How to use RTV and properly make a gasket
Вставка
- Опубліковано 28 вер 2024
- Learn how to use RTV to make a rear differential gasket, waterpump gasket, oil pan gasket, thermostat gasket, valve cover gasket, or whatever needs a gasket but you cant find a gasket. Using this method will help make sure you seal whatever you are working on, properly. If you dont use the RTV gasket maker correctly then you can get a leak and all that hard work was for nothing.
Here is the RTV I used: www.amazon.com/...

Hahaha, just stumbled upon this. Couldn't agree more!
3yeare you been following 👀
Just wait, he gets WAY better later on.
I like to do one additional step to insure a leak-free seal. I clean BOTH surfaces with some alcohol BEFORE starting the RTV bead. I feel the adhesion is better-especially with valve covers and synthetic fluids.
Should clean both with brake fluid, maybe ChrisFix will remake it one day with the accumulated experience eheh
@@joaquimt.duarte2538its implied dumb dumb

Good video. I'm actually one of the Permatex technical trainers based on the east coast. We now offer a special silicone just for rear differentials that you can find at many parts stores. Especially good for use with synthetics.
Thanks a lot! Glad to see a Permatex tech trainer is acknowledging my work! It is a great product!
How do I know if the rtv silicone is gear oil compatible I bought height temp red rtv gasket maker
Hmmm, Chris Fox commenting on Chris Fix videos...
If you're a Permatex trainer, you should know that there are so many Permatex products that it confuses newer customers. Permatex needs to start putting up charts and graphs on the store displays like FRAM does. I've actually bought JB Weld stuff over Permatex stuff because the JB Weld package said it was for my application, while Permatex had like 8 different products and no definitive guidance on what to use each one for. Yes, there are YT videos, but if I'm standing in a store I'm not going to spend 40 mins staring at my phone to figure it all out.
@@cbpuzzle Same here. I bought permatex, but I'm searching now to see if its good for my application.
My nephew showed me some of your videos , he's at the age where most young fellas get into cars . I can say overall you have the makings of a good instructor at a technical school . I don't know if your just a gear head or a professional mechanic . If you are your certainly someone who enjoys his career , and probably does honest ,quality work . As for myself , I went to to work for Plymouth after I came home from Korea and retired in 1991 . If you came into the old North Assembly , I would have reccomended that they have hired you immediately . I was from the school of thought that the men who loved cars were the best candidates to build them. Keep up the good work and keep em rolling ..
These videos earn him millions of dollars a year. Hes literally a multi millionaire. ChrisFix won't be teaching at any schools anytime soon
@@placeholdername3206haha isnt that nuts? He definitely deserves the success he has had. This guy really did just start making videos with his only intention to help people. Such a good dude!
Obviously not just a gear head with every repair for us we could need. You owe bro a thanks lmao.
I love that you read the comments even in the first videos
Crazy watching this in 2023 and seeing just how far good ol' Christopher Fixopher has come
All gasket makers and flange sealants need some time to cure before the assembly can be put back into service. Failure to wait the correct amount of time can compromise the integrity of your seal. Typically, RTVs require a minimum of two hours to set up and 24-hours to achieve the full cure that’s needed before adding fluids or returning the vehicle to service.
When you're done making a gasket just hop in and go for a drive bro it's all good
@@MrAuto727 Who farted bro?
this is a great young man who knows his stuff...obviously he paid attention to someone knowledgeable and learned and made better
Jill Boles Thanks lot Jill! I do my best to teach others though my videos so they can hopefully learn, save money, and get the job done themselves!
I do this but I spread it thinner over the whole bolt area with my finger. Then I put the oem gasket on that, making sure to line the holes up, then let it dry face down on a piece of cardboard with some weight on top of it. Once that's dry I spread a thin layer on the opposite side of gasket, put pan on vehicle finger tight, then torque after 20 minutes. After 1 hour I add fluid and test drive. In the 30 years I've been doing this never had a single leak. In my opinion a lot of people that have leaks are doing this when it's too cold outside. Remember RTV stands for (room temperature vulcanization).
