Having issues with engine timing. I can tell the timing is off. Computer is telling me it’s cyclinder two and bank 1 sensor 1. Changed my fuel injectors and spark plugs. Taking out cyclinder twos spark plug I noticed lots of burnt oil on it so i got underneath and took some pictures of oil leaking from my exhaust. Which is probably why my bank 1 sensor 1 is giving a code. I’m not sure what to do at this point. Any info would be greatly appreciated.

This is where my exhaust connects to my engine right above my bank 1 sensor 1 O2 sensor

Same as the other photo just a different angle
