Advice please

1.6 td jx

I have a blowing air type of sound coming from around the turbo only when at top end of revs under load.Its not there when parked up and revved up.it seems to pulse at at very top of revs.
It drives and pulls fine until top end of revs.
So I decided to check turbo and hoses and found a small amount of oil at bottom of turbo.I then took all air hoses of as there was some oil splattered on air intake hose and found lots of oil in all hoses.
Excuse me as I am trying to learn about fixing things myself with little knowledge
The turbo shaft has no movement on it but has a very small amount of oil splatter in pics

Here is some picks of hoses and turbo

Your photos make it look like the turbo drain is a long way from 6 o'clock position. Turbos rely on gravity to drain the oil and also they dont have oil seals as such so any restriction on the drain will push oil into the inlet or exhaust or both.

mgm can you point out the turbo drain please

The pipe that goes from the middle part of the turbo to the bottom of the engine. It should exit the turbo within 15 degrees of vertical. The standard jx drain is a mix of solid pipe and braided hose.

Ok got you oil return.thats the way it has always been since I got it 8years ago.so what would make it change ?

It wont change on its own however if the turbo was swapped before your ownership it may not have been installed correctly.

Could this be caused by to much oil as last year I bought a new dipstick as my old one had no plastic feed tube ?
Just wondering if it might be a couple mm out

Before you start pulling things apart..
how much oil is it using?
Its possible that the blowoff valve is opening [at the top of the rev range]
Your on the start of a new learning curve!

Too much oil cause the turbo to leak like that.
The only way to tell would be to drain the oil out, refill with exactly 4 litres and check the level before starting.

dave I have already started pulling some bits of that I think I can manage?I have taken all the hoses of that were caked in sludgy oil.And had a feel of propeller shaft for play.i have researched quite a bit of other threads to see what it may be.
It has always used quite a bit of oil on a long motorway journey to france 3000 miles 2 to 3 Ltr
Around the doors I seems ok.
I cleaned all hoses last week inside and out and went for a trip out and noticed oil splatter on air intake hose from the blowoff valve.
Would it cause a blowing sound at high revs dave. ??

Blow off valve..shove a wine cork in it!
And as MGP check your oil..oil use looks ok.

Going to take it to local old school vw garage tomorrow for him to have a look.
I will let you know what he finds ??
