Hello. I've noticed that I have oil pooling on top of my rocker cover. It seems to originate from the pipe connection behind the coil pack for cylinder 1 (marked in blue) but I have also noticed that the breather connection for my PCV valve (marked in red) is covered in oil as well. Furthermore this morning I had a misfire and codes P2301 and P0301 indicating a misfire from cylinder 1. I swapped coil packs 1 and 2 over, cleared the codes and went for a test drive and the fault didn't show up again in either cylinder 1 or cylinder 2. The pipe marked in blue appears to go to the oil cooler at the front of the block and then down towards the turbo but I can't find a schematic showing this pipe. Has anyone experienced similar? I'n guessing I need to change the PCV valve but I'm also assuming that once an oil seal has been compromised it will need to be changed as well?