I put my rtv on and let it sit for 15-20 mins. Then i slammed it on and tightened it by guess estimates instantly. The rtv splurted out the sides but it doesn't leak.
Thanks for sharing!
ChrisFix Loctite 5922 is also a good product if you want to glue your paper gasket on.. But remember that the glue needs 24 hours to dry. Some people have used very thick bearing grease to glue the paper gasket into the part. It works as the grease just dries off and is squished away when you bolt on the part..
Ford M Garage w
haha, you wait 20mins? i just whack a good bead all round and put it on straight away. have done for over 10 years, never had a RTV seal fail.
Yeb, smear it on, and torque it down. Job done.
Wow thank you man! I installed a water pump with blue rtv gasket maker and I didn’t give it 15 min to dry up a little instead I installed it right away and I did do everything else like hand right and let sit for an hour and then torque it to spec, but then the next day when I added the coolant it leaked bad lol well now I know what I did wrong thank you so much for uploading these how to videos
Just a heads up for anyone doing this, Permatex makes a differential product. It comes in a GREEN bottle called “Gear Oil Gasket Maker” and it has even better oil and pressure resistance than the black. It’s not resistant to gas though so it’s good for differentials and transfer cases but not on the engine block. If you have an older vehicle with a leaking diff, a large diff, slip diff generating heat, venting issues… I would recommend the green.
can I use ketchup instead?
rodstartube Yes, as a matter of fact you can. One little tip about using ketchup though is that it wont help you any. Good luck, little buddy!
BBQ sauce works better.
I used mustard on mine and it worked great 👍🏼 now i need to replace my blown out rear end
Not recommended as it may cause hungriness
Someone needs likes.
Excellent video. Just a small tip for European/JDM cars with tight tolerances - make the bead 1-2mm. Or less than half of what Chris is showing here.
Cris simply the best.

Hey Chris my name is Chris also this was a helpful video on how to make a gasket out of RTV silicone my son was changing his oil well he turned the oil drain bolt to the right instead of turning it left so the oil pan has to come off of his toyota 4runner it stripped the bolt out.Thanks Chris
Wish there was a mechanic like you where I live.
thank goodness for videos like these
Seems all good in your procedure. Personally I would also loop it fully around the holes, not just the inside. Although I would close around the holes after I'd done the main run. Anyone else have thoughts on this ? Oh and for anyone with a lathe or know someone that does, I would get a couple of longer guide pins to pass straight through cover and then through the tapped holes and then press home the cover. Temporary studs fixed in the housing could work, but if you miss hit them on approach then your gonna have to fix that sealant smudge again.
You're always doing great work,Chris! Keep it up!
I googled "silicone instead of gasket" and who appeared? Mi amigo! Hello!!! of course! If I was going to pay for all the money I have saved with you, I owe you a brand new Corvette! Gracias Chris!
1:55 that is some amazing ketchup
My 1988 Suzuki Samurai doesn't use an oil pan gasket at all. It is like that from the factory. Only rtv. I could never get a good answer on instruction on how to properly use rtv and the diagram in my service manual is old and black and white so you can't properly see the bead at all. Your video has helped alot.
Also Chris does top detailing vids
Nice presentation, sounds like you did your home work.
Nice video. Sometimes it is easier to line up the piece with the rtv on it if you use a couple studs at first.
Go to the "Prematex website" The high temp red ATV is incorrect for gear oil. Apparently, gear oil will dissolve the red ATV and cause leaks.
The correct Prematex RTV for differential covers is the Green product.
I just just bought some red rtv today to use for my rear main seal housing on my mustang! Had to look up a couple vids to make sure i put it on right. Lol
How about a video on DIY gaskets using an exacto blade, gasket roll, and/or manilla folder?
Great video and I was just wondering would it be OK to use rtv or a rocker cover?
