I have taken my car to a subaru service dept for this issue , so i am just looking for feedback . about 6 months ago I was doing a rad drain and fill ( I do it around every 6 months with a full flush once a year ) anyway when I pulled the cap off the radiator I found little oil spots in the coolant . I decided to check the overflow tank and there they were also . So I take the car to Subaru and they do a leakdown and compression test and say they find no problems and that the spots are normal . Well 6 months later and after I do a flush and thermostat swap before I put the rad cap back there they are again . I have no problems as far as overheating , and I dont see any coolant or moisture in the oil . So what gives ?
I am planning a turbo kit in the next 6 months or so but i would like to resolve this issue befor then . BTW the only engine mods i have is an intake and exhaust . Castrol syntec ever 3000 then every 2500 after 50000 miles the car has 66000 right now .
