I assume my 84 190D (OM601 engine) also has blow-by. It has 253k miles now, quite noisy and oil leaking out from the new oil cap and valve cover gasket. However, one thing I don't understand is, the start is very easy. After the glow plug light is off, the start is instantaneous, not even taking one full second to crank. I thought blow-by means lower compression (yes, its compression is in the low margin). So why is it so easy to start?

Generally, blow-by indicates the piston rings are no longer holding compression - its "blowing by" (the rings) into the crankcase. Usually such motors burn oil and get hard to start, especially in cold weather.
