Turns out it was just a cardboard box someone had sort of cut out to make a gasket with. They didn't even take the time to make the edges nice and smooth, just butchered it with a utility knife and called it good. They had made a few gaskets like this - the valve cover gasket which leaked profusely, the carb to manifold gasket as well as the intake manifold gasket at the head.
The cardboard had all turned soft and mushy by now and so there were all kinds of leaks in the intake. I put some fresh gas in it, installed proper gaskets and the machine started and ran perfect! I've used it for a few hours now and it runs great, no issues that I can tell with the hydraulics or hydrostatics either, all in all a great machine!
I just thought I'd share what I found, and maybe see what other kinds of fixes that didn't quite work you guys may have come across FullSizeRender 1 Small. FullSizeRender Small. Joined: Jan 1, Messages: 7, Location: Elsewhen. Cereal boxes make good gaskets for intake, oil drain, etc. Can't say that I've seen cardboard used that way.
I have, however, seen bailing wire used in numerous ways beyond the typical uses. Makes you feel better about yourself as a mechanic when you see stuff done that way! Junkyard , Aug 8, Joined: Jan 2, Messages: 2, Location: Australia.
I've used cardboard for gaskets plenty of times with good results, but you have to put at least a little bit of workmanship into them.
They're just ugly. Cmark , Aug 8, I guess I'm old enough that I've seen this done successfully many times. I was even taught how to use a small ball peen hammer to make these gaskets. Now you went and ripped it, if you'd been careful you could have reused em. Delmer , Aug 8, What is the preferred cardboard?
Cereal box? Parts box? Are Cat boxes the superior choice? Maybe Uhaul boxes? Medical supply boxes? Lol I couldn't resist. This music makes me want to pierce my eardrums with an ice pick! Off topic I know Junkayrd.

A lot of VW sump gaskets are like that. When you make a gasket from paper or cardboard you must treat it with sealant. A treated cardboard gasket works fine for the sump but a hard-paper gasket for the carb tends to ooze no matter what sealant you use.
To prevent this, buy a roll of resin- impregnated gasket material of the proper thickness. Good auto-parts places carry a wide variety of gasket material whereas the chain-store type of parts store many not even know what you're talking about. Commercially-made gaskets are usually better than anything you make yourself. They're accurately cut and use the right material except in the case of those sump gaskets I mentioned earlier.
And commercially-made gaskets are usually inexpensive -- certainly less trouble than making your own. When you buy a gasket, smile at the man and ask for two. Go on; he'll think you've got a whole shop full of engines back at the house. When you get home, write down what the gasket is for and the date, right there on the gasket itself. Then put it in your gasket basket. Or gasket book. Or hang it up someplace out of the way maybe over there with that collection of fan belts , because the next time you need that particular gasket the kid behind the parts counter is liable to frown and say "Did you say an AIR COOLED Volkswagen?
They sell some great gasket sealants nowadays; as tough as RTV but in a spray-can. Marvelous stuff. Makes your bug forget how to drip. Historically, gaskets were sealed with just about anything that came to hand, like tallow. Or beeswax. I don't know what kind of soap they used but the gasket surface was often corroded by the time I got to see it. The usual stuff was heavy grease. Or soaking the gasket in oil.
Some called for painting the gasket with Gasket Shellac! I'll bet you've wondered why they called it that. Gasket shellac was just that; a thick, gooey shellac. And like all shellacs, the vehicle ie, the stuff that made it fluid was alcohol. Gasket shellac was the stuff that resisted gasoline; you used it on gaskets and washers that came into contact with gas.
Peeling a page from the shellac idea, I've made successful gaskets using urethane varnish as a sealant. No, I won't tell you where I used them. But they worked. Different paints might do the job for you. Or even water. We usta soak cork gaskets in water before torquing them down. It seemed to keep them from tearing. You'd come along later, re-torque them.
A gasket's job is to make a leak-free joint between two surfaces. Unless the parts are polished like a mirror, their surfaces have tool marks that form channels large enough to pass molecules of oil, gas, water, air, steam The gasket is compressed into those microscopic grooves and seals them.
In theory, the best gasket is none at all; parts so slick they stick together like Jo blocks. Nowadays, what with numerically controlled tools and other innovations, we are blessed with machined surfaces so finely finished that paper gaskets may not be necessary, a coating of sealant is enough to provide a leak- free joint.
But as a general rule, if the joint was fitted with a gasket, use a new gasket on reassembly. I don't know who showed me how to make gaskets, probably my grandfather; maybe my dad. Us kids would be standing around, watching somebody work on something and they would hand us a part and say 'Go make me a gasket for this. Use the red stuff,' and we'd take the part and go make a gasket.
A child's chore; something given to the youngest apprentice. Like cleaning parts. Coming home from Baja, Jaysie and I were 'way the hellangone south of the line, out on that long empty stretch between Ciudad Insurgentes and Huatamote, and there's this big Ford camper, blowing steam.
Older couple. Oregon plates. BIG camper. In Baja you stop to help and there was already some folks there but their English was worse than my Spanish and the feller in the camper didn't know if they were trying to steal his engine or fix it. Thing was, he'd blown a gasket on his water pump. A gasket should be assembled, then exposed to heat and fluid. A used gasket already having swelling due to the fluids should not be reused. Do not reuse them.
Gaskets seal by crushing. Once in a while, the gasket, even while looking completely good, will still leak. The gaskets are designed to be crush gaskets though and are meant for single use. Personally, I replace mine each time I take the headers off. Yes you should put in new gaskets for your exhaust system. If you do not replace the gaskets there is the potential that the old gasket will leak and cause exhaust noise. While steel or other hard metals may appear more durable, copper is an ideal material for your custom-made exhaust gasket.
Its unique properties allow it to create a tighter seal that conforms to any surface and reduce excess movement. It is durable to withstand high levels of wear and it resists corrosion. You could reuse them, if you think they look good, but your chances of one breaking later have gone up now. I replace them every time, just heat the area around the studs, and melt a candle or crayon into the threads, let cool, they should come out easy, may need to heat again. Can I use cardboard as a gasket?
Can I make my own gaskets? Can I use gasket maker instead of a gasket? Should you Oil paper gaskets? Can silicone be used as a gasket? What is the best gasket sealant? Does oil pan gasket need sealant? Can I reuse my oil pan gasket?
