Engine Comparison (M103 vs. M104)
I just bought what seems to be a nice 1990 300E for my wife. This will be the first Mercedes we have owned with what I understand to be the M103 designated engine. Previously, I have had two E320’s (1995 & 1997) that had the next generation six (M104?). I really liked both cars, especially the 95; however the engine in both cars leaked oil around the timing cover and head gasket.
Was this common to that engine? Will the M103 be prone to the same? How do the engines compare in other maintenance areas and in performance?
