I own a 780 turbo. About a year ago, I had the seal on my oil filler cap replaced because oil was leaking out of it. Just a few months ago, my heater hose broke; I replaced the heater hose, as well as some questionable hoses connected to the PCV system. A few months later, oil started appearing on the garage floor. The oil appeared to be coming from the intercooler, which I removed slightly under a cup of oil from; no major oil has appeared in the intercooler since- the leak mysteriously disappeared. Another leak appeared just a few weeks later, which I could not locate. I took it to a garage, who claimed to replace the distributor seal. The leak re-appeared again. At about this time, I also noticed that there was a very small amount of oil appearing in my coolant. Frusterated, I took the car to the garage once again, and they said they couldnt find anything wrong, and "flushed the PCV system". The leaks disappeared for a few days, and then re-surfaced. I changed the oil about a week ago, this time using gunk motor flush to try to rid myself of anything that could be clogged in the oil system causing all these seal failures. This morning I woke up in horror to find what was probably 4-5 ounces of oil on my garage floor (the car went for a week with no noticable oil leak problems). At this point I dont know what to do, Im told that the head gasket is in tact, and I can find no indication myself that it is not. To me it seems that all these problems must be related to oil pressure, but no garage or other entity can explain why or where this is happening. What could possibly be causing all these problems?!
