Is the photo showing where that hose meets the turbo? I can’t make it out but see some heat shield so assume back of the engine near bulkhead?
Failing that, intercooler hoses as per other posters replies. I wouldn’t worry about the amount of oil and grime shown in the pics by the way.  |
As a learner and listener, who’s new to diesel (with turbo) motors, I’m so indebted and appreciative of both your response and others who have helped. Massively appreciated! I did manage to tighten the o-ring slightly, but when I drove it afterwards, there was no change to the whistling sound (but it’s definitely the location where the sound is coming from( from what I can tell). As for the other tubing (first 3 photos) it does seem to go into (or at least towards) the turbo via what looks like the egr/throttle body location. I didn’t have an alternative clip with which to try either. Many thanks again!
