I'm close to finishing my build and I'm noticing that the connecting rod cap screws are clipping the engine block on a rotation. Does yours do this? I even dropped down to a m3-8mm flat head screw and even that rubs a bit causing it some stiction at that point in the rotation. Maybe you could release a different engine block model with that part trimmed down?
