One MAJORLY unmentioned thing...

Remove the studs from the intake and get shorter studs. Memory fails me as to how short. But about 1/2"-3/4" shorter than the old ones. Trust me you will save a lot of time and get a better seal to the intake.

One word.. Vacuum Leak.

Look for all the fittings and make sure ones not unplugged. Especially the one on the manifold behind the carb between the carb and the head.

What I have done to get a good seal is this combination:

1 - 1/8" Thick "fluffy" Paper Gasket
1b - Indian Head Shellac or Aircraft assembly glue (both at local auto stores)
2 - 1/4" Thick Felpro gasket with the nylon washers (Pinto gasket)
2b - Indian Head Shellac or Aircraft assembly glue (both at local auto stores)
3 - 1/8" Thick "fluffy" Paper Gasket

Those that only use the thin gaskets don't have enough material to get a good seal if you should have a slighty unsquare Weber bottom or intake face.

The thick Ford gasket, has those nylon washers that can keep you from tightening good enough for a perfect seal.

Using the three in combination give you a real tight seal and enough material to lock down the nuts and never have to worry again.

As for Jareds choice of using Bolts, thats not a bad option, but if you get them too long (but not so long you don't notice they are bottoming out). You can think you have everything tight and have leaks, so error on the side of being a little short. Its vital to use washers and lock washers. Also they also tend to back out more often than the studs/nut combination. So be sure to check thier tightness every so often and you may want to use a little low strength lock-tite.

Some cut the bottom of the snorkle flange and trim the solex adapter flange. Some have even designed a hold down, etc... Hopefully someone will come to the rescue soon. Being a Manta person I am not familiar with excatly how it is fixed. But it can be.

That adapter works on the earlier intakes, but the later intakes are taller. Which for performance issues is better, but for clearance issues is a problem on the GT.

What about NO is not understood!!!

Reasons, complete with pics, already addressed in another 32/36 thread here!

Hmm... someone using too much? I have NEVER had a problem. Indian head works great.

But too much of a good thing can be a bad thing.

Also I glue the assembly together and let it get really tacky and use it in a very very thin application to both sides of the gaskets.

I have used the thin weber/Pinto/thin weber combination on 6 cars, none have had a problem nor did they have a vaccum leak or thier carbs come loose. Also the thick pinto gasket provides a thermal buffer for the carb.

What the link "with pictures". Just curious to see what the person did.

Otto, I can't find any posts you mentioned.

Ahh... I see the problem.

Notice:

Carb - fluffy gasket - indian head - pinto gasket - indian head - fluffy gasket.

I use the sealer between the gaskets and not ON the carb.

1) Apply very thin so its transparent (Indian Head has the consistancy of sticky shoe polish)

2) Indian head drys' fast and hard, its not "gooey" like silicone or permatex.

3) Allow the gasket combo to dry before installing.

This gives a nice thick gasket that seals on both sides and gives the larger thermo break.

Usually at worse if the sealer squeezes out, is just barely noticable. and then drys hard virtually instantly.

As for the heat sheild, using the pinto gasket you can loose it. I have a 2.0L with a 40DGAV and no heat problems.

Go to an Advance Auto if you have one, they can usually get anything in 24 hours.

More info on that is in the Legere article on intakes. If its not here in the archives it is at the http://www.opel-na.com website in the tech library.

If you're pulling the intake it's a great time to port the intake. Hardest part will be removing the intake from the exhaust. Even then, you could do it attached to the exhaust if you removed the intake from the head, and blocked the holes in the head while you worked on the intake. Will leave a lot of little AL bits in the engine bay though. Clean them up before you put everything together.

Optimally you would put it on a bench to do the work.
