    Kept smelling burning oil every once-in-awile. Researched and visually observed very small seepage from the inspection plate while car was running. Did not seep while engine not running. Bought the gasket online for $10. 30 minutes labor in my driveway. Spilled about a half cup of oil when I removed the plate. Smelled burning oil for a while afterwards because the oil leaked down into every crevice possible. No smell for almost a year now. Oil level constant
