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.

My fel pro gaskets are both too large for my Montero sport. I’m at a “loss” with how to keep it in place. It does not stay at all. Super frustrating

What product can I use to “glue” the gasket in place bc on a ram you need to jam it back in place and the gasket keeps getting pulled out of the grove

Always 👍👍

That’s awesome v

I just installed new FelPro vs13379 gasket without sealant. It leaks a little by bottom corners. Should I remove and and sealant?

Thank you God bless y'all

Just bought a set of VS 50247R "rubber" VC gaskets for my 87 F350 6.9 Diesel. Install dry or RTV in the groove? No instructions on the box regarding using sealer. Everyone has an opinion. I'm leaning toward going dry and see what happens. What does John G and Fel-Pro say?

I use mostly Fel Pro gaskets on most jobs and on the corners of the timing covers and the corners of the main caps I tried dry before that's a no no that was a lesson learned for me great thing I didn't have to raise up the engine to remove the oil pan.

The gaskets on a coyote SUCK! They keep rolling out from under my valve covers.

I've rebuilt quite a few old engines from classic cars that pretty much used all cork rubber gaskets. I've always used a very thin layer of rtv on the block side to stick it on for instillation. I finally got to build a modern engine a while back and I've gotta say, I'm a huge fan of the blue rubber gaskets! Especially the oil pan, but also the ones that snap into groves. It's such a great improvement and not getting rtv all over myself had me happier than a fly on fresh cow shit!

I've always used fel-pro Gaskets, but I built an engine a couple years ago and a very reputable mechanic told me to never use them because they're junk. So I bought my gaskets from fel-pro because I make my own decisions and they've never let me down. Engine runs great and doesn't leak. Some people just get weird ideas in their head and others listen to them and follow along. It's easier to follow than it is to think

& the way the other dude says, “conversation”. I just hear Bobby’s World… “Now, don’t-cha-know-Baaahbbi…”

I really hate the way you say gasket, lol.

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.

I read the title so watched for 6 minutes and completely missed the part where you installed the valve cover gasket - left scratching my head, oh well, the tiny little spots where the gasket was pushed down just came back up

Tha ks boss u answered my questions you did a better job then my mechanic did.

Very helpful

I've been using your gaskets for like years 40 years

I'm a master machine for lockeed Martin

I love you guys nice job

Can I purchase these snap-ups for specific vehicle models?

Does the original molded rubber gasket have to be removed before Installing the felpro one, I would think that it wouldn't seal as good without removing it.

Great one. Thanks

Yea no

That's nice on a perfectly clean valve cover, but what about when it has oil on it, and the gasket won't stay in? Is there a fix for that? Because that would be useful.

I got 1 torque in, started the truck ran for 2 seconds, cause i thought i forgot to toque the rocker rail, i took it back apart to re inspect, upon reassembling its already stretched 1inch excess and gotta get new ones 😂

Why doesn't Fel-Pro make an oil pan gasket for a 7.3 powerstroke?

I agree . For cam cover : dry, no RTV at all.

Snap up's are a life saver!!

Six years in my Subaru Forester. No issues. Excellent product.

Put these in my Subaru Forester 6 years ago. So far so good.

I have a question can you install a valve cover gasket on a 2012 Kia forte with the motor warmed up the only reason I'm asking is because I have to drive my car to my mechanic to have him put a valve cover gasket on it because mine is leaking

Sold!! Just bought on Rock Auto largely due to this ad.

Do you adjust valve after replacing the gasket?

I have never used them personally, but I did see them installed on a 444 diesel. Very impressive.

How about designing a $50 oil pan gasket that does not require that lousy RTV??

This was very helpful. Thank you!

If you're into an engine for timing chains, etc, you're a fool to reuse a timing chain tensioner. Get out the OEM shotgun and start blasting away. Do it right or don't do it at all.

So the takeaway is the more etc the better

If you're not supposed to use rtv, then how do you get the intake gaskets to stay?

Can felpro rubber/silicone gaskets (oil pan, valve cover, etc) be reused or do they need replacing every time you take them off?

You should check out the video I made about this issue. It's very simple.

Could i do i a thin layer of gear oil specific rtv on both sides of the gasket for my differential

My gasket keeps falling out after flipping

Those spots on the GM V6 valley seals are a pain to seal. Very easy for the seal to fail when not using enough, but using too much just dumps sealant straight down into the block. Adding boost and increasing crank case pressure tends to blow these gaskets out immediately. That's an ancient PC back there.

What about rtv or gasket dressing?

Used your end seals. They both failed... both split at the ends and popped out from under my intake on my gen 1 SBC 350... RTV or nothin ✅

Haha I’m the fourth comment
