Hey guys. After a second opinion. I got a second hand motor for a 96 Wrx sedan. First engine blew bottom end bearing. Got second motor installed with a 1 month warranty. After 1 week engine failed and has done the same thing. After taking the car back he pulled the computer out and said it was a 'zero' brand rally computer and was running advanced timing or something like that. He now won't warranty the motor. Is this reasonable or am I just getting shafted? I'm not a mechanic or experienced with these engines so any advice or help is appreciated. Cheers
