Rebuild that bish go get a FSM everything goes together the way it came apart just torque to spec. Replacing the motor is a short cut but its just water locked take it apart find out if the sleeve is broke witch is most likely happened then go buy a new block or take it to the machine shop if its salvagable. Buying used motors is for newbs with bolt on skillz. Bring the term "Built not bought" back brotha not to mention it will run alot better rebuilt it be bran new

Or be like every other grandma in america and buy a used motor with 150k miles on it and spend 3 times as much as a rebuild for somthing thats prolly about to blow up.
