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.
