- Many vehicles are originally equipped with a differential cover that is sealed with RTV rather than a gasket. To learn why installing a Fel-Pro® differential cover gasket is a better way to seal this type of cover, check out this video featuring Technical Product Specialist Mike Hinderer and ASE Master Certified Technician John Gurnig of the Fel-Pro Field Test Garage.
Featuring proprietary application-specific technologies for a superior seal, Fel-Pro differential cover gaskets are designed specifically for the repair environment to help seal imperfect sealing surfaces. Mike and John review the advantages of installing a Fel-Pro differential cover gasket rather than using RTV. Experience the Fel-Pro Difference and see why we are The Gaskets Professionals Trust™.

Thanks for creating this video. I was specifically told by the part store owner to never use any additional material such
as silicone or gasket maker to your gasket. I was very curious and asked why, he stated the Felpro blue gasket will absorb the gear oil and create the actual seal within minutes. Might be worthwhile to mention this next time as it provides an explanation that makes sense and add trust toward your product, just a suggestion! There’s a bet amongst my weekend mechanic friends this won’t work, lots of beers are on this one and I expect a whole camping weekend this coming summer enjoying their beers!
Did you win?
Hi Paul, hope you won your bet. I attempted to use the Fel-Pro Gasket for my Dana 44. Unfortunately... it still leaks. :( Wondering if I should just use RTV.
Did you win the bet? I know this is from 2 years ago but I just watched this video now lol
I’m using a Fel-Pro gasket on my differential pan. No silicone at all. Thank you!
This works... until it doesn't. For fancy billet or cast covers and stuff, I might consider a gasket. The issue is with most factory diff covers... they are stamped steel and when discussing a sealed gearbox like a differential case, the gasket allows for compression when you torque down the thin, stamped steel. That creates "waves" in the cover mating surface. The area around the bolts compresses and the space in-between the bolts can buckle upwards. Over-torquing makes the problem dramatically worse on top of it all, and is the cause of most jobs that leak. I recommend using RTV only (with stamped steel covers), and use the stuff designed for gear oil so it won't dissolve or break down. Personally, I use the Permatex brand (it is in a green tube and marked "for gear oil) , but I'm sure there are others rated for this use as well. As always, SUPER-clean surfaces and bone dry after a sterile scrubbing with brake-clean. And even with no gasket and just a thin layer of gasket maker, DON'T over-torque the thing, and DO let it cure before you fill. It may suck waiting, but no leaks is the name of the game here. If you find yourself in that bad spot, spend 30 bucks and replace the cover with a new one and do it proper. Some folks may have good luck using the gaskets, but I've found a 100% success rate using the RTV method and by proper torquing. Fel-Pro makes top-notch gaskets, but I wouldn't use one on this application.
Lubelocker diff gaskets solve every issue that you mentioned. Sorry, Felpro...but your gasket is extremely inferior to the Lubelocker.
@@gdb5448 completely unnecessary to spend that much money to seal up a diff cover. 2 bucks worth of the proper RTV applied in a proper manner will permanently seal a diff, and it'll never leak. No need to waste 30 bucks on a re-usable gasket unless you are doing swaps all the time
Used this today. Worked great!! Thanks again for making such a great product
Yeah, this is one application rtv wins out for sure, unless the lubelocker is in your budget of course.
For decades I followed old school advice, rtv on almost everything. Until, I decided to go by the book on the water pump gasket on one of my Jeep XJ's and go paper gasket only. I could not get the tiniest leak to stop on my other XJ. It's so tiny I haven't even repaired it yet (3 years now). I've also used my right arm as my torque wrench forever on the non-super critical bolts (almost always successfully, +99% of the time). So, this time I also torqued to specs. The correct torque was probably the biggest reason it has never leaked though. As previous poster stated, cast vs. pliable (thinner) stamped seal are completely different animals.
For me it’s also just not having the hassle or risks with RTV, it’s harder to mess up the RTV and you also don’t have to wait the 24 hours. That’s great for a shop if they have them available.
Just what I was looking for.
thanks for this. i'm having to do it over again. this time i'm using silicone to seal it. didn't seal with just the gasket. you owe me $25
Did you have to use RTV on both sides of this gasket?
Same here. Mines leaking still too. I should have used gasket maker on both sides of the gasket before I torqued it down.
Well Im not knocking fel-pro but alot of people dont use the gaskets cause they dont trust them cause it seems they never seal and always leak. I mean the major auto makers seal there diff covers with RTV sealant from the factory for a reason and many auto repair shops do it this way to for a reason. Its the best way to seal the diff cover period. I will say this. Its how you prep the differential surface and diff cover surface that makes all the difference.
Yeah I used fel-pro for my rear diff on my mustang and it was still leaking. Gonna stick to gasket maker from now on
9/10 they with only a gasket is the cover sealing area is not flat. You should always lay the cover on a piece of glass or granite and be sure
It’s absolutely flat.
Correct
It's cheaper and faster for a robot on the production line.

