Well the good news is that the Sprite passed the MOT yesterday after the
15-year rebuild. I have done about 15 miles so far and have noticed clouds of stuff coming out of the top and bottom breather pipes (which go into a 1.5 L catch tank). I reckon it will do this until the rings are bedded in, but there is a lot of oil being blown out of the filler cap and running down the engine. I haven't noticed this on a rebuilt engined before. Will it settle down or is there something wrong? I have done all the usual things - checked ring gaps, put the rings on the right way round, used a pukka ring compressor when inserting the pistons etc. Oil pressure is 45 psi hot at idle, 60 at 2,000 rpm, so nothing wrong there. Any ideas?- posted
