The arrangement includes at least one exhaust valve and a support arranged adjacent to the at least one exhaust valveand configured to engage a lobe defined on a camshaft. A lost-motion hydraulic lash adjuster (LMHLA) is positioned within the support, and the LMHLA is configured to adjust lash between the support and the at least one exhaust valve. An engine brake system is configured to engage the at least one exhaust valve, such that: (i) upon activation of the engine brake system, the engine brake system engages the at least one exhaust valve to open the at least one exhaust valve; and (ii) upon deactivation of the engine brake system, the engine brake system disengages the at least one exhaust valve such that the at least one exhaust valve is closed.
