July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Valve Clearance

Engine is equipped with hydraulic valve lifters. No adjustment is necessary.

If lifters are replaced, DO NOT  start engine for 30 minutes as valves may hit pistons. Lifters must be allowed to bleed down before starting engine.
