I just bought a 2008 535i with a seized engine good price i couldn***8217;t pass it up. So im going to buy a used engine and possibly pay to have it put in depending on price . My question is what else should I replace while the engine is going ti be out ? The car has 98k miles on dash but according to carfax it has 163k the car doesnt start and u can see alot of wear on the pulley thing like they we tryna get it started. Also is there any way to check if its the engine for sure?
