I’m practicing for my driving licence and I’m going to driving school, just out of curiosity though I’ve looking on YouTube how to start and run a car and I’ve seen at least 3 different methods, I dunno which one is the correct. Things like the order when you release a pedal or when you need to press the clutch keep switching…
Ah, like this?
The key there is to double-check that all your lug nuts are tight (let alone installed at all, LOL!) when you swap from your street wheels to your autocross wheels, and vice-versa.
Same goes for your motor mount bolts if your engine fell out, I suppose!
(In all seriousness, though, nothing you can do just trying to drive stick is capable of launching the engine out of the car. The worst-case scenario, aside from losing control and causing a wreck, is a money shift – accidentally downshifting to too low a gear and over-revving the engine – but even if it managed to blow a hole in your engine block, the bulk of the thing would largely stay within the engine compartment.)
