A hydraulic lash adjuster mechanism for an internal combustion engine, the adjuster having a body with a bore formed therein, a plunger slidingly received within the bore, and a high pressure chamber formed between the bottom of the bore and the plunger. The plunger has a fluid chamber formed therein to receive engine fluid through an inlet opening and is in communication with a first check valve mechanism for regulating the flow of fluid from the fluid chamber through a valve opening into a high pressure chamber. A leak path allows fluid to escape from the high pressure chamber due to increased force on the plunger. The high pressure chamber is in communication with a second check valve mechanism for allowing fluid to leak from the high pressure chamber at an increased rate in response to increased force on the plunger.
