Spun two bearings. I heard the oiling proiblem is all in the crank. I put the Y7 crank next to a A6 one. The A6 oil holes point straight up while the Y7 holes are about 30-40 degres away from up. If I use a A6 crank do you think that will solve the problems? Other than the crank, both A6 and Y7 blocks looked identical on the inside.
