Hi folks, learner mechanic here again.
OK, so yesterday my Bongo started making a light whizzing sound when under acceleration
Before I start tinkering about, any ideas

folks
Whiz only happens when accelerating with medium-heavy pressure on accelerator pedal....no whiz if being very gentle??
thanks in advance

Check the number 1 stud on your exhaust manifold gasket, under the passenger seat. Not usually described as a qhiz, more of a squealing pig......

Thx Ian, will check, but more of a large mosquito than a squealing pig

OK, so I discovered & solved the problem...
The EGR pipe connection at the front

A close inspection revealed that that it was only connected with one bolt

and that one and only bolt was loose/threaded and not holding the connection tight
Anyway, fitted a blanking plate (c/o Allans Vehicle Services), A new bolt & all is quiet again
...........................
Go to find a 2nd bolt or hope the one will hold
