Camshaft Lobe Lift

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. To check the intake and exhaust lobes, measure across diagonally (A-C) and across horizontally (B-D). Subtract (B-D) from (A-C). This will give cam lobe lift. Install a new camshaft when cam lobe lift wear exceeds specifications. For additional information, refer to SPECIFICATIONS .
