Having just replaced the turbo on my car, 52 reg Sti, It now seems that I have no oil at the pipe going to the top of the turbo, when I fitted the new Turbo (2nd hand of broken scoob) I bled the system (oil flowing from the bleed screw) today in using the car I had a very load squealing from the engine, which i traced back to the turbo, in turning the engine off I could here the turbo slowing down with now a clicking noise, in loosening the oil bleed screw there was no oil coming from this screw (engine running).
two questions, am I right in thinking that the oil pipe maybe blocked if so how do I clear it, and second question, is this turbo now knackered.

i believe if you trace the pipe back to the banjo bolt on the block pretty sure there is a filter i think inside the bolt of the head that you can simply pull out very unlikely but check this is not blocked,sure this pipe also feeds the AVCS heads/solenoids .

also worth a check as you have changed the turbo check you have not bent the metal pipe any where when you moved the oil feed out of the way

 

When I got a new turbo for my STi I was advised to bin this little filter as it can easily get clogged and wreck the turbo.

 

Indeed.
Forced Performance actually recommends binning the filter, and other Turbo manufacturers do this as well.

A common fault is if the little filter has fell out at some point, during disassembly or reassembly it gets put back the right way round, if its wrong = no oil flow.

 

many thanks for all responses, will stick head under bonnet today.

FILTERS COULD HAVE BEEN CHOAKED BUT IF ITS CLICKING TOO, IT SOUNDS LIKE NO OILS BEEN GOIN ANYWHERE AND THE OIL PUMPS POSSIBLY BEEN THE CAUSE .

(MOTOR S GT - YOU'VE GOT YOUR COMMON PROBLEMS CONFUSED MATE. BEST REMOVING THEM, BUT FITTING THEM THE "WRONG" WAY THEY SHOULD BE IN THE BANJO BOLT WOULDN'T STOP OIL FLOW UNLESS THEY WERE CHOAKED UP ANYWAY.

IF YOUR VERY LUCKY, THE NEW TURBO IS F@CKED MATE. IF YOUR UNLUCKY, THE WHOLE ENGINES F@CKED.

 

As I read it the turbo is clicking, not the engine.
Do you have a oil pressure gauge??

I believe the oil pressure warning light comes on below 0,5 of a bar, that is not much, but you should have oil coming out of that hole.So as long as the light is not one chances are the filter is just clogged or something.

 

if theres a clicking and squealing noises coming from inside the turbo theres contact friction due to oil starvation no? If theres contact friction theres abrasion. If theres abrasion theres material removed from the contact surfaces. Where does the wee bits of metal go? Think ye'll find the engine very well could be f@cked as I said. With Caps Lock.

 

All, as mentioned, still to stick head under bonnet, there has been now oil pressure light on, and no check engine light, so at the moment thinking maybe filter, with the clicking noise it was from the turbo, so I am presuming as mentioned oil starvation, hoping that that's all the problem is.

now had the chance to sick head under bonnet and have managed to find the filter in the banjo bolt and removed (was dirty), however thinking ahead, I put some oil into the bolt hole where the oil feed attaches to, over a mug of oil went in and disappeared into the turbo, is this correct ??.

Andy

 

Oil feed pipes can get carbon build up inside them and when you take the pipes off it can cause the build up of carbon to break up then it ends up in the turbo.You might want to think of getting some new pipes.If the turbo has been starved off oil check for play excess free play or if it has sized now.You are wright to put some oil in the feed pipe when re fitting a turbo.

 

it would have drained out the turbo to head pipe and back into the engine

 

When I put the oil in it went directly into the turbo as I had moved the pipe away, so not back down the pipe, going to remove turbo again and check to see where oil has gone

 

The turbo has a feed and a drain

Oil goes in the feed and out the drain and back into the head.

You could fill the engine through the turbo oil feed if you want, it means nothing.

 

Thought as only one oil pipe going to turbo, that was it, is that right ?

 

There's the metal feed pipe to the top and a rubber drain pipe directly underneath the turbo.

Now you've removed the filter, can you get a flow of oil through the metal pipe?

 

No

 

Have now got turbo off, (two hours), and it's knackered, the filter was blocked and seems to be the cause of the problem, so advice to others BIN the filter, third turbo in two months, bugger.

 

Now had a look at the outlet side and there is a gummy oily deposit, with very fine Ali in the paste, it appears that the the bearings have gone and the filings are from the turbo fins, would this cause damage to the cylinders in anyway.

 

Hi, When fitting new one (aw) Turn engine over (without firing) get oil out of final pipe to turbo, fill turbo with oil (prime), turn engine again until you get a exit flow from turbo then connect drain. You should be safe to fire up then, reassured that there was oil there, getting there and draining (complete flow and drain). Did this to my Renault 5 turbo back in 1994 and and my 1995 British spec Impreza turbo 2002 and had no problems.
