I know the FSM says replace if not in spec. But AFAIK if it hasn't been overheated it may still be within spec for flatness, depending on how many heat cycles its been through. Moreover, I might go out on a limb and say the FSM has been shown to be imperfect and in some respects, open to...
I'm not convinced the charging infrastructure will be able to keep up with a surge in EV ownership. Of course I could be wrong, but the jury's out on that. Keep in mind, even if supercharging only takes 3x the time as an ICE fill up, that still translates ot a lot of cumulative delay if everyone...
Granted I'm no expert, but I don't see why a head couldn't be reused if a reputable machine shop pressure tested, reshimmed the valves, and checked it for flatness, etc.
There may be cases of the heads being warped/cracked beyond repair, but it's difficult to say how common that actually is...
I don’t mean to derail the thread, but I seriously doubt that’s going to happen in our lifetimes. The battery tech and charging infrastructure is nowhere near there for EVs. Same thing for hydrogen. Not to mention any decent EV is at least 30k. I know this will all improve eventually, but who...
