This model has no oil seperator, only a circular shaped PCV valve externally. IMO, later 1999/2000 MY EGR versions have the pcv/seperator built in the cam cover.
As you say there could be some valve to hold oil after engine shut down to cool the turbo.
will check carefully.

Removed the oil return line completely. There us no control valve or anything but it just drops to sump. Howver,about 1.5 ltrs of oil dropped from that opening. Even the minimum oil level(as per dipstick) is above this point. That's why return line hose (about 3 inches) was full of oil prior to removal.
As Wammers said, I think the PCV side is playing up hence high internal pressure in the crank case not allowing the turbo oil to drain. Will remove the PCV full & reinstall the turbo and see how it's going to be.

The cam cover with the internal PCV came in with EGR in 1998. Have you looked inside your cam cover for the mesh separator?

Mine is 1997 MY, no EGR. So, PCV valve located side cam cover.

I don't think you are listening, i know where the PCV is. But that is NOT the main oil separator is it. I am not 100% certain but there maybe a large gauze separator inside the cam cover.

Got waht you mean.
Cam cover has a set of plates reveted/ brazed together but nothing serviceable there. It not possible even to see the PCV connection.

Btw, the form of the sump is such that at least 1 inch of oil there above the sump gsaket level when full. So, wondering how the free flow of turbo return oil is maintained, as it connects just above the sump gasket.

Are you sure the plate is not removable to expose the gauze separator. Later ones had eight or nine screws holing it in place. If you can't get to it, soak the cover in solvent to clean it out. Don't know can't find any info on Turbo drain, but looks like it goes in above internal splash guard and not directly into sump. Maybe it secondary feeds something else. Will keep looking.
 
Checkded dipstick n tube they are okay.
going to clean the PCV valve n refit the turbo.
can do it in the weekend.
TRy first without the catch can setup to see how it goes. Think that i need to clean the intercooler too.

Cleaning the intercooler is a must should be done every 48,000 miles. I doubt the dipstick was ever a problem. Have you cleaned out the cam cover?
 
I cleaned the IC about 4000Km ago. Do I need to do it again, after this event?
Will clean the cam cover this week end with all the other work in the car.

If the manifold was swimming with oil you can bet the intercooler will also be full of oil. You maybe better to try and get hold of the later cam cover with the internal PCV, a couple on eBay for not a lot of money. The external one never was much good and costs a bloody fortune to replace.
 
Got the turbo installed without input & output hoses.
No catch can or PCV valve.
Started fine idled for 5 minutes or so.
Raised RPM to 1500 within seconds see the turbo output in the photo.
It was very clean & now it's with some oil seeping from inside.

As noted before, I'm sure no unusual movement on the impeller shaft.
Also, can't be the oil drain as when the engine runs level in sump drops due to circulation by the pump.

Any views appreciated.

Oil level in sump will always drop when engine is started, that is why when checking oil level cold you start engine, wait until oil lamp goes out. STOP ENGINE, then dip and top up. Why don't you stop buggering about and fit a new turbo i would also recommend you fit the later cam cover with the internal PCV.


Edited for reasons of clarity.

That goes against everything I have ever read about checking oil levels. The P38 owners manual states check level with engine cold, no need to top up if the oil is nearer the upper mark than the lower mark, other manuals state check with engine cold or allow time for oil to drain down before topping up and that over filling is dangerous.

Standard practice when changing oil is top up until high mark on dip stick. Start engine, when oil lamp goes out stop engine. Dip and top up to high mark on dip stick. Prevents stroppy know it all customers from complaining you have short changed them on oil.

You forgot to mention stop engine in your original post:rolleyes:
 
Okay. Will get the turbo repaired. I can,t afford to buy a turbo now.
Will include newer type cam cover in the wish list.

Thanks for all views/comments n advise.
