has anyone ever have one of these go bad. The passenger side of my engine is soaked in oil (all over my belts, including timming belt) and I was wondering if this was a tell sign of the intermediate shaft seal going out I really can't pin point the leak right now with everyting in the way. First I had a leak in the valve cover (in the back, dripping on the manifold causing smoke in the engine bay) that got worse when i was under boost so I resealed it and let it sit overnight and when I drove the car to work the next day I opened the hood and there was oil on my pulleys. Its an 85 turbo z with a one piece intake manifold.
