So the other day i go to start my car and it makes a big clunk like the starter cant push the motor. So i start reading and see the motor may be hydrolocked. So i try turning it w/ a breaker bar, it will only go one way and stops at the same point on the way back. Soooooo, i started pulling plugs one by one and turning the motor over again, when i get to #4 i pulled the plug and coolant came pouring out . Greeeeeat, now i get to pull the head off and replace it. Just venting....
