Okay i'm going to try this again. This time i'm going to include all mods and hope for the best guess. My 03 WRX is smoking some after warm up. It has never done this before and the short block was replaced about 1 1/2 years ago because of stupidity. I have a Ecutec piggyback with stage 2 program, an Invidia V3 downpipe, Bosal catback, deleted up pipe cat, AEM short ram, STi intercooler and a MBC set at 15.5 lbs. I checked the intercooler for oil and there was none. Hopefully I can get some ideas.
