I recently replaced the transmission fluid filter on my wife’s ‘18 Mazda cx9. There was no factory gasket they used some form of red/pink silicone. The new filter came with a rubber gasket.. it leaked almost immediately. I then found a cork gasket and switched it out and that one began to leak shortly thereafter. I then bought Permatex ultra red and followed the instructions precisely. Solid seal absolutely no sign of a leak 👌🏻👍🏻
I use ultra black RTV and usually never have any issues.. Unfortunately when I was putting a new intake on my BBF 460 I did not follow to directions at all and torqued it down right away and fired it up about an hour or so later and sure enough it blew out the front valley seal.. now I get to redo it and follow the instructions this time 😂
Kids, ALWAYS use a crisscross tightening pattern. Somebody never taught this boy. Also, tightening to spec is great but so is doing so using multiple passes, for instance, if 45ft-lbs is spec, tighten all fasteners to 20lbs, then to 30lbs, then to 45lbs. An eccentric mechanic taught me this years ago. It works.
Awesome! I have a tube of each! I am going to rip off my wife's oil and transmission pans tomorrow! No, not really I bought it to replace small gaskets in an old WWII compass.
Good question. I would NOT use this for a valve cover gasket. There are times when the manufacturer has you put a dab of RTV in places but not for the whole gasket. The design of the valve cover allows the molded rubber gasket to sit inside a groove making a very durable seal.
@Valley Mobile Automotive Have you experimented for yourself though? People always say no for valve covers but I feel like they've never tested it to find out.
@@woooose I'm sure it could work but it would take a lot of RTV! You would need to fill the channel where the rubber gasket would go then have enough protrude out to make contact with the mating surface. Also in the future if the valve cover needs to be removed you would need to scrape all that stuck on RTV in order to apply new stuff for resealing. I think it would be too big of a hassle to be practical.
Lol thanks for making this video for science my man, definitely feel better about forgetting to wait the 1 hr to tighten fully. I had to do a rush job and replace my solenoids also a refill of course so I could get to work your video helped me sleep better 😂 thanks again bro
@@DevontaePayne I was surprised with the results. This is still my work van with zero leaks from either pan. I'll still try to follow the directions but I think having a clean surface for adhesion is the most important part of using RTV.
Thank you So much! This is what I was looking for, exactly!! I decided to drop the transmission pan & change the filter on my vehicle, I had bought all the supplies in preparation but when I had the pan off I found out that Autozone sold me the wrong gasket 🤦♂️ I already had that pan off & the vehicle on my friends lift. He was getting ready to wrap up so In a pitch I used some grey RTV, slapped the pan on, Filled her up & I got her on the road. (I had to get back home) That whole night, I was stressing because I thought I'd messed up the seal due to filling it & driving it before it Cured. Thanks to you & Your video Im way more hopeful & assured now!!😄👍
Glad this video was reassuring! While following the directions is best, sometimes we find ourselves in a pinch. I'm amazed at how well rtv holds up as a gasket.
@@ValleyMobileAutomotive Si I did not quite understand , when you put the bead of silicone are you suppose to wait for it to dry before placing the cover and bolting it down, or do you put it all together, wet and tighten down?
Hey Joseph good question. It depends on what you are tightening and the gasket being used. Most manufacturers will specify the desired pattern (it varies). If I was using the rubber factory gasket I would criss cross the bolts to prevent "stretch" and "bunching" of the gasket on one end. Because this is my vehicle I took some liberties, I also didn't torque the bolts.
As a general rule I NEVER use silicone. I much prefer gaskets. The part you claim gaskets are harder to get off, Well' I say the complete opposite. Silicone can take hours to get off however with a new blade I will have an old gasket off in minutes 'UNLESS' someone used something else with the gasket like copper spray or silicone to help the gasket stick then it will take longer. Anyway against my better judgment I am working on a 40y van and I can't find anyone who sells a Sump gasket so I got some RTV Ultra Black which is why I am here watching your clip. Before using it I wanted to see someone else using it and find out any cons I should know. Obviously there will be some that goes in the sump as you tighten it, Willl Ultra Back break down to mix with the oil or is it likely to block up the oil pump or filter?
So I did not quite understand , when you put the bead of silicone are you suppose to wait for it to dry before placing the cover and bolting it down, or do you put it all together, wet and tighten down?
You are supposed to put it on wet but only finger tighten it until rtv begins to squish out the sides. Then wait an hour before torquing it down. Then wait 24hrs before adding fluid and putting the vehicle back in service. In this video I wanted to see what would happen if you just slapped it on and torqued it right away and then filled it with fluid and drove it without waiting. I also did this in extreme cold conditions, below the recommended application temperature.
@@kevinhoronzy6011 It depends how much gasket maker you apply. The general rule of thumb is 1/8 to 1/4 inch wide by 1/16 to 1/8 inch tall. The bead of gasket maker is being squeezed out evenly on both sides, the inside and outside. So there's not a whole lot that squishes out unless you use a lot of gasket maker.
