Title: OK Whats the Trick for Valve Cover Gasket
Post by: Sparky84 on March 29, 2017, 02:43:57 AM
G'day All
I have tried but it should be so easy, I have new Valve cover Gasket but every time I turn it up the right way The Gasket Falls out  :dash1:

I did notice that old one seemed to be stuck there, needed a bit of OMPH to get out, not a lot but gentle persuading,

So whats the Trick?

Cheers Alan

I used a very tiny amount of liquid high temp gasket sealant in a few spots.  Just enough to hold it in there.  I put some on my fingers and gave both surfaces a very thin film, waited a min until it gets tacky then put the gasket on the cover.  Not all over every surface. Just in as few strategic spots as possible so it doesn't fall out.

I may get shat upon for saying that, cuz usually you don't want any liquid sealant on the engine.  Hence the minimal amount as possible.  If there's a better way I'm all ears.    :bye2:

Paul, you're on the right track. Traditionally grease is used to hold gaskets in place but I also just use a few strategically place dots of RTV gasket maker to the same end. Just enough to hold it in place. Don't sweat over using too much, it doesn't matter, it just peels off next time you remove the cover.

The trick is this stuff:

(http://ec-i21.geccdn.net/site/images/n-picgroup/DXS_52000.jpg)

Gasket shellac

It's better than silicone because if you slop it a little and get drips, all you need to do is wipe it off with rubbing alcohol. It doesn't cure like silicone and it dries pretty fast.

Grease isn't sticky enough for the FJ gasket.

You can use the shellac around the whole perimeter of the gasket. It will save you a bunch of aggravation.

3M spray on upholstery adhesive works great.

Just don't use any product on the OIL side of the gasket, or risk getting it in your engine.

This is what I use.
3M Weatherstrip adhesive.
A few dots in the corners, let it get sticky, and it works excellent!

I'll be going for a few strategically placed dots of RTV gasket maker over the can of Kwik Grip I have at Home...

Gasket shellac

+1 on this.  Super light coat on valve cover, fit gasket, carefully invert on a flat surface and let it set for 5 min...  now your gasket is part of the valve cover until it needs replacing.  Once gasket is too hard and ribs on engine side surface are gone, peel off and repeat.  Don't even need to clean the valve cover surface unless you used too much shellac to start with.

Forgive me Randy...

Frank,

You are forgiven. We use a very light coat of Permatex Hi Tack in the valve cover valley where the gasket rib sits. Flip it over and let it set and then install. None on the gasket mating surface and you don't need much to get it to set. The hi tack is easily cleaned off when the time comes for a new gasket.

Gasket shellac


Can you still buy this? It was common until the 60's and I've never seen it since. There's a couple of Pre War MG's I work on that still have residue of this stuff in and on the motor that has probably been there for 70 or 80 years. It sets hard and never goes away. Working on an engine that's been assembled with it is a PIA.

Go the cheap buggers way, put the gasket on the head first, doesn't matter which way up, place valve cover on top, wiggle it until it looks o.k, quickly tighten screws down before it changes shape, remember to tighten the screws as hard as possible.  Any bits of gasket end up poking out the sides, just shave off with a blade.

All you guys just wanna spend money!

Just jokes....

Don't forget to throw out the rubber grommets under each bolt, they are worthless since they leak anyway.  :crazy:

RTV silicone works great until you need to get it off an aluminum surface. It adheres so tightly, its difficult to remove without scarring up the aluminum surface, so I have found.

Gasket shellac will come off easily, once set??

Robert, what is cleanup like??

Any auto parts store has it. Something like $2 for the bottle, I've had the same one for years.

It dissolves with rubbing alcohol.

You aren't doing it right. You need to slather a big glob of RTV over the bolt heads.  Seals 'em right up, it does...  :drinks:

Great stuff to use on the low pressure areas of the engine.

I know this is old but for someone like me just getting into this, the gasket shellac worked like a charm. easy cheep. Auto zone had it like 2.50.

Easy!!?? Cheap!!?? For less than the cost of a cup of coffee you could have bought a tube of RTV.
There is a reason this stuff went out of favour half a century ago, it disappeared with cork gaskets.

Why buck the accumulative knowledge of hundreds of members and thousands of motors (in fact the entire worldwide automotive industry) and not avail yourself of modern technology? Modern engine sealants are amazing.

Man, I cut my teeth trying to clean up engines glued together with that shit!

Probably because you don't actually need a sealant in this instance. You need a temporary adhesive that is easily cleaned up.

Trying to clean up engines slathered in RTV isn't really that much better.

I don't use any sealant.

I just place gasket on head then I fit valve cover on it. It takes no more than 3 minutes to proper fit gasket in to grove in cover.

I use this same gasket for last 4 years, and I removed valve cover 6 times during this time ....  no leak noticed so far.

When I replaced my gasket this Fall, 3M weatherstrip adhesive was used in a few spots just to keep the gasket adhered to the cover.  After it dried the cover was just laid in place and fasteners tightened down.  No leakie, no teakie.
