Does it get worse if you slow down with engine braking?
The low pressure exerted on the rings during engine braking can allow oil to pass by.
If it does, then it may probably be worn or damaged rings.
If it stays fairly constant, then it may be valve stem seals.

Might just be valve stem seals then.
You could have a shop do a compression and leakdown test to see if there's a difference in compression between the two cylinders.
If the compression and leakdown test fails, then you've got bad rings.
