She has a reman'ed long block, and runs quite happily (for a total of maybe 20 seconds at idle), but the valvetrain are terribly loud. Being a fresh build, there is no residual oil. IIRC, the valves are hydraulic and self adjusting. Is this just a case of the valves haven't had time to adjust? I'm running cheap dyno oil for the first 100-200 miles for break in. I'm a big fan of Lucas, but don't want to disguise the symptom.
Any and all help appreciated.
