All he is doing is looking for advice before pointing fingers. He is looking for opinions based on the description of the event. He didn't knock ne1 and you can't blame him for being frustrated when you spend 2k on turbos maybe another 2k on a motor and the things don't even last 2k miles. Now, if it overheated due to a problem from a rebuild, that's one thing which could have easily been corrected and i'm sure z1 would be more than willing to fix it. However, if he continued to run after the needle is shooting up to high temperatures, than it's his fault the motor blew because you should stop the car b4 it even reaches 3/4 of the way up. Either way, there is no reason to get flamed, the guy is just trying to look for advice b4 making accusations, it's not like this is a $50 problem and if everyone knew the answers to car problems then forums like these would not exist...
