The mechanical lash assembly can be between the top plunger and the leak down plunger. The mechanical lash assembly can include a shim abutting the top plunger, a spacer, and a spring pressing against the spacer and the shim to form a gap between the top plunger and the leak down plunger. The lash adjuster can include the spring pressing directly against the spacer and directly or indirectly against the shim.
