I'd say it was fairly inconclusive....
The amount of oil that appeared in the IC input in the video would not be enough to cause run away, so there must have been more oil conning though from somewhere else.
Most of what you see in the video seemed to come up from the sides of the silicon pipe, which was left over.
When I first got my T2, it was using oil, and in the end it started doing what yours did. I think mine was "banking" the oil in the IC, and when I stopped at a junction, and the car was leaning to the drivers side, it ran down into the inlet manifold and ran away. Luckily, the few times it did it, it ran out almost as fast as it started, and only once, did I need to stall it.
In my case, it came down to a combination of things.
My Turbo was leaking oil. This was proved by thoroughly cleaning everything up, re-setting everything up, but removing the breather hose and blocking the hole in the pipe that runs from the airfilter to the Turbo. Make sure to stick the end of the breather hose into a container. I then ran the car for a couple of days, and re-checked the turbo and intercooler, it was full of oil.
After I changer the Turbo, things improved, but I was still using a bit of oil. This was when I discovered that the Breather Control valve was not working properly, so I fitted the catch tank.
At the same time, Rick did my valve stem seals.
These pretty much improved it all, but I found that I can only half fill the oil on the dip stick. If I take it up to the full mark, the oil still somehow ends up in the turbo, but I have never worked out how, as there is nothing in the catch tank?? As long as I leave it only half way up, the car uses hardly any oil...
I have now just accepted this, and given up questioning the nature of the Terrano:bow:bow
