If I remember correctly,in TWOK, Spock enters the reactor room. The pedestal contains the DiLithium crystals. He must have reoriented the crystals.
You can't check the oil or jumpstart the battery in an automobile flailing around as clumsily as Spock did in that scene. Yet you suggest that Nimoy's plausibly miming some kind of emergency maintenance on an FTL engineering system.
That's the worst kind of excuse making.
