I have never had the plunger to fail to reseat (either by playing with it uninstalled OR when you remove the protective cap ie oil running out)..
The protective cap also contains an 'O' ring, so even if the plunger fails to seat fully, as long as the cap is on securely you wont loose any oil.. One thing you could do, but I never even thought of it until you mentioned it was to make sure the plunger by pushing up on it after the drain is complete to make sure it drops fully down.
I know A LOT of ppl love the Fumoto valves, but the possibility of the lever getting repositioned bothers me.. You can get get those small squeeze hose clamps to secure the lever, but im still uneasy about it.. Especially on something like my tractor that would have a great possibility of running over brush etc.
I have an uninstalled valve if anyone would want to see it, I can take pics and post them..
Just my thoughts..
