Exhaust studs

[Miskatonic]

Does anyone sell exhaust studs for the manifold? I hooked up the intake/exhaust manifold to the engine today and then spent a good half hour figuring out how to get the exhaust flanges to match up. After awhile I got to thinking that it would be a heck of a lot easier if I just had studs and nuts instead of bolts. I managed to get 4 out of the five bolt but had to use the old exhaust gasket since the one that came with the intake/exhaust manifold (felpro) was a square shaped 4 bolt, and mine has the rectangular flange with six bolts.

Is there more than one type of exhaust gasket for the GT?

Also, try this site www.ssstuds.com as this is where the studs are located.

Jarrell, do you know if the studs are available in 9mm?

Not likely. 9mm bolts are like hens teeth. If you are trying to stud your exhaust/ intake manifold I would recommend just tapping the holes out to a SAE thread and use some split-lock type bolts. I will be doing this on my next engine.

I think Miskatonic was talking about the exhaust manifold flange to head pipe bolts, which are 8mm and pretty easy to find. I get those studs and the copper or brass nuts for them at places that sell parts for air-cooled VW's usually, though I have seen the 8mm brass nuts for sale at my local Autozone in the "Help" section as well.

That gasket kit actually didn't come with the exhaust flange gasket, the square one that came with it was the one that goes between the intake and exhaust manifolds, which almost no one ever replaces. The flange gasket you have to buy seperatly.

Thanks guys ...
Yes, I was thinking intake/exhaust manifold studs ... they were fresh in my mind after spending too much time Sunday removing and reinstalling dual side drafts. You're right 9mm bolts/studs are practically non existent ... asking for them even at a fastener speciality place is always good for a laugh.

You DO know that later CIH engines used 9mm "Allen" type (socketed) intake/exhaust bolts, right? Much easier to remove and reinstall, IMO.

Otto ... I did not know that. Where can I find them?
Thanks ...

OGTS sells both new and used ones.

OGTS ... is shipping a set today.
Thanks!

Just wondering if the AD posted here is the same as the ones OGTS sells. The price is 22.00 on that site, yet OGTS has them for 3$ for a set? They are part #10011, and says "Bolts Exhaust Manifold to Head Pipe"

Any info on this? I've got to place another order with Opel GT Source anyway, and if they sell those studs, I would rather order from them. The head pipe IS the one that bolts to the stock exhaust manifold, correct?

Also.. does anyone know of any LOCAL place that would sell the studs and gasket? I really wanted to get my car goin in the next day or two.. but if I have to order offline.. it don't look like it would happen ..

Go to the "Help" brand section of any Napa, Autozone, etc, and look for "waterpump studs". They sell a set of four (so you'll need two sets to get six studs) that are the correct metric pitch and length. They cost $4 and even come with nuts and lockwashers, although you should probably get copper nuts instead.

I couldn't find any local place that had the header pipe gasket in stock.

Would I look for waterpump studs FOR an Opel GT? What is the size..length..thread pitch.. all that?

And I actually found the gasket. I did not know that it came with the head gasket set I purchased a while back!

Nope, it's just a generic "Help" set which I've found all over the place. Just look up the thread size and pitch on this site and match them up. Sorry, I can't recall what size offhand (M8?). I know them just by looking at them, and I think it's the only set with just four in the package, but I could be wrong there. They look exactly like the ones in the link you provided.

[tomking]

M8x1.25mmx however long you want.

[Sparky73]

Thanks guys! I'll head over to NAPA tomarrow and see what I come up with. What exactly is the point of a Copper nut for them? And what is a good length, or at least the Min. and Max. I can use?

They screw into the Exhaust Manifold, and then will just go through a hole in the head pipe correct? With the nuts tightened to head pipe?

Waterpump bolts are 7mm x 1.00 pitch. A true oddball, even in the metric world. And there are various different lengths of course...

These are stainless steel. Don't know if Gil's are SS or not.

[Sparky73]

Went to NAPA and got some! The guy there swore they did not even carry metric studs for a waterpump or an exhaust.. but when we went over and looked, the only packages of them they had, were the right size

Now if I only had a head pipe that wasnt all rusted..

Does anyone know if OGTS ships their items same day as your order, and do they ship 2 Day.. Next Day.. ect, instead of First Class and Priority? I know shipping price will be more.. but curious if they even do it.

I am going to give them a call tomarrow if nobody here has one they want to part with

HA! Told ya. Sneaky, huh?

I usually get my stuff from OGTS in a couple days from clear across the country. If you get your order in before 1pm PST, they will ship out the same day. They offer expedited service, too, in case you're in a pinch. I'm not sure whether that "holiday" next week will affect postal deliveries, though.
