Ok, blue pipe that goes back towards the bulkhead is open ended (not connected to anything) but is pushing out exhaust gasses for whatever reason
the inlet pipe comming from the left leads to....

which is just above and to the left of the oil filter and under the air inlet manifold on the front of the engine.
So any ideas what it is, what it does and why there are exhaust gasses comming out of the blue outlet pipe?
