So yesterday was driving and my car started making this clunking noise, was like wtf, then a few miles later engine just seized up.. wouldnt start up again so had to get it tow'd home. Later when it cooled down i put some more gas in it, hooked it up to a battery charger and started it up.. heres what it sounded like before it hit operating temps and seized up again
