I took out the lifters and cleaned them, all the pushrods look good so hopefully this rocker assembly rebuild will be the cure.

My slight upper engine tick turned out to be a tiny vacuum leak, mostly. Exhaust leaks can also sound like a tick.

Mainly, I decided to just live with it, after trying various oil weights. At least it doesn't sound like a diesel anymore. Our lifters should really eliminate any ticks caused by the valve trains.
