I blew my engine??
hey everyone so yesterday i was driving to work on the 405 in socal and it was 95-100 degrees outside, and my ac was BLASTING, right when i exited the freeway and i was behind the light right when i got to the light i put my foot on the gas when it turned green and realized my cars off... so i didnt think much of it, then i cranked the motor to see if itll start back up... it didnt so i worried then i looked and saw theres alot of smoke coming out of my engine, i pushed my car to the nearest gas station and apparently i had a leak in my radiator so i filled it up with water and the water started gushing out from inside and there was more smoke, later on i got my car to turn on and there was this weird sound like a (tak tak tak tak tak tak) sound coming from my engine while it was on, so everyones telling me im going to have to do an engine swap or a full head rebuild and im looking at around 3000-3500$ to get this fixed...
my car is a
2000 323i i only have 110k miles on it
so what should i do? what would be the best move?
