hydraulic
Here, “hydraulic” means the engine uses parts that automatically take up the valve clearance. If the engine isn’t hydraulic, you may need to measure and set the gap manually.
In this context, “hydraulic” refers to hydraulic valve lifters (or similar components) that automatically manage valve clearance. That’s why the speaker says valve lash info is especially relevant for non-hydraulic valve-train designs.
