Hi, I'm a newbi from Philly, I have a 2006, 5.7L Hemi 300C with 94k miles. I've been experiencing an oil burning smell and can see smoke 2-3 minutes after cold starts rising from the exhaust manifold just below the valve cover gasket on the passenger side back closer to the fire wall. Not sure if this is a valve cover gasket leak. I never see any oil on the floor and nothing collects on the plastic shield under the engine. Everything looks dry. I've pulled the spark plug coils to inspect valve cover gasket leaks in each plug tubes and all is clean. Could this be tranny fluid or something else leaking onto the exhaust?