All I use for air cooled engines is right stuff or gray ultra At least double the cue time works best for me No hurry because there’s so many other jobs to work on
I am changing an oil pan probably in November in Michigan. I see it was cold out when you did this. I don't have to worry about it being over 50 degrees or anything? I was wondering if I shouldn't wait until next summer before I was this video.
I over did it with rtv on new oil pan with no gasket when I tighten pan it came oozing on outside so it had to bleed in the inside am I inn trouble letting it sit for 24 hours
@johncasor9698 My stupid mechanic forgot the transmission filter and ripped the pan open again after was RTV and sealed ..then no bother cleaning old RTC and gasket ....just added some more RTV to fill in and closed it again after putting filter in. Will too much RTV like instead of 1/8 inch bead its more like 1/2 inch or 3/4 bead of RTV ... maybe even a bit more. then criss cross torque and we let it sit 5 hrs ..fill and drive,.. will it hurt the transmission too much RTV like that or the pan in any way?

I have a sand seal on vw engine and it appears they used some type of sealant on it. I think it's rtv silicone. How does one weaken that silicone or remove it?
metal in the oil pan. i would pull apart the engine ASAP and go through it today that quick maybe have the engine out in 4 hours of 6 and tear it down before it blows apart, problem is very small now. wait and then you will say i wish i pulled it apart sooner... Haha...
Good suggestion. The filter was changed while making this video. I wasn't due for it but while you're in there you might as well. They are cheap enough.
The oil and transmission pans will also see minimum pressure (although they both should see heat and fluid flung around) they may be less risk for this type of expedited install - other engine components that see pressure may be much higher risk - I prefer to follow instructions (and still have concern LOL) - Great video though. I was glued to the screen to see what happened.
at least pull of those rod caps and check the bearing. you can spin on a new bearing for about $7 each... i did a lot of them on diesel engines believe me .... and change out the oil pump too i am sure it is junk by now... open up the oil filter and cut it open to see the garbage you can take a oil sample and send it to a lab too ... i have done that...
Yeah, the instructions do say to wait longer than I did. This was a test to see if it would still produce a solid gasket without waiting. I was surprised to see the results turned out really well. In reality I would stick to the instructions. Thanks for watching!
@@muffinatordlux so was the pan sealed and was the “sludge” rtv silicone? To fully cure rtv takes 24 hrs but the vehicle is usable after maybe 2 hrs. For the regular stuff
@@dirtyaznstyle4156 it looked very much like the silicon which had dissolved into the oil and then accumulated onto the oil pickup aswell as sitting in the bottom of oil pan... I let the car stand for 2 days after cleaning up the previous guys mess and the car is running so much better aswell as not leaving oil stains everywhere i park.
I'd be extremely worried about the fluid getting to the rtv and the combination of the two circulating around in the transmission. Seriously could have shortened its life
@@josephhettiger2711 Interesting thought. RTV is oil resistant and can only be thinned with a solvent. In that case I don't think the uncured RTV can mix in any way with the transmission fluid. If any small chunks break loose they will be caught in the filter and won't be able to circulate through the transmission.
I think a follow up video is needed. Pull the oil pan and see how much, if any, excess RTV is in the bottom of the oil pan or now stuck to the oil pick up tube. It seems to me that you used an excessive about of RTV on the oil pan flange. And since you didn't let it cure enough according to the instructions on the package, that uncured RTV came off when you filled with oil and ran the engine.
Right! So guarunteed mechanics are already breaking the rules, myself included. But now I feel better about it knowing it still produces a strong gasket 👍
pull off that oil pick up tube and clean it out or replace it ASAP i had a 1995 Bronco with a 302 engine which is called Fords miracle engine which saved the Ford Corporation from for sure failure it is used in many units you can google that and learn something,,, but the engine i got stuck with had coking [ heating of oil to the point of a raw porous coal state ] that is usually found on the inside of cylinder head exhaust side where it gets very hot and under the intake manifold cross over vent to heat up the under side of a carburetor to vapor a fuel mixture it will break off and drop off into the oil cut outs and lifters movements will break off crystallize oil to help make it into smaller fragments to go into the pick up tube and plug up the pick up tube screen thats what happen to this 302 ford bronco from not changing out the oil every 3K miles to dump out the particles and it starved the 302 for oil and took out a main bearing and blew off to rod big ends just took out the pan rail of the block and lost the oil pan too and i found a crack head so check the pick up tube... i did find a virgin 302 one piece rear main seal which is a newer 302 which you knew that, a 2 piece main oil seat is a older 302 engine but i punch it out .030 over size bore and found a standard crank that cleaned up on a just a good polish so it is still standard size bearings Haha so lucky i am a Master Engine Builder Diesel/gas burner and Helicopter Mechanic ..
why would you waste RTV on that oil pan bolt down holes out side of the hole you got so much Sealer on the inside of the pan hole you do not need glue on the out side of the hold down side of the hole... you do not need to go all the way around a pan bolt hole that is a large waste of good sealant which is not free.. just say`n
way to much sealer it will break off and go into the pump and than if it made it that far go into the filter which is after the pump... very few systems have a filter first then to a oil pump so think about it garbage into the oil pump is just wrong then than a oil filter ??? Haha poor engineering they want the oil pump to fail which is the heart of the motor, Haha.
