Quoting myself - thats not correct. Pulled the cams to do the clearances to day and found the cams are hollow, with passages where the bearings are.(and plugs in the ends) Pressurised oil gets to the left side caps, passes into the centre of the cams then back out the holes at the right side caps. The right exhaust is still the last place to get oil, though.