Thank you, I enjoyed your straight-forward approach. I'll be doing this with a oil pan.
Great! Glad it was helpful! Good luck and remember to use high temp (red) RTV and one that is compatible with oil.
thank you thank you thank you, cant say it enough
I'm happy the video helped you out!
@@chrisfix your videos are so well made even i could do it, keep up the great videos , they help so much.most people like me dont have much money but own a vehicle and thats where people like you come to the rescue , thanks
I always put a circle around the bolt holes too.
You don’t have to. It’s a waste. The bolt holes don’t have fluid in them. It’s not a bad thing but just a waste. Thanks for sharing!
@@chrisfix There's no water there, until it gets trapped by gravity in the convenient little wells we just made, along with some dirt. Better to give it a nice little roof.
It’s amazes me that this video was released in 2013 and people are still leaving comments!
First, it must be completely dry. Cleaning with something like acetone helps.
Great videos man I learn alot from you!
Thanks man! Glad you are learning! This stuff is good to know.
ChrisFix Yeah you're pretty good at explaining things, clear and concise. Do you have any fuel line/top engine cleaning videos?
Calvin Harris
I dont have any of those videos but I can make them (I always look for suggestions on what videos my subscribers want). By fuel line /top end cleaning, do you mean with a cleaner like sea foam? How do you know you need to clean it?
u can even throw gear oil right away if ur in a hurry, iv done a few times idk if iv gotten lucky or what its certainly better to wait obviously
Buenos días,, Of Tijuana,baja ca. ,,,,Saludos.
If you watch at 4:45 you will see that Chris did not torque the bolt at the 4 o’clock position.
If you really want it to stick and seal! Use silicone "Adhesive" sealant! Clean the parts with brake kleen!
RTV under pressure, Adjust curing time, - I'm using it for a swimming pool multiway valve, ive done this before but this time I am leaving it over night (say 12 hours) after just hand tightening it, I am not sure if the RTV gets tacky more slowly inside and last time I did this I noticed a minor leak, so this time I think as the pool multiport valve gets a LOT of water pressure when operating I really want the RTV to be a little more cured before I tighten to final torque, just a thought as I dont want liquid RTV uncured belowing back out and up the bolt holes etc. The valve design (Espana 6 port) is shit anyway and no intermediate gasket. RTV seems fine. I am using a Thai branded equivalent. as I am in Thailand.
you sound like Walter Jr. from Breaking Bad!
cvturbo haha, I will have to try to find a clip of him talking.
cvturbo Their is NO WAY Flynn could handle doing this... without falling over.
With Transmission Pans - how long should you wait before driving it after doing a transmission service and applying RTV to the transmission pan?
LMAO
His name is Flynn now..
Hi Chris. Great videos Man. Learning a lot. Some people say use Copper RTV. Opinion please.
Good jobs.
Vid is good to go. Thank you.
The tube says assemble immediately then wait one hour and torque.There should not be a week point in the silicone if you apply it all the way around.
True this is a very proper procedure but when you're changing axle bearings on flat rate, you learn that rtv just ain't that picky in the real world. It's hard to use too little rtv and no big deal if you use a little too much. Smear it on, run down the bolts and let her roll.
haha yea I guess flat rate work needs speed and as long as it works it works.
ChrisFix, buy the way, didn't mean to come across as a jerk. There's lots of good stuff in your videos. Take care man.
Once again nice video. I'm working on the oil pan on 2002 Maxima. Can you tell me how much torque I'm gonna apply? TIA
"Take your time"
As simple as you think it might be.. pay close attention!! The sequence and time is critical!!
I don't use high temp red rtv on oil saturated parts as it's not resistant to oil or gasoline over time. Black rtv or gray motoseal works great for longevity.
Thanks for sharing.
Hi, I did exactly what you did in the video, waited the hour to tighten, when I tightened the bolts more goo was oozing out? I thought waiting the hour would of set it off
Hello! Did you smear the rtv on the gasket? Or did you just leave it like you showed on your video.
