Mercedes-Benz 300SL ProblemsHard/Soft Tops May Develop Problems Due to Age
As vehicles age, various problems may develop with the hard and soft tops. If problems are encountered, it would be recommended to have a technician familiar with these tops perform the diagnoses.
Internal and External engine oil & coolant leaks can develop from the head gasket and/or timing cover gasket; these leaks should be repaired before the engine oil and coolant intermix which can result in severe engine damage.
On high usage vehicles, the ignition lock may become difficult to turn due to wear of the ignition lock and tumblers. Replacement of the ignition lock cylinder will generally be required to correct this concern.
