Well... if you are piercing your cartilage, you won't hit a vein. On other places it is possible to hit a vein, and if it's major, you could bleed to death... But I'd imagine you'd get help before that happened. ^^^^^ You CAN hit a vein, but not ALL of your blood is in your ears. So I HIGHLY doubt if you perhaps did hit a vein, that you could bleed to death. None the less you may bleed a lot though. It truly depends on if your a bleeder, or not!
it would hurt
when you hit the blood vein
Unlikely, although hitting a vein does increase the chance of an infection.
It depends where but if you hit any artery or vein it is a problem.
hit somebody... hard zero lash means no play you must be refering to valve adjustments
Doing it slowly may help
the valve bent because the piston hit it, due to a weak valve spring or over revving the engine
You'll hit the vein and they'll bleed to death.
you could break the valve on intake or exhaust stroke top of piston could hit it
Technically no, but I have seen valve hit valve when the timing belt breaks.
if you miss it will burn bad, so quit an then hit another vein an if it burns then jus squirt it in your mouth if blood is all in your syringe
