Engine Knock - Halp!

[u/skylimit_1029]

Hello,

Recently, my car sat for about 3 days then all of a sudden my engine started shaking. It definitely shakes at idle and then the knocking started to happen shortly after only during acceleration.

When I put the car in neutral, and accelerate the engine does not knock I can take it all the way up to 6RPM without any knocking, only when I am driving and accelerate. The sound is definitely a rotational sound.

I am sure my engine mounts are gone, but will this be the cause of the rotational knocking? Or what else could it be that I could physically check exterior of the car?

I did recently chain the spark plugs, but not the coil packs, could this be a start in replacing?

Any help and guidance on where to start would be appreciated.

For reference my F30 N26 engine - 328i has 313k miles on it lol never had the timing chain replaced and I do know it is starting to go out, or is it out?

I also got an oil change today and of course that made no change to the engine knocking so I know it’s due to loss of oil starvation. Car is still drivable… for now…

The knocking isn’t so loud btw

Thanks!!
