Eagle eyed viewers may have noticed the oil leak when I replaced my spark plugs and ignition coils a few episodes ago. This is because the rubber o-rings that seal the coil tubes fail over time and allow oil to pass through.
Here's my step by step video guide to removing the tubes and replacing the seals:
