My LS3 is starting to smoke a little bit at cold idle and recently fouled the spark plugs after a few hundred miles. Smoke is from both sides and all spark plugs were fouled evenly, so I don't think its valve seals. When I looked in the intake it had puddles of oil in it. I'm hoping that maybe it's as simple as the way I'm venting the car is drawing too much oil into the manifold and getting caked on the valves.
Right now I run the valley cover snout to the fitting on the intake manifold after the throttle body. I run the the passenger valve cover fitting to a fitting welding onto the intake tube after the MAF.
Instead should I run the passenger valve cover fitting to a catch can vented to atmosphere? Or will that introduce unmetered air and mess up my tune? Or should I run the passenger valve cover fitting to a sealed catch can and from there run to the fitting on the intake tube after the MAF? Or something else???
