1800 Intake Manifold Myth!

[spiderman2000]

Don't give up ! I did this about 3 months ago or so..... Best thing I ever did for the car. I would recommend removing the carb before completely removing the intake. There is just enough room to take the intake off without removing any of the master/booster parts.

Just take a deep breathe and step away from the car for a bit. You will find when you return to it things will be alot easier.

Hi mike,
I just realized the two centers came off because they were actually bolts instead of studs. Where can I get two more studs? Will an auto parts store have them?

Brady,

Some cars have bolts, all of the two liters I've see/taken apart have only two studs holding the manifold and the rest bolts. I would not worry about it. I lightly coat each bolt with permatex gasket maker to seal the threads and prevent rust.

studs or bolts, your preference... i was making sure that the count was correct .. six not four. that center section would leak like a busted dam without those center fasteners.

Sounds good guys! Thanks

i just looked... mcmaster carr has metric studs

i was looking for brass exhaust manifold nuts, which i've yet to find... but they got the studs

How many do you need? I have a ton of them.

I'm glad everyone is talking about studs and bolts because I too have a question about them. First, yes, I did finally get the manifold off. But, their were MAJOR clearing issues with the brake booster. I don't know how you guy get them off. I had to reach in with a pair of pliers and remove all the mounting studs to get the manifold off. So, no way is the new 1800 going back in with the studs. I have already tried to test fit it and it won't fit. Someone said something about only 2 studs on the 2000 and the rest bolts. That would make a lot of sence. Also, what is that thing right directly under the manifold and above the fuel pump (and how do I go about getting new hoses for it - both sides)? That is another thing that was not allowing the manifold to come off (nor letting the new one go on for that matter). Add the altinator bracket and you have the trifecta of NOT COMMING OFF. Anyway, what type of bolts should I get as I am not going to use all the studs again besides one fell down inside the crossmember. I seem to have a lot of luck with that type of thing.

Another question, It's a good thing I started this whole thing because I noticed that the freeze plug was starting to leak. I know I need to really flush the motor but what size do I need get to replace that F Plug?

Finally, and I know I should start a new string for this but, what do I need to do next to fit the 1800 manifold onto the 2000 motor? And what do I use to plug the large holes on the inderside of said manifold?

Wow, that's kind a lot huh! Thanks!

Katsi,
If you want, I'll trade you the two bolts I have that goes in the middle for two studs and nuts that go with them. Just look at my pic I gave you on the first page and you'll see the ones I'm missing. Let me know.

That's a separator that acts like a pcv system. It's a good idea to change the hoses while you can actually see it.

i believe the correct name is a cylonic trap, and it vents the crankcase, while filtering out most of the oil vapor back to the sump. new hoses are readily available from our catalogue suppliers. might also want to consider the brass flame trap that helps guard against an unruly backfire.

dunno what's so difficult about removing that manifold. once the fasteners are out, i have never had a clearance issue. the last time around, i even left the carb on the manifold wilst swapping. and, i have never removed the studs from the head, just take the nuts off the studs.

that top alternator bracket should have been a breeze to set aside.

a magnet on a stick works great for removing nearly everything from that x-member. you might even find some sockets left there by the previous owner... i did.

when you put an 1800 intake on that 2 litre engine, you will discover that there is no place to mount the top of the dipstick tube. you will either need to create your own bracket for the top of that tube, or obtain a tube from a fuel injected car and install that.

if you have not addressed the exhaust gas feed from the other side of the car, now will be the time to consider what to do about that.

the holes left by the sensors and switches onthe 1800 manifold can be plugged with metric oil pan plugs found at any parts store.

[katsi]

UHHHHH!What is the "exhaust gas feed from the other side of the car?" Also, is their any literature on swapping this out manifold? Thier are a lot of exposed areas in the head. For example, towards the front of the motor, their is an area that is compleetly exposed and not covered by the 1800 manifold. I think it goes to the large smog pump or whatever (BIG ROUNG THING) that sits next to the carb. Also, their is a small bump with a tiny hole in it on the 1800 manifold that does not line up with the head of a 2000. Instead, that small hole thing is flat on the 2000 manifold.

Man, everyone at the Fiat meeting said "oh sure, the 1800 manifold just bolts right up to the 2000" - NOT!

I know I'll get through this and I appreciate all your help and advice.
