Frank 157 Posted March 31, 2023 Share Posted March 31, 2023 Replacing perkins 4108 Air Filter, dropped the capping wing nut down the intake, accident waiting to happen and it did. I tried magnets on wires etc to no avail I guess the next stage is to take the manifold off but what are the chances it has gone further and the head has to come off ? I suppose its about he dia of a 20 cent piece maybe bigger. Any engine gurus out there I would appreciate your help , even if it is not want I want to hear, bloody Murphy has been a constant companion lately F**k it. Quote Link to post Share on other sites
Psyche 709 Posted March 31, 2023 Share Posted March 31, 2023 Highly unlikely to go into a cylinder, Id keep trying with a magnet or just take the manifold of- its not that hard. Quote Link to post Share on other sites

Thanks, that's what I wanted to hear, I think the wing nut is SS so not magnetic. Quote Link to post Share on other sites
BNG 49 Posted April 1, 2023 Share Posted April 1, 2023 Stick some flexible rubber fuel line up your vacuum cleaner nozzle, lots of black tape to seal and you have a flexible vacuum probe. 5 Quote Link to post Share on other sites
ynot 52 Posted April 1, 2023 Share Posted April 1, 2023 Usb endiscope... Pb tech 50 dollar ish... plug into phone have a look first just in case one wing happens to be sitting half in valve seat on open valve.... Then ya know what to do. Don't fiddle poke prod untill ya know.... If ya find it sitting by a open valve where it's sitting... Wind motor till valve closed whilst watching with camera then make a plan to poke prod hook fiddle or remove manifold. Murphy is at play here so eliminate Murphy Quote Link to post Share on other sites
Frank 157 Posted April 1, 2023 Author Share Posted April 1, 2023 Thanks all, I made a vacuum tube as described and tested it on a spare wing nut, it easily latched on from any angle so long as it got within 2 or 3 mm however after many attempts fishing around with it I came up zero so I looked around the engine itself which is in tight space and found it by feel tucked into a groove between the engine bed and the compartment sidewall. I assumed it had gone down the intake but seemingly not. Now I just have to figure if it is the correct one or another that was lost by a previous owner, I might get a USB camera today as a final check before starting the engine. I heard Murphy muttering he will get me next time. 1 Quote Link to post Share on other sites
harrytom 671 Posted April 1, 2023 Share Posted April 1, 2023 . remove intake as others have said, Peace of mind. Yesterday changing engine mount on the boys Saab, thought the nuts had disappeared in to the chassis rails, odd ball size and imperil., but after a search found them. Not where one would of thought directly underneath but about 2m away on the driveway.17mm socket nut but 3/8 threads. Quote Link to post Share on other sites
Frank 157 Posted April 2, 2023 Author Share Posted April 2, 2023 Ya gotta love imperial and metric mixes, camera worked well and showed all clear, have since run the motor and all good, yes its unreal how far a dropped fastener can travel. 1 Quote Link to post Share on other sites

Not all SS's are non magnetic, depends on the application and manufacturer and the accountant. Quote Link to post Share on other sites

Great innovators (turbo, fwd, and the funky ignition-key-in-the-centre-console thing) but very British in that stuff broke all the time or didn't work and oil leaked everywhere... Made planes that weren't great too. Quote Link to post Share on other sites
