Ok, so fishing it out has proved fruitless, I've tried all methods, and getting something around that bend into the bore isn't working.

Given location, I can't get fancy tools, compressors etc there.

Please vote as above. I will count the votes, and go with the Majority.

[sassanach]

which cylinder is it in?

[JamesV6CDX]

Passenger side, middle one.

Send me your email addy, I owe you some cash!

let it burn baby burn

Can you see this elusive bit of rubber? Or are your cams/engine still locked preventing you from turning the engine? You sure it actually went down the bore? It'd be a bloody good shot if it did go down, I bet you'd never manage to deliberately throw owt down there.    
I'd turn the engine over by hand first, and then start it up. It'd make it a very very expensive bit of rubber if you'd to remove the head. If you did one, I'm sure that you'd then want to do t'other - just to keep things equal!

If you time up the engine can you turn the crank over without anything binding?

Just wondering if doing this will move the object into the centre of the piston where the spark plug hole is. Or whether the rubber is pliable enough to get squashed at TDC without causing damage.

You really need to find someone with an endoscope. 8-)

I had a similar issue on an engine I'd just rebuilt once. Metal cap from my dial gauge fell off and dropped into a pot just as I was setting the timing up. Took about 2 hours with a "grabber" tool but I got it out. You can spend a long time doing this sort of thing before it becomes anything like as much hassle as a head-off.

Cylinder was vertical, unlike on the v6, which helped.

Vote is 15 - 2 to let it burn at the mo. I am 1 of the 2

Your legal predicament adds weight to the "let it burn" argument.

I can only repeat my former comment. Turn it over with a spanner first!

[Elite Pete]

Burn it.

Voted James to burn the bugger !!!

The questions in my mind are:

1) Will the rubber bit get forced out into the combustion chamber area by a rising piston or will it get trapped in the "squish" area of the cylinder where there is very little clearance at TDC?
2) Is the rubber soft enough to just "squish" down if it gets wedged here, or will it generate enough force that something gets damaged?

All depends on the size and nature of the rubber bit and the combustion chamber shape. :-/

If it starts without damage the rubber will very soon become harmless as it melts. It's the first few turns of the crank that'd worry me.

Turning it over first by hand, then on the starter (with plug out, just in case it flies out of the hole) would be a very good move IMHO.

i would turn over by hand a few times.....

[Ian_D]

How big is the rubber? and where is it from?

If its managed to get passed the valve, then it cant be that big?

Will it fit out of the spark plug hole? If so, just start her up with the plug out and watch the bit of rubber fly out! Failing that... BURN IT!  

[Omegatoy]

ok heres my take on this, first off it wont burn immediately so will be in there bouncing up and down a couple of times minimum, second just suppose it gets sent out of the exhaust valve route, imagine what happens if it gets caught between the fast moving valve and  the valve seat, it will probably bend the valve or worse hold the valve open while the piston comes up to meet it!!so i dont think i would be starting it all with it in there, are you absolutley sure it did go in the plug hole? it would have to be a very lucvky shot indeed, and if you cant feel it in there i would guess it didnt actualy go in??
just my opinion James hope it gives you food for thought?
