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
lober motors in Chicago Lincolnwood said it was the velvel cover leaking replace the gaskets
Change the head gasket cover the driver side is leaking oil
Small oil leak in front of engine problem not resolved
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.
told it was a cracked valve gasket cover
