BMW N63 engine noise
 

A knocking strange noise was coming out from my BMW N63 engine. Then came the surprise, a noise from ... cylinder N1 conrod.
A real disaster and shock for me.

That shouldn't have been a surprise as that's what the N63 is known for. A lot of people buy them not knowing the history behind the N63 and I say they put themselves in the situation because you're supposed to research before you spend your hard earned money on a big purchase. Heck any purchase. If you did do the research then you should of been prepared for it because it's never if it's going to happen but when it's going to happen when it comes down to the N63
