I've used a half quart of ATF mixed in with the engine oil to resolve lifter ticks in the past. It works well to dissolve deposits. Clevelands are known to bend pushrods, which can also cause a tick. You can check them by spinning each pushrod between your fingers. If the rocker moves side to side, the pushrod is bent. </p><p></p><p>Your rockers are bolt down style from the factory.

Lots of issues with today's lifters failing and not being machined properly, or poor metallurgy.</p></blockquote><p></p>
