    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

    Just had our 2005 CLK 320 serviced for 1) oil change and 2) brake fluid changed, and the shop stated the following:

    "PCV PLATE RE SEAL NEEDED $175.00 (PCV PLATE IS PLUGGED UP AND LEAKING OIL"

    Wondering if this is something I can do myself. Appreciate any advice on this.

    Oil leaking from valve cover area - relatively minor leak, but some smoking. About $320 to fix.
