Losing Crank Case Oil Seal question

New Member and didn't see the topic for 150r....

Losing 1/3 to 1/2 Crank oil in hour of run time. It appears that it is moving to Trans oil and then out vent line. I had been advised that the right side crank seal is culprit. So couple of questions for the Docs...?

1. Why is left crank seal not a contributor to the issue ? If it is, can it be replaced without a split case ?

2. Is the balancer shaft seal a possible issue on left side ?

3. If I missed the boat completely in diagnosis, please advise...

Thanks !!
