You check all the intake pipes and removed them from the Turbo ?
Could possibly be turbo oil seals gone ?
Just be careful as Diesel engines will run on there own oil if the turbo passes enough

Re: excessive oil on breather 1.9jtd sporting

yeah checked them all there bone dry since i removed the crank breather from the intake pipe ... just worried as the oil catch tank fills up quick ... i had a astra gsi that was bad for leaking but never had crank issues or never owned a diesal before haha ... turbo seal seems fine and hits about 25 psi in 6th gear at 3 thoe revs and holds boost fine

Try dropping the oil level to half way between min and max.

That's a HUGE difference.

Sounds like worn piston rings.

Re: excessive oil on breather 1.9jtd sporting

If the intake is bone dry, it's not the turbo, thats fine. No need to worry there.

The fact your catch tank is getting half full could be one of 2 things.

1. You have excessive blow-by. It normally carries oil vapour through the breather pipe anyway, but excessive carries more, hence filling up rather quick. This could be a sign of worn piston rings, however, could be seen as normal in turbo'd engines. Not sure on the figures you should be looking for on a compression test on a diesel, but once known, you should be able to diagnose from there.

2. Oil being flung and splashed around from the valvetrain could be being carried through the breather with the blow-by gasses, causing it to fill quick.

Seeing a coating of oil in the intake is normal, unless it's excessive, which does warrant further investigation.
