well im bein dumb again, had a proper look and its a single rubber pipe that is kinda springy in the middle comin from the air intake box (where the scoop sits above on the bonnet,intercooler maybe its called,doh)at the bottom (drivers side)then to sumting near the exhaust (is that the turbo??????) you can see it easily enough at the top of the engine. sorry if this dont make sense havin trouble explaining cuz i have hardly no idea about this engine!!!! if u understand what ive said any help on why the oil is there v.v.v.v.v.very much apriciated.

I think you mean the turbo outlet to intercooler hose. Oil coming from here is not good but does happen. The oil is from the Turbo bearings and is leaking past the ring seal on the turbo shaft.
This can mean that the turbo is worn (how many miles has the car covered?). Turbos are generally very reliable when used correctly and this includes alowing sufficient 'spin-down' and cooling time before turning off the engine, regular oil changes etc..
To check to see how bad this is remove the intercooler, being carful not to damage the very delicate radiator vanes, look into the intercooler oulet (large hole!) and see if there is oil present
(there will always be a little). If you can pour the oil out you may have a problem! Simply wash all the hoses and flush the intercooler out with a suitable engine wash (or parafin). The intercooler needs to be perfectly clean inside in order to work efficiently. Replace the intercooler when dry (blow through with compressed air). If a large amount of oil was present (ie. puddles in the intercooler you may need to get the turbo reconditioned. Otherwise run car for a while and check to see if oil is present again.
Incidentally is the dump valve working? If not the compressor side of the turbo can see a big vacuum on lift-off and this can suck oil past the seal.

The main turbo oil feed is a metal banjo pipe all the way....from a tapping on the end of the RH head up to the top of the turbo....the oil gravity drain is a big rubber pipe off a stub on the bottom of the turbo straight down to the oil pan - you can barely see it.

The turbo also has water cooling - these are metal banjo to rubber and bolt onto the side of the turbo. This sounds more like the hoses you are describing......is there oil on any other pipes....sounds like the oil is misting from somewhere and covering all the pipes.
