And you have to retune the whole engine timing too right cause they relied on the precision of the timing chain so much. But thats mainly a problem on the later i4 based engines(including their v8 which is pretty embarrasing tho i guess nowadays a premium german car having serious problems is just usual). The m52 and m54 are made out of vibranium from my experience and they run like heaven to this day.
