So I decided to check my chain line since there was noise coming from the drive chain. The noise is only there on part of the stroke and then comes back in the same pedal position.
Here's an album of the chain line:

The chain line seems to be straight but the chain is wobbly.
I've also noticed strange wear on the chain ring. Here's an album of that: Chain ring albumr 
As you can see it is not worn the same way all around the chain ring.
Anyone knows whats up? Is the chain toast perhaps?
