My 90 200 used to leave snot deposits in the air filter inlet trunking, tried an oil catch tank all that did was collect more grey gunk, routed pipe to atmosphere (under servo) and guess what? not a drop of oil/water/snot nada over 6/7 years later.
The 200 in the series is er well worn! and when hot after a motorway run it breaths like thomas the tank engine, again breather to atmosphere (down side of block) always oil mist evidence but no oil runs, and all the intercooler pipework is bone dry inside.
To the best of my knowledge both turbos are original (93 models).

Rare to change a turbo on the trucks at work, I bet the whole workshop between them might do 3 or 4 per year, that is 150 trucks doing at least 100k each per year.

I personally have had to change one turbo on my cars in 30 years of turbo diesels, and that was due to casing cracking.
Cheers, lynall. That's cheered me right up. :)o_O
 
Well Done re the grey, we saw several of the quarry we were after last night but no safe shot on most.

We put peanut butter on the treadle in trap and bird seed that seems to draw them in..

Re the turbo will put a post in my thread...bad avo, turbo changed but....

Decided to bite the bullet this afternoon.
New oil filter and fresh oil in.
Disconnected the cyclone breather and put a wine bottle top over the end.

Took it for the same 6 mile test run.
Here's the result.

Oil splattered all over the IC pipe, but it's hard to see because it's clean oil.
Here's the card I had behind it.

You can see the curved profile of the IC pipe along the top of the oil line.
It's blowing a fair bit of oil through in a short space of time :(

I must admit I'm a bit gutted and don't know what I could possibly try next. :(:(

The Landy ticked over for a fair while on the drive before I set off, say 5 or 6 mins. The oil pressure at this point was about 3.6 bar.

When I got home, at tick over, it was a shade under 2 bar.

What do those pressures look like? I've thought they were ok. I could put a pressure regulator in to drop the pressure to the turbo to 40 psi (2.75 bar)

Other that driving it down to JM's place, is all I can think of doing next.
 
I still think you need to pull the manifolds to confirm it is the turbo passing oil and not the engine?

Can you explain what you mean a bit more, lynall. How can the engine be passing oil out through the compressor side of the turbo :confused: I'd love it if you had a solution, but I don't get it. :oops:

Ignore me, you are right, my mind is askew as usual!
 
Damn :( Thought you had something there!

I would still have to look myself just for piece of mind, and to be 100 percent that is was the turbo at fault, especially as its the third one, and they aint cheap.

What would I be looking for?
 
Anything out of place, if nothing wrong all its cost is a gasket and a couple of hours labour.
My mind would not rest until I knew what was going on!
I haven't got a clue what's going on. And my mind can't rest.

I think I mentioend this on your previous thread on the turbo issues, is there a flow restrictor controlling the amount of oil reaching the turbo?

It's standard, but I can only think my next chance is putting an inline pressure regulator in. I can't understand why my engine would need one, but I can't think of anything else I could try.

What about the banjo bolt in the top of the oil feed line, is the hole smaller than the pipes bore to restrict flow/pressure?
Is it the original banjo bolt?

Edit ignore that, just googled it ERR1125 hole looks quite a size.
 
Have you tried the oil splatter test wth no inlet trunking connected? ie turbo totally bare of all air pipework.
Same test with rocker cover oil cap removed?

If anything, I think I must have too much oil pressure? The banjo bolt is original, the HP oil feed pipe is aftermarket.
 
Some interesting images,

That is what I was getting at, ie did the original bajno have a smaller hole so reducing flow/pressure, but after googling the banjo part number that would not appear to be the case.
