Ep 6. Free Valvetrain Tuning

In "Engine Masters" season 5 episode 6, titled "Free Valvetrain Tuning", the team takes on the challenge of optimizing engine valve operation without spending a dime. They explore different techniques for maximizing performance without shelling out money for aftermarket parts. The episode focuses on the valvetrain system, which controls intake and exhaust valve opening and closing and is a crucial component for engine performance.

The team evaluates various aspects of the valvetrain system and identifies ways to improve it. They start by inspecting the geometry of the rocker arms and pushrods to ensure that they are correctly set up. They then move on to inspecting the valve spring pressure to make sure it is within spec and evenly distributed across all the springs. They also consider using a shim under the valve spring to adjust the pressure.

Next, they focus on the lifter bore clearance, which can affect the valvetrain's performance. The team shares how wider clearances can affect valve timing, leading to a reduction in engine power. They then discuss how to measure the clearance and make adjustments as needed.

The team also discusses valve lash, which is the gap between the rocker arm and the valve stem. They explain how a larger gap can lead to a loss of power, while a smaller gap can damage the engine's components. The team then shares how to correctly measure valve lash and make adjustments as needed.

Throughout the episode, viewers learn about different techniques for tuning the valvetrain system to optimize engine performance. The team focuses on using free or low-cost methods for optimizing the valvetrain, making this episode an essential resource for anybody looking to tune their engine without breaking the bank.

Overall, "Engine Masters" season 5 episode 6 delivers an informative and engaging look at valvetrain tuning. It offers valuable insight into engine performance and provides practical tips for tuning the valvetrain system to optimize power and efficiency. Whether you're a seasoned mechanic or a car enthusiast looking to enhance your understanding of engine performance, this episode is a must-watch.
