You might consider this a "nervous energy" or "fraidy cat" question:


If the piston for the cylinder you are working on is locked at TDC. Is there enough room in the compression chamber for the valve to actually (irretrievably) drop into the cylinder? Or will it fall onto the top of the piston with enough of the stem still exposed to be gripped and retrieved?

The reason I ask is that I do have an air compressor and I am thinking of doing the job using it vs. the "rope (or bungy) trick." Only thing is I am looking for any reassurance that if I did bump the valve being held by air pressure (or if the air pressure failed for whatever reason) and dropped the valve, that I can still retrieve it. If not, then I think I would prefer the assurance of a mechanical block (AKA rope).
