Whining MINI engine (pipe contracts - why?) - pics

[MikeyT]

Got a constant whining from the engine - know what the problem is - the pipe you see in the pics below - when the engine is running it is squeezed and the whining starts - when the engine is off it returns to its original state (second pic.

Is this pipe just a breather for the top of the engine? What causes the change in pressure so that it collapses and other than install a metal pipe, what can I do?

Any help appreciated.

Hi Guys
My First Post !
Just read this post so here goes!
We have just had this problem and the pics posted on here are superb regarding this fault.
Our whining was at 2,000 rpm which drove us mad for 2 weeks !
Solution is simple !

Just take the pipe off and swap it around ! Seriously it solved the problem wihtin 30 seconds!
It will save you the time spent driving to dealer and any costs.
Hope this helps on my first post guys / ladies ?

Hi jcwuk - welcome to PH ... where've yer been?

We had it sorted at a dealer a couple of weeks ago - so all sorted now, should have tried the remedy maybe but the wife was nagging to just get it done.
