Hello everyone,,


I have a '95 850 Turbo and there are a few things I'm trying to figure out. First, which turbo do I have? My engine # is B52334FT and VIN # YV1LW5719S2136846,,,there are different ones I found that were put on 850's. My turbo has a loud humm that is heard inside..it mostly happens when the turbo gauge starts to enter the white section...also I found evidence of oil when I removed the tube that runs across the spark plug cover. So I suspect there may be a problem with the Turbo. Question: Can an internal turbo leak come out to the outside area when boost is positive? Because I've noticed oil everywhere in that general area after the turbo has been used on a 70 mile trip and it shows evidence of oil droppings on the ground from the turbo area. But it doesn't show as much of oil dripping when I don't engage positive boost, just a few oil droppings. I'm thinking about replacing the turbo, but I need to know which turbo I have ie...TD04HL-15G,,,,TD04HL-13G,,, or what???

Thanks a millllllll..
