2011 C200 Travel Ventilation Door Chamber Gasket

September 14, 2024

The M271 needs to replace the door cushion. Recently, after stopping driving for a long time and then starting, blue smoke came out of its butt. After replacing the screw on the turbine, it still hasn’t been solved. The car was bought and only replaced with brake fluid, air filter, and air conditioner filter. I bought ngk4 spark plugs at the E-commerce Festival, and I used tools to remove the ignition coil and spark plug at night. There is some oil on the third coil, so it is basically certain that the valve cushion needs to be replaced. The oil seems to be seeping into the cylinder along the thread of the spark plug to participate in the combustion (logically speaking, it won’t seep into the combustion chamber?). The oil filler port is also oily. Today, I can only clean the spark plug with Dafeng nx500 and carburetor first, and I can do the valve cushion another day. There is a lot of carbon deposits on the end of the spark plug, and the combustion chamber looks like a lot. In the future, prepare to take small doses of additives for a long time. Please ask Yan Ban for help in consultation
