So, I finally got around to taking the airbox out. Seems like the oil leak is at the pressure switch as I assumed.
What would be the best tool to get the switch out? I gather that there is no point in trying to tighten it.
I have read that you can't get a deep socket in there(i would have to buy one to find out). Advice is to cut some of the switch off so that a normal 24mm socket will fit.

Any better suggestions? I could try vise grips. Not sure how much torque is required to fasten it though.
