Engine A (left below): Lifters ride against the camshaft, pushing the push rod which, in turn, pushes the rocker arm opening and closing the valve.
Picture Point: Lifter
Now looking at Figure 1 with Enginall under 500 x magnifications, you are seeing the coating left by Enginall protecting our lifter from any damage.
Remember, these engines were run together for full horsepower and full load for the afternoon’s testing sessions. If Enginall protected this well under extreme conditions like racers experience, just imagine how well it will do for you under normal driving conditions.
Engine A (Figure 1): Scratches are ON TOP of the Enginall protective coating. There is no apparent damage to the metal part. The protective lubricant is in place. Compare no protection in Figure 2
