I've been having a few problems with my 99 Si with GSR Motor, Oil in Intake, Black Smoke in VTEC, and Oil Loss. I'm going to go for what I feel is my gut feeling and say its the PCV System.

Is it possible to remove the stock PCV System, and install a ventialted catch can using the stock PCV location and fittings? If no, then what are my best options without having to drill into the oil pan or tap the valve cover.

have you cleaned or replaced the PCV valve?

you can use the vibrant oil cap no weld method or just do it the right way.
