Re: D'oh! Dropped something into the cylinder..
I have worked on diesels for about 25 years but mostly HD diesels in earth movers and big trucks. However, fishing a small piece of metal out is common to any engine.
The hole size is quite small, is it about 1/4 to 5/16 in size ? Do you have a small magnetic that will fit down the injector hole ? If not, can you rig up a vacuum set up and apply suction over the hole. Now, I do not have a book to see the cyl. head construction. I assume that you have a small chamber that serves as the pre-combustion chamber to preheat. This small area serves to build up heat .. to aid in starting the engine and also proper burning of the fuel. Most likely, the small bit of cable dropped all the way down into the cyl. and is laying on the top of the piston.
If the piece is longer than the diameter of the hole, this will make it much more difficult to remove. You can carefully bring the piston up to the top of the cyl. DO Not Bring it all the way up, if you do, you will force the small bit into the top of the head surface or piston top and this will not be good. You will have to tear the engine apart to get the piece out.
How to tell if you are about to top out in the cyl. Depending on the head design, you may be able to use a 8 or 10 inch ty-rap to locate the piston top. Turn the engine over very slowly (with ratchet) to bring the piston up to about 1 to 1/2 inch from the top. Your doing this to increase your chances of getting the piece back out.
See how you make out, start with small flex magnetic and then to vac. house over the hole.
