Think My Turbo Is Dying

[southern_tango]

Yesterday after work ,my car made a metallic noise ,and boost didn't go over cero after driving a bit more noise went away and boost was back,so I though that was it just a mere boost drop.

But this morning it happened again,noise ,no boost but no smoke or anything else and after 2 minutes all normal...but when i put my ear next to the pod i still can hear a metallic hsssss.so the louder noise looks to happen when car is cold

Now,that this mean my turbo is going to die?what could I espect to happen?

(I was thinking to do the 100000 Ks. service myself but now...)

My car is a 1999 S2 Stagea RS4V usually I run 10 psi of boost now I put it down to 7psi.(BTW miss wants to kill me for play with the boost) and I just put Motul 4100 (I know CHeap ass of me)around 1000 Ks ago...

Hey buddy....Kinda sounds like the turbos being starved of oil...if its comming and going....Just an Idea

yes,that's what is happening...

So this started happening after the oil change? what weight did you use?

Drop the oil and put some decent stuff in there..

[southern_tango]

Not really after the oil change ,I did it about a month ago or a bit more(Old stuff was black and Thick) and replaced it with Motul turbolight 4100 10W40 and RYCO Z442 oil filter...

Now it happens when the car is cold ,if I accelerate a couple of times it goes away but still there a bit...

Checked my oil and it's a bit black not as golden as when i put it...Is that bad or common?(Changed oil in my cars before but never checked the color after...)

If its not boosting it could be the wastegate but it should still boost up high in the revs. Im thinking its the bearings are shagged. Have you tried tightening all the manifold nuts?

The best fix may just be a garrett one.

The oil's job is to suspend all of the contaminants in your engine, this is why oil goes black. If it doesn't go black it isn't working.

usually a signal that the bearings in the turbo are cactus. the shaft has excessive play or float allowing the blades of the impeller to rub against the housing. only way to confirm this will be to pull the intake off the front of the turbo and give it a little wiggle (obviously with the car off!). a tiny bit of movement is normal, but anything significant is a problem.

Start reading here... linky

the whole page wouldnt hurt

Check oil level, check gaskets, check for vaccum leaks, check oil lines to the turbo.

Go to a mechanic.

Today I took the intake pipping to check if there was any play in the turbo's shaft and found nearly no play just a 1/2 mm. back and for but nothing sideways...

So,no smoke ,no oil leak *to the ouside of the turbo and no play just teh bloody metallic noice ...

*found some oil inside the pipping that goes to the SMIC and the pipping going to the throttle ,is that normal?

Yeh normal mate. Drop around if you like and I can have a listen.

Thanks,Scott,but the bloody thing omly happens when it's cold ...after a while sounds normal

Perhaps the turbine is rubbing until the housing expands with heat. It might be a simple as re centering the exhaust side, gives you a chance to check out the bearings while you're there...

Think you may be right in this one,thinking about it when i put the dump pipe , forced a bit to make it fit ...guess now it could had damage something with the time...need to go to a mechanic ...but i'm lazy ,with little time and money