They make a front/rear differential specific RTV now for those covers.
No "Hey guys, ChrisFix here!" lol. You seem much more confident on your newer videos but the older ones are no less informative.
Just earned yourself another 👍 and sub...😎👍 excellent tutorial video on how to use the RTV gasket maker correctly nice video buddy I appreciate your time & effort that went into creating this video for us to watch & learn from I currently purchased the red high temp rtv gasket maker to reseal my gy6 150cc scooters valve cover after I perform a valve adjustment on her that's what led me into watching your rtv how to use correctly video ....😁👍 thanks again mate 😎👍
Can you do a valve cover gasket on how you can use silicone
I need a gasket for my carburetor on my lawn mower(don't laugh, I know this is off subject) can I use this? Good video as usual!
Make your own gasket: amzn.to/1UoHmLl
If you can find a gas resistant RTV that would work. This one I used is oil resistant.
How to use it where gasket is aslo present but we have to use it to prevent leaking ???same procedure or slightly difference?
While you had the barbeque handy you should have cooked up a couple of sausages and let us know how the goop performs as a ketchup substitute!
What do you use to remove the excess material when it is all tensioned, you know the excess material that gets squeezed out. ?
You could just wipe it away with a paper towel
IMPORTANT: According to manufacturers recomendations you shall NOT wait 15 min. but assemble parts immiditely!
Who said to wait 15 minutes?
Don't think we didn't see you miss tightening that one bolt ;)
GOOD GOOD JOB NICE ONE.
Should I be ok if I did not let the RTV sit for an hour before torquing down. I just installed and torqued down immediately ... now I'm concerned? Thoughts? It was in a engine oil pan
most likely you will be fine, but the main idea to let it dry is so the rtv does not get spread out as much and makes a better seal, if u notice any leaks u will need to redo it but u should be fine
I ordered Goodfo RTV silicon right now
Aren't the red colored RTVs acetic curing? If so, i think they might corrode metal. I think the grey ones (oxime or alcohol curing) are better on metal stuff.
No, you can use it on metal!
Good video man
Suporno flairboy Thanks!
Better if you make a circle around the bolt holes
Cab you use this to make a gasket for small engine fuel float bowl? It's the little bowl at the bottom where fuel collects and has a drain screw.
Although an old video,I want to ask,why you should wait to get tacky? Years ago, at my first attempts with car repair/service etc i didn't wait,so torqued it instantly... Last 2 years,I do that method,but haven't spot any difference.... Actually I'm sure that there is a difference,but haven't spot it yet :P
Thank you Chris
I use 12 pack beer cartons to make Gaskets. They also work great for sun visors.
Thanks for the tip!
This isn't a tip video! It's a tutorial video.
Brakleen leaves behind a film that some sealers do not adhere to very well. Cleaning with brakleen is fine, but finish it up with rubbing alcohol.
dissevered I used chlorinated brakleen which leaves no residue. But yes, you are correct, if you are using non-chlorinated brakleen, def hit the surface with alcohol after! Thanks for the tip!
I didn't know that. Thanks!
What if I don't let it sit for an hour and tighten the bolt instantly?
Someone used this stuff on my vehicles oil pan and oil pan gasket. I have a gm 3800 series 2 so having the gasket glued to my pan is not allowing me to get the pan down.
Try going around the pan with a razor blade or exacto knife and it should come off no problem!
Very good!
Thanks!
good video!
Thanks!
I didn’t let it sit on the valve cover of my trx300ex before final torquing will it be fine or do I have to redo it
Not sure if I'll get an answer, but I'll give it a go. I have a corolla ae101 and got to change the water pump bypass hose. I can't find the gasket that fits between the engine and the conduit/pipe connected to the bypass hose. Can I use RTV to make my own gasket?
There are silicone gasket makers specifically for water pumps and thermostats. So yeah. Just make sure its the right stuff.
