When you're taking the bottom end apart, don't have any alcohol around, you don't want to make any mistakes there
At least pull the motor out and take it apart. Have a look see how much damage you've done. You'll also be able to get a good idea about the condition of the whole motor (provided you've got the right tools) - and with these things information is power - make a decision based on that.
Keep in mind, if you buy a second hand engine, you'll be buying someone elses problems, and quite possibly the same thing will happen again. Unless you are 100% sure you've got a good motor its not really worth it long term - you're better off rebuilding what you have at least you know it is sound.
Just my experiences
PS was that Mark from QLDs old car?
