Yes watching cam deviation and it would go from -5 to +5 rapidly. Bank 2 was not effected at all, only bank 1.
Your observations - if correct - are going to open up a large can of worms.... though cam deviations fluctuating from -5 to +5 deg because of the DOF to the bearing doesn't make sense to me !
Oil starvation to the cams and valve area - if that's what is happening - would certainly cause a noisy top end rattle.
When it first came on the market, there was a lot of discussion regarding the DOF oil supply taken from one of the ports in the cylinder head, some (IIRC Raby being one) advocating that this was the wrong area to take the oil feed from and you were robbing Peter to pay Paul.

Quite a number of people on this site has had the DOF fitted, so its going to be interesting to see the response and outcome of your comments.......
