Valve Adjustment on a 1977 Opala: A Quieter and More Powerful Engine 🔧 In this chapter of the mechanical restoration of our 1977 Chevrolet Opala, we show the complete step-by-step process of valve adjustment (clearance adjustment) — the procedure that prevents that "ticking" sound in the engine, loss of power, and high fuel consumption. Here at Vida de Opaleiro, we document, without cutting out the challenges, each stage of the restoration of our 1977 Opala: engine, electrical system, suspension, and everything else that comes along the way. In this video you will see: Why an out-of-adjustment valve causes that characteristic noise and what it can compromise if ignored How we check the correct clearance before starting [specification used / reference manual] The step-by-step adjustment with the engine [cold or hot — confirm according to the video method] The tools used: shim set/feel gauge, spark plug wrench [complete with the actual tools shown] The result: engine running smoothly, before and after adjustment 🎬 Watch the complete series of the 1977 Opala restoration: https://www.youtube.com/@VidadeOpalei... ⬅️ Previous video in the series:    • Troca de Radiador, Alternador e Prisioneir...   🔔 If you are also passionate about Opala and classic Brazilian cars, subscribe and turn on notifications — there's a new restoration every week here. #Opala77 #ValveAdjustment #OpalaLife
