Why you should never use RTV silicone on gaskets

Unless you are dealing with a metal type gasket you should be careful when using RTV silicone on gasket material for the simple reason that it creates a very slippery surface and can cause the gasket to squish out and possibly tear. Just say no to excessive RTV silicone usage and help save a mechanic.

From the looks of that red rtv (brittle and no adhesion) , the vehicle was put back into service before the rtv was fully cured. The high temp red and ultra copper rtvs work great, for pretty much everything as long as they are fully cured (and then some!!) before being put back into service.

I'm glad to hear you say that. In the next couple of weeks I'm going at a leaking axle gasket despite good practice with no silicone, just a cork gasket. The mating surface isn't quite right, the cast iron is broken right beside the sealing edge. So I'm going to try to build up the broken cast iron steel to a flat surface, and have been tempted to consider a little RTV at that spot because of the unusual situation. Maybe I'm better off going with RTV alone.... It seems the slippery nature of RTV can interfere with the sealing property of gasket material.

Hello Dave. Looking forward to that video. I've had terrible luck with differential cover gaskets. Its to the point where I only use the gear oil rated Permatex and no gasket. I also let it set up for 48 hours before putting any fluid in if at all possible. Did this when I replaced the seals in the front D44 of my 98 Ram same as you did. No leaks!

This just gives RTV a bad name. Whoever did that gasket used way too much RTV, probably over tightened the bolts (deforming the pan) and likely applied the RTV to a oil soaked gasket. I always use RTV; never had problems. However, I apply a VERY small skin coat to the gasket surface and allow it dry for 15 - 20 minutes before I attach the gasket. It helps keep the gasket in place when I attach the pan. Also, I make sure the pan is torqued down in a star pattern in at least three iterations. RTV works great as long as you follow some basic rules. If applying to a gasket, use a small skin coat. If using as a gasket, apply a continuous bead. No matter what, you always need the RTV to dry for 15 - 20 minutes so it becomes firm yet tacky.

This is standard practice on the Toyota 4AGE. It comes off easily with the handheld drill and a wire wheel attachment. The best way to do this is to put a 3 mm line on the inside of the screw holes on the block, then you set The oil pan on top and push it a little bit, then tighten it down after a couple minutes. They make an oil pan tool for this really easy to use.

On something very large like an intake manifold, I will not use RTV. I started buying a lot of gasket paper so I can make my own gaskets. Generally, I would prefer to wait for a gasket for max of 30 days instead of using RTV. I used RTV on the thermostat housing because it is nearly permanent and does not require removal fo service. It worked great. Bu I don't want to use this on the throttle body even if the throttle body gas low spots or holes on it. I wait patiently for the gasket. There are many things to do on the engine bay.

The EXACT same thing happened to me ...you can't use silicone with a gasket.....the silicone sticks better to the gasket than the metal and when it dries the "siliconized " gasket is so slippery it breaks in thinner places like around the pan bolts and splits open. If you attempt to snug the pan down, even to a low manufactures torque of around 8 ft pounds, the gasket squirms and breaks even more and the leak increases. Who knew??

Assuming the two surfaces are not warped, gouged, burred and the cover actually fits proper and you are still leaking then I have a few suggestions. For me the only sealant issues I face are due to poor clearance or not enough room to work, thus scraping or knocking the gasket out of alignment or smearing sealant (example- sliding an oil pan back into a 4wd truck). This shouldnt be a problem with a rear end so I'd rule that out and move to the next most common issue I face which is over tightening the bolts. Make absolutely sure you are using a torque wrench and torque to spec, never over or else you risk pinching the gasket. Let's say you know all this and have dont it correctly, yet it still leaks. How far apart are the bolts/bolt holes? More than a few inches? If so you may be missing gussets or hold downs. Generally flat or "L" shaped brackets that stretch from one bolt hole to the next and help press the area between the bolts down (often times covers are thin stamped steel and will bow between large gaps in bolts). Let's say none of this applies to you....one last trick to apply, is after getting your surfaces super clean and dry using brake cleaner so there is absolutely ZERO oily residue carefully make a 1/4" bead of black rtv all the way around on the surface of the pumpkin. When I say bead I mean a pretty, circular, wormlike bead. DO NOT smear or spread it, and DO NOT install a gasket or your cover yet. Leave the gasket out this time completely. Grab a beer and wait 10-30min (based on heat/humidity/location) until your bead is starting to be semi solid. It should still be tacky but not squishy (you should be able to leave a fingerprint in it, without it squishing out). At this point carefully and evenly press/install your cover onto the bead and work all your bolts evenly just a little at a time so one side doesnt pull in before the other. If this doesnt work and none of the rest work then it is clearly operator error, maybe a little outside your realm of expertise. Sometimes knowing how to do something doesnt mean you are good enough to do it or have the right touch. Definately not cutting you down, just have no idea what I'm dealing with and the problem seems really strange or like a problem a mechanic wouldn't have. Hope this helps. I'm happy to follow up if you have questions or want more info

You can use just rtv on oil pans. Dont put rtv on a gasket. Oil pans that have a grooved gasket you cant. Some manufacturers use just rtv on oil pans toyota 4ag is one off the top of my head. I know the 90s hondas use just rtv on the oil pump and rear main too block.

What if you use silicone only? Loctite and permatex swears by eliminating gaskets entirely when it comes to stamped parts. or valve covers and oil pans. They even recommend it for the use of high temp aircraft engines. So I think everyone is just as confused as the other.

Any rubberized or petroleum material gasket should not be mixed with RTV as the RTV will break the gasket down. It’s on all of felpro’s instructions.

You made this video 2 years ago. But I prefer Permatex Ultra Black or Gray by itself. No gasket. Specially the cork gaskets. Toyota which is what I have does not even specify a gasket for the oil pan. You can get a gasket in gasket sets But not from Toyota.

Now I just watched a video where the guy used rtv to tack the gasket in place because the gasket wasn't staying put. Then I see this video saying never use rtv but not explaining why. Can you use rtv to tack the gasket in place or not?
