I checked the pre-load a couple of times prior to this. That cam as always been a bit noisy. It's certainly possible that could be the cause. I'll definitely have the opportunity to set it with the intake off this next time.

It's also probably worth mentioning that the #5 cylinder also seems to have an oil consumption problem. The plug fouled-up with oil. I did a compression check to find that cylinder 20 psi lower than the others. That could be attributable to the reduced intake lift. Before I found the wiped lobe, I was leaning towards re-ringing that cylinder.
