Mysterious engine oil leak

[davidwheeler]

I was distressed by a substantial leak from the front of my newly built engine.   I took off the radiator and found (eventually) that oil was being flung from the front but not the back of the crankshaft pulley.  The oil was tracking along the crankshaft inside the pulley sleeve and has been successfully stopped by a fibre washer under the crankshaft pulley nut.   Thus ended many days of puzzling!

I just thought you'd like to know.

Having just had another look, I suspect that the primary leak is from the end crankshaft oilway plug.  I have just done the fibre washer again though as it works and is easy.
