Well i dont know what you mean by both ends ..as one end is buried in the manifold,...and gets driven by the exhaust gasses, the other end is the intake makes the boost
The pipe leading from it going strait up is still on the intake end this has a breather pipe going to it
You can only see 1 end of the turbo...and that's the one the air cleaner tube goes to
The oil feed and oil return would need to be looked at
If the oil is coming out of the impeller.....the fan thing ..without engine breather pipe attached ..then yes turbo has failed
Well ive never seen a turbo tested like this .....you also got to factor in that the pressure it makes when sealed up .... may stop the oil coming out in quantity until its really failed...
You could be talking about oil coming out of the boost tubes ...it does pile up in these in certain places ..just before the inter-cooler is a drip point . where if you haven't got a good seal,. it drips directly onto the brake vacuum unit. this oil is usually from the breather system.
The boost pipes and intercooler accumulate the oil ........which has to be cleaned out every service by dismantling everything, the older and more worn it gets the more oil ..i suppose.
I don't know if this oil clears itself out if you thrash the thing ....as i only trundle round in mine. never doing over 2500 revs, especially since the 20mph speed limit here in wales
all the best.mark
