WHAT TO DO WHEN ERASER AND CAP ARE CAUGHT IN CYLINDER

Hello eveyone,....

Anyone who's been following my project knows the hell I've been going through. I finally got the valve issue sorted out and now have good compression. And I bought the new set of cables for the batter which got the starter going again....

Heres my current problem... What do you do when your father gets a pencil eraser and metal cap stuck in the number one cylinder of your engine. Yes,... thats right,... he put a pencil in my engine to see the piston rising and when he pulled it out not only the pencil eraser but the metal part that holds the eraser to the pencil fell into the cylinder. I have been trying with the shop vac for days to get the eraser out with no luck. If I have to pull the head again after all I've been through I think I'm going to kill him. What should I do. Is there any way of getting it out without taking off the head. What would the results be of starting the engine,... considering the rubber would probably burn up,... what about the metal.... Please help,... I really want to just get this nightmare over with. Thanks,....

Dan

hopefully the metal is ferrous and a small magnetic pick up tool will get it. OR maybe some kind of sticky goo on a stiff wire. good luck

Try taping a piece of fairly thin hose to the end of your shop vac and insert it thru the plug hole and fish around a while - might get lucky. About a foot or two of that clear plastic 1/4" tubing sold at hardware stores should work. The eraser is probably on the piston towards the outside of the block, so you'll want to feed the tubing so it bends in that direction.

Do yourself a favor AND tear her down AND do it right AND hug the old man for trying to help!!

He won't be around forever AND when he is gone, you will think back on this and first cuss, then laugh AND then wish he was still around!!

Sure wished my Dad had stayed around longer, but he left us at age 45 when I was just a young 14 year old punk kid.. Mom left us last year at age 82 AND I sure miss her.

Yea,... Your right,... I can't stay mad at him,... I'm not really that upset anyway,... Its just that this has been the project from hell... He was trying to help and I needed all the help I could get.... Ill try blowing out the motor and such and if I can't get it out then ill pull the head again.... It happens,... Thanks again for the help,

try a good strong vacumn cleaner.

I second what RobertG said,If your air blower doesn't have a long nozzle you can use a piece of 3/16 brake line tubing as an extension.If the air pressure is high enough and the valves are closed it has to come out.One of those flexible pincher tools may also work.

I dont know if it will fit into a spark plug hole, but I bought a neat little flexible shaft tool with a light and magnet at the end( for fishing a vavle cover washer out of an oil pan!). IF the piston is at TDC, you should be able to fish it out of there

Take a length of 1/8 copper tubing,& put a small bundle of ductape on the end if it & go fishing.
MAKE SURE the tubing is clean so the tape sticks good,& MAKE SURE the little wad of tape will clear the spark plug threads.I'll try anything once

Ah the heck with it,,pull the head & buy your Pops a new pencil(with no eraser) :rolleyes:

Start it and it will blow out or burn up, it's soft so it wont hurt anything. HTH.

That's a real drag, you'd have to pull the head just for that little thing, have fun. I don't think it would do any damage in there but I'd hate to chance it on a rebuilt motor.

Move the piston to BDC it will be easier to get the eraser out. DO NOT START the engine with it in there, it can get caught in the valve seat and really do some damage. Think new head, valves, piston and rod. If your lucky the block will be okay.
With the piston at TDC you will never get it out because it has fallen at an angle you cannot get at. Just move to BDC and use the "plastic magnet" or adapt the smaller hose to the shop vac. Fish around and get it out!

Yes, turn the engine by hand so the piston moves down. That will get you a little more breathing room in there to fish it out. It should fall to the outside of the cylinder.

If that doesn't work tear it down. Don't start it up with the plug out - too risky with the metal piece IMO.

If you can see/touch it... STAB it. A pointed coathanger (cut it diagonally) will probably do the trick.

If that fails, I doubt that the little sucker will do anything to your motor if should you decide to fire it. A wafer thin piece of soft aluminum, and a gummy piece of rubber. I'd fire it before pulling off the head, but it's your motor...

Fire it up the eraser and cap won't be there after the first revolution. About 25 years ago I sucked the linkage arm for the secondary air flap on a Thermoquad into a 340 engine in a Duster. When I heard the sound of something bouncing on the piston I shut off the engine and towed the car home. I again started it up briefly to determine which head to pull and after pulling the head I discovered that less than 1/4 inch of the 2 1/2 inch long rod was left. There were a couple of very little dings in the top the piston nothing serious and hardly visible without looking real close. I wished I had let it run for another 30 seconds it would have saved me a lot of work. Now this was with a steel linkage rod, much harder and larger than the pencil eraser.

Honestly man, its a couple of bolts. I know its a pain in the ass, but live and learn. Just hope you used the reusable steel head gaskets, and make sure to use the reverse torque down proceedure when taking the head off.

P.S. Let us know what happends!

If it makes you feel better I just spent 7hrs trying to get my damn license plate on. :D
You're supposed to put the car in park before you try to do that. :D

After you fished, poked, cussed, looked, vac'd and if it's still not out take out all the spark plugs, remover the coil wire, back off the rockers of the cylinder with the eraser so they don't open. Turn the engine over with the starter, there should be enough velocity to spit that eraser right out of the spark plug hole.
Go to the doctor to have your eye looked at because you wanted to "see" it come out.

Pencil, 10 cents.
Gaskets, $30.
Story about when your Dad shoved a pencil in a hole it didn't belong....priceless.

:D

Years ago when I worked as a mechanic, a guy came into the garage with an engine knock. Seems his choke stuck and the only thing he had in his pocket to hold the choke open was his house key. :eek: Well, the car started and the key went through the carb, an intake valve and into a cylinder. Made a hell of a racket. We fired the car up, drove it inside and pulled off the head that had the mashed plug. When we got the head off there was no sign of the key. The top of the piston and the combustion chamber were coated with brass, but there was no key anywhere. Only thing we could figure was that when the key got beat up enough it went out through the exhaust valve. You think that eraser is tougher than a brass key?
