pd150 engine leaking oil from turbo! help!

[cra1gy1989]

Hi, right now I am lay under my car, oil dripping on my forehead, from what looks like the centre/ inbetween the two housings where the turbines sit... oil looks like it is coming from the exhaust side of the turbo but not the side where the exhaust bolts too, on the opposite side of the turbine, I only replaced the turbo 3 months ago... I don't know what all the parts on a turbo are called so if anyone could help me.I would be appreciated..
Thanks

In the centre of the turbo between the inlet and exhaust housings will be the high pressure oil line for the bearing lubrication, it could well just need tightening. The banjo bolt should have a pair of copper washers and ideally these should be renewed when fitting a new turbo, if they werent this could also be the problem, a a very cheap and easy fix.
Hope this is some help to you.

Pretty sure it will be the turbo oil drain. The metal gaskets are not very good, I ended up making my own with gasket material. If you end up using some sealant be very careful not to use too much and block the pipe.

Lol, it's either of these :-)

Thanks a lot, is it a turbo off job? Or maybe a awkward on job, just a pain to get to as its at the back at the. Bottom! Cheers

I have tried tightening the oil pipe and it is peaking from higher than that, there looks like a metal gasket of some sort on the back side of the exhaust turbine not the oil feed pipe I think you are referring too... cheers

It can get blown around whilst driving. Have you got a torch and a mirror on a stick? Higher up? Are you sure it's the turbo?

As Steve mentions, are you sure its the turbo? Above the line of the turbo housing is the head gasket(highly unlikely though) and the cam cover gasket (much more likely). All the oil needs to be cleaned off, preferably on a ramp with something like brake and clutch cleaner and the car started to then watch exactly where the oil is coming from. It is indeed in an awkward spot and with the engine slanted rearwards does make it difficult to see the rear of the block without a ramp. If oil was leaking between the housings this would suggest the main bearing oil seal in the turbo housing had gone which would lead to major exhaust smoke and possible runaway engine. I would tend to be looking for that leak elsewhere before condemning the turbo.

Thankyou very much, as I only replaced the turbo 3 months ago, I have found my old one to try and figure out where it is coming from....
after having a close look at the old turbo, is it the turbo actuator? There is a bolt that you can adjust which chooses where the actuator sits, there is oil leaking over the top of that, above the actuator lever, there is the other side of the main bearing oil feed, which I cannot access from the top without removing intake manifold... but could it be leaking from there?

Is seems to be running straight down the centre of the turbo and dripping off the bracket that holds the actuator in place... really really awquard to get a good view of where this bleedin leak is coming from! And I don't want engine runaway! Or in this case have to buy a new turbo as the seals have gone!!!
Thanks in advance..
