Help bp5 Turbo issue

[Rhy]

hi guys

my bp5 auto 2003 has lost ALL boost and has a strange sound coming from the area. the sound is kind of a knock ( sorry for the bad description ) only when boost should be starting to kick in. the person driving it at the time said it started off sounding like air hissing out ( like when you pull the valve out of a tire) i cant see any lines that come loose. but i have not been able to get the time to get in there and look properly. i did notice on a very quick inspection that there is oil around the waste gate, inter cooler area.

my oil levels look fine and cant find any obvious leaks in that area with a quick look.

any help or ideas, guys would be great

cheers

CEL? Blowing any smoke? Is it Idling/running fine other than the obvious?

[Rhy]

running fine as far i can tell. as far as the smoke, i must admit i have not check yet.

Is the check engine light on?

[Rhy]

no lights on the dash, but i will plug a scan tool in to it and have a look at the live stream data and make sure all is well any way

Split plastic turbo outlet pipe. i.e:- between turbo and intercooler.( where you have noticed the oil)

No CEL for this one!
