at 181K. I will be glad to get this job done.
Where are you located?
@@HelpingHandAutoRepair I'm in Cleveland, Ohio. I mean if I have to drive a bit I'm willing.
you can send me an email and perhaps we can exchange contact info, I even bought the EGR valve and its still new in the box, the sun is out and finally got over the frigid cold temps.
@helping hand auto repair HELP!!! HELP!!!
Hopefully you were able to get the camry sorted.
This helps but could you please change the camera angle when doing the back side of the engine?
It’s definitely hard to even show everything back there. Sorry.
And than I paid someone to put it back together 😁
You put the Tube Seals on Upside Down. The rounded edge, on the Fel Pro gaskets should be facing the Cam cavity on the Valve Cover. You shouldn't have to 'feel the tube' around the seal when reinstalling the cover. The Tubes should just funnel right in. Also, I noticed that you were removing the Tube Seals the "Hard Way". There are two very small tabs that are holding the old Tube Seal in place. All you have to do is slightly bend them up, with a small screwdriver, and get them out of the way. Once you tap in your new Tube Seal, the small tabs can be lightly tapped back down. For reference, they are directly beside the "rivet" on either side of the Tube Seal.
Good call. This is what I observed too. The tube seals are installed reversed. Should still work though.
I am replacing my 2000 Sienna VC seals right now. Got a little confused about the little tabs you mentioned that hold the tube seals in place. I consulted a Toyota dealer, the tech just told to yank the old one out and tap the new one in. But I am concerned the new seals will be scratched or damaged by the tabs.
I just learned from other videos that the tabs should be bent upwards and back down as you stated.
Good video though. Very clear and informative. Thanks a lot Helping Hand.
Also, I heard that adding a washer to the VC bolt will help to torque it down properly to prevent leaking with new gaskets.
For reference to everyone reading. I’ve been popping them out with a flat head for YEARS without any issues. Works just fine. I don’t waste time bend up little tabs. They are so small there’s no problem.
How many hours did it take
About 4
Why is it always the back one that leaks?
I'm decent with car repairs but sometimes, I'll pay someone else to have the headache. I might do my front gasket.
I feel it. Video is here to reference if you need it 👌🏽
I just did this job but when i turn on my car it smells like its burning a lot of oil and smokes do you have any idea why this happens?
If you didn’t clean off the old oil that has been leaking, it will take some time for it all to burn off for good. You could also have installed the gasket incorrectly or it may have dislodged.
Helping Hand Auto Repair thank you man
Add 5/16 washer under the crush washer that come with thr cover bolts. Ull thank me later.
Skip trying to get at that Passenger side upper bolt. On that C Bracket.. Just take the bolt loose on the bottom attached to the engine. As that upper one is shrouded by that C bracket..Then just take the bracket with the intake...I have no clue why Toyota counter sunk that bolt inside that bracket...
This looks more difficult than changing the timing belt, seals,and water pump.
It’s definitely not fun haha.
I hear The cover bolts are ONE TIME USE, so unless you replace them, torque value 69 inch pounds won’t mean much.
You can replace the factory wave washers if you would like. Or you can just torque them down as I said and have been doing for years without ANY problems. 🙃
bolts are so hard to find...you would think toyota is popular
its easy should be able too, should be able too, says for another minute XD like how he's like clean off the groves and clean out the gunk but has the valve cover over the valves and cams while cleaning off the valve cover. ohh and take a screw driver and hammer to get the old gasket out XD
How much would a job like this cost?
That could vary significantly depending on where you live and the labor rates. In my area this is probably a $600 job give or take a couple hundred.
@@HelpingHandAutoRepair Was just at a shop where they charge $100/hr. Quote was for $420 but they said that if they break a sensor or other parts it could cost more. Not sure where to even take it from here. Go for it?? This is why I soooo look forward to owning an electric vehicle one day. :D THANKS for your response!!! You do great work! Oh, btw I live in Chicago.
Might as well change the spark plugs and the coils while you have it all took apart
Spark plugs I’ve mentioned. Coils no.
@@HelpingHandAutoRepair sorry I missed that but great video I had to change mine on my 2003 es 300 and you helped me out Thank you so much
Find them in vehicles as late as 2006
You shouldnt have to remove the throttle body from the intake manifold you can take it all out in one peice
Didn’t want to have to drain coolant and rebleed the system.
@@HelpingHandAutoRepair fair enough lol
8:55 I like how u skipped the part that’s frustrating me the most, getting the gasket into the valve cover 😡😡😂😂😂😂
I showed how to put the gasket into the valve cover. I didn’t show me putting the valve cover back onto the head. Figured that was pretty self explanatory.
U didn't show how u remove the rear gasket
2:36
U should go in closer with the camera next time
Is there something you need clarification on?
Why did you show how to take off plenum
Because you need to in order to take the back valve cover off.
im almost certain that the solara went on the market the late 1998 marketed as the 1999 model. this shouldn't be a 1997
My apologies I misspoke. This was probably the first year at 1998
Build date showed ‘97 in the door jamb but it was late 97 so was a 1998 MY.
How long of a job is this???

All those different sounds are one bird, a mockingbird.
You didnt show the most critical part!. The harness removal!
I told you exactly how to remove it lol. It’s not hard at all. I told you how to move it and that you would need to work around it at times.
I had to unplug the oxygen sensor from the wiring harness to get more wiggle room. The power steering hose wasn't an issue for me. But I will say this job WORE ME OUT!!!! Now I have to do the exact same job on my kids RX300
Yea this job sucks
Btw.....you did a fine job on this video!!!!
This is $500 job where I live.
Never use the Fel Pro Blue Gaskets. They are Nitrile and they swell. Only use Natural Rubber.
Just did this job with felpro been holding up great for about 6 months never heard anything bad about them
@@calebp2743 I'm a Toyota MDT, only use Natural Rubber Gaskets. As for the 6 months, that nothing, wait for 3 years and then when you have to replace them, when they are taken off, you will see that they are "Swelled"
Sorry. I use Felpro all the time. Been on my 2JZ motor for 5 years now. Zero leaks. Not to mention all the other cars I have done now for the past 16ish years. Also you need to speak facts instead of lying. Gel-pro gaskets are made of silicone rubber not nitrile. That is very incorrect. Factory gaskets are also made of silicone rubber.

@@HelpingHandAutoRepair yeah thanks, I discovered the "beginning" at 10:55 and updated my post to say so, but I guess it didn't appear edited to you.

I suggest editing your video to where you can delete everything in front of time 10:55 Be well!
I will consider doing so. Thanks for the suggestion.
Good video but why are you removing seal/gasket on top of the engine just grinding it back n forth while you try to remove every seal. Making me cringe. Not saying it’s doing damage but I’m sure there’s a better place than just to flip the valve cover over an let it scrape all the internals
Because after working on cars for years, you know what you can do and what you can’t. As you just said yourself, “…not saying it’s doing damage…”
@@HelpingHandAutoRepair fair enough.
video skips over getting the back valve cover off pass the wiring harness. The wiring harness is in a very tight bundle that is boxed in some sections, and tightly wrapped with tape everywhere. This guy completely skips that part.
Keep watching the video.
2:39 is explaining that. Just keep watching the video.
You leave a lot of detail out. Folks want to see do everything. Don't say move this and that -- show them you removing this and that.
You can make a video showing what I missed. You simply can’t show every little detail. Cameras don’t fit everywhere and can’t see every little
Thing. Lol, people always unhappy.
