I STILL have an oil leak AAARRGHHH!!
Discussion
Car in question is a VW Bora 1.9Tdi ST PD130 and...
It's been leaking oil!! The original suspect was the Rocker Cover, so I replaced the Gasket, used sealant and it seemned to have done the trick. However, there is still oil leaking from somewhere!! GRR!! It's leaking and dripping onto the exhaust manifold, causing plumes of white smoke to come from the bonnet! There is also a considerable amount of oil on the floor when left for periods of time (overnight). I have checked the sump and cannot see any cracks. My only thought was that it could be coming from the Inlet Manifold? I have an EGR Delete but no Oil Catch Tank and have not cleaned my intercooler. Could the oil vapour in my intake system be seaping out of the inlet?
It's literally driving me insane! I can't have the blowers on because the fumes are that bad, it gets blown into the cab resulting in me also passing out from fume inhallation! When stopping at traffic lights or junctions, the smoke is piling out of the engine bay causing a few looks!
I can see where the oil is being burnt on the exhaust manifold, but can't see (due to poor access) where it is coming from!
Anyone else suffered this, or can point me in the right direction? I have posted on many VAG forums, but not as much traffic as PH...
Cheers guys!

Is sealant recommended to be used with the rocker cover gasket....It's been leaking oil!! The original suspect was the Rocker Cover, so I replaced the Gasket, used sealant and it seemned to have done the trick.
I ask because rubber gaskets are frequently not assembled with any sealant and use of sealant can result in gaskets sliding/moving around during assembly and as a result not sealing properly
I'd be surprised if a leak in the sump area could leak onto an exhaust manifold
Turbo oil lines all tight and hoses leak free?

Give the whole engine bay a good coat of gunk, from the top and the bottom, take it to the jetwash with the engine running and blast the lot down. Drive home. Lie under car with engine running and you should be able to see where the leak is coming from, soooo much easier to trace when everything is clean.
Good luck.
Thanks for the quick reply! Good luck.
I have already done this, the problem being once underneath, I can't trace the leak back to the source!
I know it must be coming from above the exhaust manifold, as it's leaking onto it! Just can't pinpoint the exactl location! So frustrating!

I can't really gey access to the turbo oil feeds due to there being precisely a gnats bollok between the turbo and the bulkhead.
ETA - I excluded this as a suspect due to that fact that the oil feed pips are below the exhaust manifold and the oil is leaking onto that...

Is it a plastic or alloy rocker cover - manufacturers have been going over to plastic recently and they can warp and no ammount of gasket replacement or black goo will stop oil leaks from a warped rocker cover IMHO
Turbo seals gone? Take the turbo off and have a look? Not sure if you'll be able to spot it if it's only slight damage. Alternatively, if the rocker cover gasket isn't meant to have sealant on, and you've checked into this on the right VAG sites, then I would personally re-fit it without said sealant and see if that solves the issue?

A cross section of the gasket looks like an inverted T, of which the leg of the T fits into a groove in the rocer coverm then the flat of the T is seals against the head.
My next thought was a warped rocker cover - but have been exhausting all other possibilities before I let VW rape me for £130 for a new one!!

my first thought, there is a orange pipe which joins to a metal pipe leading into the turbo which is notorious for leaking small amounts and gradually working it's way lose. I think the standard VW clip isn't really up to the job so a lot of people have replaced the clip with a jubilee instead. As it's near the top of the engine it is easily confused with a leaky rocker cover as oil end up all down the back of the engine....Look at this : http://uk-mkivs.net/forums/p/87676/619294.aspx#619...

so it couldn't be the turbo (granted it could be both)Just an update:
Driving home from work yesterday and the bloody Oil light came on!!
So, it's been 2 weeks since the service and has required 3 litres of oil so far!! Insane!!
I think it might be a trip to VW to purchase a new rocker cover and gasket... hopefully that will do the trick!
Also going to get an oil catch tank and clean out my intercooler so the induction system is entirely oil free!!

Further update:
Got the car in the air yesterday and it might well be that the rocker cover isn't to blame after all!!
It seems to be coming from the turbo oil feed! I have spoken to my mechanic who suggested to tighten the 17mm flare nut and see if that helps, if not, then a new oil feed pipe should do the trick!
So I will try and tighten the bolt, if not, I will be purchasing a HEL braded hose replacement rather that a rigid pipe!
If I do come to replace this pipe, should I fill the pipe with oil before attaching and starting engine? Kinda worries me to crank the engine when the turbo is going to be, albeit momentarily, without oil!
Cheers!

The Oil Pumps on all car engines are very powerful. In an otherwise healthy engine, Oil will reach that turbocharger within two seconds after start up ~ probably quicker than that. Well, it does do on my Rover and MG Petrol turbos as I've tested same. Most cars use similar Oil Pump arrangements. Observe how quickly the Low Oil Pressure warning light goes out soon after start up.
Badly worn Turbochargers on Diesel engines have been know to "run on" on their own sump oil after switching off.
