The M102 is quite reliable - CIS is / can be a problem as explained above
Additionally
Head gasket trouble - corrosion between alloy head and steel block
A particular problem for the M102 fitted to W123s - simplex timing chain. Not known for being reliable. The (double row) duplex versions are much better.
