oka I am noob to bmws so please be very detailed and treat me as i know nothing but I was about to trade my teg for a 94 325i bmw 6 cylinder then the guy told me that car needs exhaust cam and timing chain. I assume timing chain broke but i know in hondas if timing belt breaks valves bend but in bmw what could of or did happen
how difficult is it to change cam and timimng chain
