Depends on what your definition of cleaning is.

The instructions are very specific that you only do a gentle wash of the outside of the lifter. They don't want them taken apart and they don't want aggressive cleaning around the wheel as they have their own lubricant packed into the bearings that they want there during initial start. They did say soaking in break in oil for at least 2 hours was acceptable and preferred.

So that's what I did, a gentle outside wash, don't blow with compressed air. let air dry and then soaked for a few hours in brad penn 10-30 break in oil.

This is how I've treated every hydraulic roller lifter without issue. I have always taken the Johnsons or Hylift Johnsons, gave them a gentle bath and soak in break in oil. Install and go.

To add, I've changed the oil 4 times now in this engine. Initial run and tuning, then a short 30 mile drive and dropped the break in oil. refilled with more break in oil and drove roughly 500-ish miles and changed oil again to some ZR1. Drove another 800 miles and changed oil again this time with some Amsoil that is going to stay in the engine. So far that oil has about another 1300 miles on it I've cut the filter every time and other than the initial run in where I expect to see some metallic from break in, the filters have been very clean and oil looks good. Not using any oil and running really nice, but still a lifter bleeding down after it sits a few hours. The sewing machine noise I can live with even though it's louder than my solid flat tappet lifter engine LOL. But because of the bleed down issue I'm just swapping them out for Johnsons.