Перед Как закрыть крышку хотя бы надо было показать крышку с герметиком (без прокладки )...
You forgot to torque the lower middle right bolt Chris...
Can I use this in a pool situation
Will it hold if u have a dent on the mating surface
Kinda weird watching this now without that iconic "HEY GUYS!" intro. But your videos are still heck relevant 8 years later. Watching this to know more about RTV gasket. Thanks Chris! Much love from the Philippines!
Yeah
it's fun to binge on your older videos once in a while
Awesome!
Im watching today because i need to make a gasket for my intake manifold and im not wanting to pay the 30$ for a gasket since my car is over 30 years old . So a 10$ bottle of the gasket maker is way cheaper and hopefully will hold well enough
I have been using #2 yellow pencils to line up bolt holes over 45 yrs....try it...
Great idea! thanks!
How so? Can you explain
@@eltonpham2165 I think he means they're used as pins to find good placement
I get it, but why not just use the bolts? Is there some advantage to using the pencils? I would think long pencils in a tight space could be a hassle, but I'm new to car work so idk. I'd love to know, I like learning new tricks.
@@DanteYewToob easier to slide on the pencils to the mating service instead of having to get close with a short bolt. Less risk of making a mistake! Sounda like a great idea though and I wanna try it haha
I’m watching this video in 2021 but your videos are timeless. Thank u Chrisfix
If you use two bolts with the heads cut off as studs, it works without worrying about getting it on wrong or smeared.
Man, watching these mechanical videos is addicting, I'm learning a ton.
Glad you are learning a lot!
Good video, however I would recommend to do the first round of torquing with 50% of the recommended torque. After 1-2 hours, run the final round of the remaining 50%. Never leaked a single seal for last 26 yrs I have been using this procedure.
Hi, I'm wondering if this would be the same application (let the sealant seat for 15minutes before putting the cover back) for the front timing gear cover? I've installed mine but oil started to leak on sides after some time :(
please advice and thank you in advance
@@jaysagrayum7448 Jay, did you ever get this worked out?
You can use 4 chopsticks one in each corner bolt hole in the differential to use as a guide when attaching the cover. It will make sure the pan goes on perfectly straight.
Genius
Oh my god this would’ve been way easier. I now know for next time. Thank you kind Lizard king
yeah thats an old school trick, used to do it with random sticks and twigs on the ground, or some pencils.
I let mine sit overnight after the final tighten before adding fluid.
Thats the correct way to do it, I normaly just tight a bit by hand and then I wait 4h, after that I do the final tighten.
I wouldnt use high heat for a diff cover. Permatex "right stuff" only.
Best rtv out there is right stuff
@@christopherhendricks4369 Amen I've used the Right Stuff and not even a seep years later .
Right stuff is surprisingly superior.
Nice job,have been watching your videos for some time now.However i have some concerns about the method.
In permatex products the only gasket maker that need some time to become tacky before assembly are the solvent based gasket makers.
The silicone RTV gasket makers all mention that assembly right after you spread the bead with normal pressure so as to for the RTV to spread and after ten minutes or one hour,(depends on the type)torque to specs.
The only exception is "permatex the right stuff" which have no cure time,just aplly assemble and torque and your good to go.
Going around both sides of the holes might prevent bending of the flange.
Congratulations upcoming 4m subscribers
You forgot to tighten the bottom bolt on the right side at the end.
You forgot to torque down one on the right, unless you did it off camera. But thanks for the informative video.
twistdshade Good eye. I torqued it down but edited it out by mistake lol. Glad the video was helpful! Definitely consider subscribing! New automotive "how to" videos every Thursday and most Mondays!

twistdshade Great! Glad you subbed!
ChrisFix Hey if you ever get the chance, post some stuff about small engines. Single cylinder stuff like mopeds and lawn mowers. :) That's all I've been working on lately since the parts are so cheap and lots of folks have old broken down yard equipment collecting dust.
twistdshade That would be pretty cool! Good idea!
