Is it the original intercooler? If so check the underside of it for wet oil deposits. The original IC's are well known to leak and if you see oil on it, its leaking. Throw it out and replace it. This could be your oil leak issue. Rocker cover gaskets not so much. Injector seals or glow plug seals more so.
