Cam lift and timing can put the valves dangerously close to the piston. We show you how to check the clearance In all but most the mild engine builds, taking extra time to check piston to valve ...

Give them the results of a TDC valve-drop static clearance test, and Comp Cam's techs can calculate the piston-to-valve clearance for any of its cams at any degree of rotation. This is especially ...

Manufacturers like to use a lot of acronyms on their cars. Variable valve lift (VVL) and variable valve timing (VVT) are two of the most popular ones. These systems sound pretty similar, but what do ...
