Re: oil in hose intercooleer to throttle body 940 turbo
You will have a mix of oil and water in your inter cooler,remove and clean it. remove the two hoses on each side of your inter cooler. now remove the two bolts on two bars holding both your radiator and your inter cooler .now push the radiator forward you at the front of the car.and lift out the inter cooler.now turn up upside down ,and the oil and water mix will pour out. to clean it fill with a hot water and degrees-er mix. and clean your hoses. and refit.

Leaking of any fluid is not normal. The only time any fluid should expel from the car is if you have overfilled something. Your turbo could need replacing, you could have a hole in the intercooler. Have you noticed any lack of performance or extra smoke...
There can be several reasons for this. You can have worn valve stem seals on the valves, which may change with warm oil, or you have worn oil rings in the cylinders.
A compression test when the engine is cold would reveal if the piston rings are worn. Another possibility could be a bad head gasket which leaks oil when cold and then seals when the heads warm. A compression test would also diagnose this.
if ur not changing ur turbo DONT TUCH THE WASTE GATE OR ITS HOSES!!!!! that part is only to reroute the xsaust gazzes to slow the turbo when the throttle is closed, as for the BOV or blow off valve mount it somewhere on ur pipeing that goes to your INTAKE of the motor it is there so when ur throttle snaps closed when u come off the gas pedel to shift, the pressurized air from the turbo can go out and away from the throttle usaly after the intercooler and before the throlltle body if u got the room for it also depending on the install and turbo setup, and computer, the car might tend to stall (MABY!) Depending on what kind of air metering you car uses, will dictate which is the best form of BOV, whether recurculated, or vented.
As for placement, the best place is usually as close to the throttle body as possible, that way as soon as the throttle plate closes air is evacuated...but having said that if you are recirulating, its a bit more plumbing to get that to work right...but anywhere AFTER the intercooler is good... and for the vacume hose any free vacume nipple on the intake manafold u might find one with a rubber cap or somthing of a blocker, if no nipple is availble buya Y type fitting at an auto store to doubble a used one HOPE THIS HELPS
The IC will have some blowby oil in it, but if you are referring to the small radiator looking thing on the passenger side that has two oil lines running to it, you are actually talking about your oil cooler. The IC is rather large by comparison and sits directly behind the bumper and directly in front of the radiator and it runs the full side to side length of the radiator. It has a large inlet hose from the turbo and a large exit hose to the turbo delivery pipe that runs to the throttle body. If you have a leak in the IC, you will notice decreased boost at WOT. If it is actually the oil cooler, keep a close eye on it. These do fail given enough time, and a small leak will become a large one, usually at the worst possible moment. Ultimately, you will have to replace it. The stock unit is costly. Some people use an aftermarket and relocate to in front of the radiator and above the IC. Flex-a-lite makes several that will fit this location. Remember, if you go this route, you will need longer hoses.
take off pipe going to the intercooler from the turbo see if oil is found and clean then other pipe from incooler check it .if oil is found .drain oil in intercooler .you have an oil leak from the turbo this is why you will have light on far left of dash
