Cleaning black soot is as simple as using a carbo clean. Hundreds of times, without fail.
It is not a caked-glazed overheated plug.

Problems with ignition can also lead to inefficient burning.

It is unfortunate that other refrigerants cannot be added to an R-12 system. Fortunately, R-12 is still accessible. The challenge will lie in locating a technician with R-12 gages who can inspect your system for leaks and other issues. Assuming the system can be converted, I would inquire about ...

It appears that there was a change in output midway through the year.

Verify the 500SL's production date. Before September of 1982, it could have been an 82 model. Might Nobby's 83 have an 82 build date before September?

The rear brake service indicator must be reset using a scan tool. As a result, your iDrive will display a new "generic" mileage countdown.

Changing the wear indication on the inner pad isn't strictly necessary unless it hasn't triggered yet. Nonetheless, I believe it would be extremely ...

When you're wading, you may seal the axles, gearbox, and transfer case with the breather to keep water out. Without the breather, the seals would be blown due to the pressure caused by the heat within the components. All of the breather hoses are looped around at the top of the bulkhead to prevent ...
