theres probably a reason he goes through so many engines. same reason why it's so cheap

 

and if the engine was stolen... and you bought it with out running the serial number.... can you get in trouble too??? isnt it possesion 9/10th of the law???

 

if the police happened to run some serail numbers on the parts in your car and the engine came up stolen, you will bear the brunt of the charge as you are in possesion and you have no proof of who did take it. you'd be up some sort of creek and be without essential tools in that situation man.
