If those are indeed holes, they would be poking into the right side rotor shaft access hole as I described above. If memory serves, these are sealed holes from the back face of the blower. Unsure if that'd make a difference or not. Doubt it. If those holes aren't sealed then I suppose it could cause a small oil leak behind the motor or perhaps a tiny vacuum leak in the right circumstance. Still seems like something that a dab of JB weld would fix without too much problem.
