Wtf Is That Noise?!

[engo]

hey guys..... there is this dam noise that has only started about a day or so ago... i was driving home at night... and noticed that the car when it hits full boost (1 bar) a wistling, screeching kind of noise is comin from the turbo area... it is most noticable when u boot it in 2nd...and gets less and less as the gears go by... i checked for leaks and so forth.... and had a look in the front of the turbine to see if the props are all tight and everything seems fine... its a really weird noise... and i am sure its either the turbo or the external gate.... but stumped/... its a r33 with a t04e garret turbo high mounted..with all the bolt on mods.... any help would be appreciated... but this sound has me sketching!!!!!... thanks guys

gaskets?

between engine and manifold

manifold and turbo

turbo and dum pipe.

see if all the bolts to those are tight (or even still there)

anyone with n e ideas what so ever.... ??... all bolts are tight...external astegate is tightened up and all... the only thing that looks wrong is an oil leak from the side of the engine (its tiny tiny tiny) and i dont think that would have n e thin to do weith it.... cause its been there for alot longer than the noise...

thats initialy the next step....but hey... DIY dont go a stray...thanx for the help

sounds like its an air leak. could be gaskets. Also try checking all the silicon hose joiners are tight. u say the exhaust gasket has been recently replaced, the mechanic could have been lazy and not tightened everything up

honestly. it could be any number of things. u could spend the weekend tinkering around and still not fix it...

take it to a mechanic.

mine was the turbo bearings destroying themselves. high pitched whistle on boost that got worse and worse.
