Thread: Noisy Turbo

Definately sounds more like a classic leaking exhaust manifold gasket. Search 'Td5 exhaust studs' and you will find heaps of info.

[FONT=""][COLOR=""][SIZE=""]Definitely broken stud or warped manifold.when mine started I swore it was a belt problem until seeing how common it is.sorry to hi jack but saves creating new thread,my turbo and has for a while,a strange fffft noise like a little bit of air escaping or something,right on the start of throttle then stops as you apply.I know that's really bad descriptions,but it's hard to describe![/SIZE][/COLOR][/FONT]

Guys- how did we go with this? I've an '04 TD5 D2 188K and I've a whistle at low speed acceleration (under load).
Sounds similar.............

Had the same noise...turned out to be the exhaust manifold

A higher pitched whistle is more than likely a leak somewhere such as exhaust manifold. A more pronounced whine will indicate wear in a turbo. Or best bet, take air intake off and have a look at the impeller. If it has any sideways movement then it is likely rooted.

Thanks Guys- that's next weekend fixed!!!

I've found that a very high pitch whistle/shriek at high revs 3000+ is a blown intercooler hose, so that's something else to check. I had exhaust stud, one hose and then the other, go in quick succesion, a matter of weeks.

I had the same noise about five months ago. Turned out to be exactly as described above. Two trips to the workshop (replaced exhaust manifold gasket and studs, second trip to fix the fact that they didn't re-assemble correctly and oil was going everywhere...) and a hefty labour bill later , fixed. Or so I thought. Driving up from Canberra to Sydney today.... Same noise. Less than six months and 10,000 km later. Could this be right or a stuff up somehow by the workshop? I am trying to work out how first one lasts a decade and 150,000km , next one less than 6 months and 10k?
Any thoughts?
Thanks.
