Turbo whistling noise???

[zollaf]

well, could be the turbo on its way out, or a split boost pipe or cracked intercooler, leaking egr valve, but basically its likely to be a leak somewhere in the high pressure boost side of the inlet side of things, but could also be a leak in the exhaust manifold.

Turbo has been rebuilt and well maintained engine has bew intercooler new egr valve it oly started today to make that noice but when stationery and i rev it it doesn't do it oy wen drive but its definitely coming from engine not from wind