Lubelocker makes a diff gasket that seals perfectly every time, even if the mating surface has some scratches. It is far superior to this thin, flimsy Felpro pos.
I just put the gasket on dry. Normally I use a gasket sealer like permatex 80019. Sunday morning and I ran out of 80019. It sealed dry, it’s been a week.
This is mine and my dad's biggest argument. He slathers everything with rtv, or gasket sticky as he calls it, and I put everything on dry. It drives him crazy and cleaning up rtv off surfaces drives me crazy. I've not had any major issues. Usually if it leaks I re-torque the bolts and it stops. It's important to loctite everything too
@@theamaturepro technology has moved on. I’m old and much like him I was stuck on the old ways. The new metals are stronger, oil is resistant, carburetors are gone, techniques improved and tools are much better. The old days metal was more porous polishing techniques were bad. I work with an experienced younger person and they give me “continuing education “ on new products. It was a young person that told me to put it in dry. Use a sealer on one side if you need it to be held in position.
@@Mytwistedvoices oh yes, the young and old paradox. It's existed since the second generation of humans! What's interesting to me is my dad and I would bicker back and fourth, but with my grandparents generation I listened to anything they had to say and asked as much as I could conjur up. The one thing no amount of education or lectures can teach is the evolving perspective we gain as we get older. I grew out of the argument faze pretty quick, thankfully. But there's still a handful of heated issues with my parents. If there wasn't, I can't imagine life being worth much. We're all very close in my family, there's no actual resentment between us, I realize more every day how damn spoiled I am to have the family I do
Hoping I'd see a question and reply about whether to use sealant with these gaskets. Bummer, guess I'll have to ask it. Does Permatex 80019 sound like proper compound to be applied to both sides of the gasket? RTV? Or, nothing at all?
Nothing at all.
@@antinormality Thanks for the reply. I asked a co-worker same question yesterday. He repairs folks cars on the side. He said he puts RTV on both sides of gasket for trans and differential covers, because, "You just don't want the thing leaking after you're done." Sounds like the belt & suspenders approach to me.
Go check the comments again there are several you do not need to seal it when fluid hits gasket it seals itself
I use 80019 on gaskets with oil. No problem. Both sides.
So you feel the Fel Pro gaskets are better then the Lube Locker gaskets? I'm about to install an aftermarket Diff cover on my 2011 Raptor and I do not not want any leaks afterward.
Did you go with one of these or a lube locker? I'm in the same situation, thinking about getting lube lockers.
Could i do i a thin layer of gear oil specific rtv on both sides of the gasket for my differential

No. If you insist on using a gasket (which I don't recommend at all), install it only on pristine, clean surfaces (the rule is the same for RTV). You need the gasket to bond to the surfaces, which it will do if it is clean, and I mean brake-clean-clean and oil-free. Compression along with heat cycling will bond the gasket to the metal surfaces. It's not a really strong bond and will easily peel off later if you need to remove it, but it's what you need to prevent the oil from escaping. Same rule with rubber gaskets... dry and clean. RTV allows gaskets to slip around a little, especially the rubber ones (which this Fel-Pro gasket is not). So either RTV only without a gasket, or gaskets dry with no RTV. And as always, proper torque. Over or improper torque on a stamped steel cover like this is the worst enemy of all.
Please start making for Ford SUPER 8.8
What about rtv or gasket dressing?
Mines leaking love my life
Has anyone had luck using gasket only?
Yes but make sure the cover sealing area is completely flat.
Lay it on a piece of glass or granite and you shouldn’t be able
To put a 10 thousandth feeler gauge between.
Order thr replacement cover grom gm itwill come with gasket and brackets
Use a torque wrench so each bolt is tightened consistently, and the gasket is sandwiched evenly
Your gasket leaked on my differential 1 week later badly and turned into tissue paper. Your differential gaskets SUCK
Don't waste your time with this flimsy crap...get a Lubelocker and you'll thank me later. Sorry Felpro, but Lubelocker has got you beat big time.
