Turbo Seals Going?
Hey guys, so I picked up my 02 7.3 about a month ago and since I bought there seems to be an oil build up on the outside of both intercooler pipes right near where they meet the y-pipe near the turbo. I figured it was normal since it has 193k miles, but my buddy at school says the oil on the pipes is from my turbo seals leaking and that his are going as well in his 01. I also noticed that the truck seems to have some trouble when going up hills and sometimes when driving up inclines the engine makes sort of a hissing noise, so I figured maybe there is something wrong with the turbo. I don't know exactly where the turbo seals are located or what they do, so I was wondering if my truck is showing some symptoms of them leaking. Also, if they are leaking, how hard is it to fix and what am I looking at in terms of cost?
