Default Re: oil leak on 59 A

Ya it is dripping just siting on the engine stand, which surprised me, visioning that I have to pull it apart again. Engine was not started after rebuilt. I was hoping for something what "alanwoodieman" said. Thanks. Ya, in the old country, we always filled rebuilt engines full of 10w oil, if they would be stored, so sorry if I didn't explained my self properly! This is my first flaty so I am not to familiar with rope seals. Didn't think that the oil gets by the seal, but I noticed, there is a spiral cut in to the crank to force the oil back in to pan, when engine is spinning. I also noticed, that when I was priming the oiling system, before installing oil pan (I use chevy 350 oil pump with drill) that there was lots of oil leaking round the base of oil pump, where it meets the block. So I installed "O" ring in first grove at the top of pump, which fixed the problem and gained 7lbs of oil pressure!
