New BMW owner and need some advice
Hello, I am new to the forum just purchased a 2003 BMW 325i from an individual about 2 weeks ago for my wife. Car was really clean and looked to have been taken care of. Exactly a week later the expansion tank cracked. So I ordered a tank and put it on and bled the coolant system. The car was still overheating. So I took it to a local import mechanic. Mechanic says engine compression is getting into the cooling system. And that I have either a blown head gasket or cracked head or block. So I am looking at replacing the engine. I am more used to working on american hot rod type rwd vehicles, so I am kinda in the dark on a newer model BMW. How much trouble is it to swap the engines out myself? Any specialty tools necessary for swapping out the engine? Or will it be better to just pay the extra money and let him do it?
