N20 Timing Chain - Good or Bad??

Hello, I have a 2013 328i XDrive with 150,000 miles and the infamous N20 engine. I got 2 low oil pressure lights with no symptoms and all have disappeared since (the errors only came on while driving 80mph and no permanent codes). I then checked the timing chain and it appears to be loose (both the guide/tensioner and chain) when the engine is cold after i let it sit over night. I then started the car and revved it a few times (still no symptoms or odd sounds). I checked the timing chain and guides again and it was solid as a rock, did not move even a centimeter. Is this the beginning of the end for the motor or is this fine / normal? Thanks all
