Valve Spring Squareness

WARNING: This page is about a different car, the 2010 Ford Pickup, 2010 Ford F550 Super Duty, 2010 Ford F450 Super Duty, and 2010 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. Clean all valve springs in a suitable solvent.
  2. Inspect valve springs for rust, pitting, distortion and cracks. If any of these conditions exist, install new valve springs.
  3. Verify that the spring ends are flat and square to prevent lateral loads on the valve stem. Install new valve springs as necessary.
