Good evening all,
The rover (2.5 DT) has developed a whistle when accelerating hard. It stps when I lift the hoof off a bit. I read from searching on here that it could possibly be a leak in a turbo hose? Hoping its just a leak and not the turbo on the way out.

Had a look but can't see anything obvious. Should I be looking esp. on the high pressure side? any particular place prone to going? It still runs fine, fuel consumption just the same etc. Help appreciated thanks

a worn uj can have a whistle/cherping sound aswell.

You would loose performance if it was a turbo/intercooler hose. Get someone to give it a rev, run your hand around the pipes and you should feel it you have a leak. Have you checked your belt tensions lately, serpentine and A/C ?

Thanks Alan,
nope, I haven't! Should I? I assumed (obviously wrongly) that there were tensioners on these. :doh: Which one could cause a whistle?

The A/C tension is adjustable, the serpentine belt has a preset tensioner but if the belt is old and stretched it will whistle/scream under load and stop if you lift off the revs. A/C tension setting is described on Rave.

Ok thanks. I'll read up on it just now and have a look. Tomorrow will do tho', feelin a bit old and stretched myself tonight.

Know the feeling, we are all just guessing at the probable cause so don't dismiss a dry u/j joint as Wil posted.

I just lost a similar whine after re-fastening the starter motor. It was just hanging on by the last bolt, and I guess the whine was air being forced out the gap by the flywheel.

Nothing worse than having air forced out of your gap.
