Clip from 308 plug extender dropped next to plug HELP!!!

I am changing my plugs and when I pulled the extender off and the clip wasn't there. It is on the front bank so I got a mirror and a flashlight and I can barely see it NO ON THE PLUG . I've tried getting it with a magnet, blowing it out with air, blowing it into a position so I can get it with a magnet but none is working. I'm waiting on a mini shop vac from a friend to try that but if that doesn't work this is what i'm wondering. If I pull the plug and it falls into the cylinder can I fish it out with a magnet? I've looked and the area around the plug is very clean so I wouldn't be worried about dirt. Has anyone ever had this problem or have a suggestion on how to go about it? My friend just pulled up so I'll let you know how the mini shop vac works. Please help!!! Thanks in advance.

 

I'm not sure if the shop vac worked or not. I now can't see nor find the clip. The shop vac was empty still looking...nervous about pulling plug but I don't see how it could hide in the tube especially when spraying air into the tube 15-20 times. I'm thinking I may have now blown it out with air and it has fallen into they engine bay somewhere. I've looked under the car. I'll update when I can but still need advice on if I should pull the plug or not.

 

The good thing is I know it isn't in the carb throat...my airbox is still on. I originally saw it in the tube with a mirror and light but can't see it anymore so I'm almost convinced it is stuck somewhere in the engine bay. I'm going to go ahead and carefully fish around the bottom on the cylinder with a telescopic magnet for a pull or two to see if I get lucky...If not I'll order one of those scopes I can think of a million and one uses for it...I'm sure I can get one on ebay or something. I do know i'm not going to rush and be sure I find it just for peice of mind. I'll forget I dropped it and if it is in the tube next time I change my plugs I'll get a nice 10k parts bill to fix it. I'll keep everyone updated.

 

I'm sure it was the clip. After trying to find it again blowing air in the tube etc. I still couldn't see it. I loosened up the plug thinking it was perhaps lodged underneath the nut of the plug somehow. Still couldn't find it. I went ahead and pulled the plug after about 2 hours of searching around the bottom of the car and the engine bay. I pulled another clip out of one of the extenders and did a size comparison with the threads and found it could fit but would have a good chance of hanging up. I already ordered a boroscope and put the plug back in to keep dirt out. I'll wait til the scope comes in and check the cylinder just for peace of mind...it's not worth the parts bill. Unfortunatley if it gets under the nut of the plug duct tape and a claw won't work...You can't even get a magnet far enough down unless it's really small. Thanks for all the suggestions I'll let everyone know what happens when I get the scope.

 

oh and it is magnetic...I checked...but the rest of the extender metal isn't.

 

I did back the plug out and do all of that again...I even removed the shop vac filter and covered it with a screen to increase suction even more...gave my hand one hell of a hicky. I modified a hose with a bench grinder to fit in the hole perfectly. I'm pretty confident it's not in there but I'd still feel better if I found it. I'll be sure to let it run for a second and stop it pull the plug again and make sure there isn't any mechanical damage...then I'll know it's not in there.

 

My scope came first thing this morning and I couldn't see the clip in the cylinder...I had to get the 4mm scope to get inside the hole which of course was 3 times as expensive. Neat tool though I'm sure I'll use it alot. I did talk to a well known engine builder in town that owns alot of high end cars last night. He said 98% of the time when something small like that clip i'm looking for falls into the cylinder it will just get blown out the exhaust valve within a couple of strokes. Normally I wouldn't believe something like this but I've known this guy since I was a kid and he's built 1000s of engines and about 95 cars from scratch in his lifetime.
