Well.. After removing the 2b carburator off the '50 Commodore 6, I dropped the nut holding the carburator to the intake manifold. Can't find the nut. It could have fallen into the intake! Sent a strong magnet down the intake on a snake like probe, and picked up nothing. Should I remove the intake ? There's a chance of running into complications, doing this, so don't want to, unless there is no choice ! But don't want to ruin a perfect engine! It couldn't have been the beer that caused this!

Pull the manifolds , Ray and don't take a chance of bending/ breaking a valve or a piston.0

Murphy's Law: If it can fall into the intake, it DID fall into the intake. Pull it, an intake gasket is a lot cheaper than a piston and valves.

Ah yes, I forgot Murphy's law #1, " In the course of any endeavor, anything which can go wrong WILL go wrong "0

Fire it up, with any luck at all it will shoot out the exhaust pipe and you will be good to go.

Buy a telescoping magnet, there a couple bucks. It's worth a shot. By no means should you fire it up. If that nut gets caught it could cause major damage. Do you feel lucky? Well do ya?

Corollary to Murphy's Law - "A dropped part will always land where it can do most damage". Get a small variable angle mirror, available form any good parts and acessories store, and have a look. It won't have gone aywhere far from the intake. Good luck,

It's times just like this I find a need for a new tool...

You all know I do things the right way, and even on this one I'm saying pull the manifold. It is not worth the chance.0

Firing it up was a joke, before I took the manifold off though I would look on the crossmember and up against the manifold and head. If you didn't see it go into the manifold look every where else first, when you've exhausted all the other places then pull the manifold. Every time I think I've lost a nut or bolt it ends up on the floor after I fire the car up.

It is not guaranteed that the nut went into the intake. Think about it...after the nut came off, you dropped it. Meanwhile, the carburetor was likely still on the intake, and, if it has been on there a while, it was at least a little bit stuck to the manifold.
Therefore, how could the nut go into the intake, unless you were holding the nut as you wiggled the carb loose, and then, after fully removing the carb, you dropped the nut into the intake hole?
I would search very thoroughly around the car, and the floor, and the crossmembers, frame, etc, as mentioned by a previous poster, before I pulled the intake.0 -
I had the nuts and washers on the studs that hold the carburetor on when the carb was off for rebuilding. One nut fell off when when they were being taken off to reinstall the rebuilt carburetor ! Looks like the manifold will have to go off. Hope nothing snaps off on the removal ! Thanks for all the great advice!0

Maybe as a last ditch effort to prevent having to remove the manifold, you could hook up a good strong shop vac to the areas the nut might have fallen, and the magnet won't quite reach. Can't hurt anything, probably worth a try. Just start with a clean canister so you can determine if you actually got the nut or not.0 -
That is a really good idea ! Never thought of it! Have a powerful shop -vac, but the opening for the intake is small and has lots of curves. The Shop -vac hose is quite large. Pretty sure the nut fell in the intake opening closest the head.0

If your hose is2-1/2" diameter maybe you could use the1-1/4 hose that fits the vacuum. I have both for mine and I have a 1-1/4' hose that is quite flexible right to the end. (it doesn't have that riged end on it.) or maybe you could find something to adapt down to size. Sounds like a decent Idea if it can be implemented. Good Luck!!!

Well,took off all the nuts of the intake manifold. Looks like it's attached to the exhaust manifold. So took off the wheel and the inner fender cover to get to it better. Can get to most of the exhaust manifold nuts to the right of the carburator, but not the left. Very hard to fit a wrench in there, must be a better way ! What a costly mistake for dropping one little nut !0
-
also be sure to keep a couple nuts on the topside while you work the bottom row so you dont break the ears off the exhaust by letting the set of manifolds tip away from the block under their weight0
-
If you know anyone that works with wood and has a portable sawdust vacume/blower they have FAR-FAR more suction than the best of shop vacs. My 5hp one will just about yank your skin off!! If it would'nt pull it out even tho some valves are open it ain't there. Just seal it with duct tape at the carb mount and turn it on.0
-
Update: Tried the vacuum, great noble idea, but nothing retreived. Good advice, worth a try, thanks! Even tried a 'snake' with a magnet attached! Have all the nuts off the intake manifold. The exhaust manifold, most are off. Several can't come off all the way because they are now hitting the exhaust manifold and won't go any further! Now what? Ken U, I had no Pilsner Urquell on hand, but had several Olympia's! That helped! So whoever did this task before, I need your advice!
Epilogue: Always stick a rag in any opening where you are working with nuts and bolts!0 -
Okay;
here is what I found with my Hornet, you have to back those nuts out a little and move the manifold then back them out more and move it a little more. The real pain is putting them back on, you have to get the manifold up and then start the nuts, not an easy task on the Hash because even though it sits low to the ground the fenders are really high. By the time you get those nuts on your ribs will feel like you've been kicked a few times and you will be able to get a side job as a contortionist. I still don't think the nut fell into the hole but you have to change gaskets anyway so finish taking it apart.

Just got the intake manifold off, and viola! The nut was there in #2 ! Glad I did this! Now the manifold will be wire brushed and painted, and a new gasket put on. This is a narrow block 262. Is the intake gasket the same as for the other 6 engines?0

Butterfinger "R", I don't know the answer, but I know you are glad that you looked for "NUT" . Take care my friend. See you at the W'trn meet in MAY?? VicTor Z0

I was sure wrong on that one but I'm glad you found it.

Glad it worked out Ray. The previous owner of my '56 Dodge CRL dropped a couple screws down the throat and then started it up, of course, scoring 2 cylinders. Fortunately, a 0.030 over bore will clean it up.0

Ok, now the instalation part. Have all new gaskets on. Tried to install with both intake and exhaust manifold together, but couldn't line up the studs with the bottom exhaust manifold holes. Took the intake manifold off, and the exhaust manifold lined up perfectly. Started the nuts on the exhaust manifold ( Not real tight), and now tried to install the intake manifold. Won't Work ! Now the intake won't reach the studs ! Any one know the exact procedure to do this, so the studs can line up with the holes ? Do you install both manifolds together attached, or one at a time? Then I can figure out how to put the nuts on once its lined up. Only beer drinking when its finished!0

Ya gotta put em together loose, don't tighten the two manifolds up, once you have everything on the car tighten up the two manifolds then tighten up your manifold bolts.

Glad to hear that you found the nut. Reassemble and it's good to go.

Ray,
Sorry I didn't read the forum sooner! I just saw your dilemma. What we have used before when a nut or other metallic object drops through a carburetor or into an intake manifold is removing the spark plugs one at a time and attaching an air chuck with 150 lbs pressure to them one by one. Rotate the engine slowly until the exhaust valve is closed and the intake is open. This will cause the high pressure air to exhaust through the intake manifold and carburetor. You will want to have a strong magnet down the carburetor or intake manifold port to catch and hold the nut. Proceed down the spark plugs one at a time until you capture the foreign object. Its worked several times for us over the past 35 years, saving time and expense.

Thanks, John I'll save that advice ! Hopefully there won't be a next time, as there will be rag stuffed in every opening ! Now comes the reassembly.0
