Most seals (gaskets) are elastomeric materials and are found throughout the engine. They keep the oil inside the engine while allowing mechanical motions to run through the engine from inside to outside i.e. the crankshaft and allow access to engine components.

Heat and time harden and shrink seals so that over the years oil weeping becomes a common occurrence. CamGuard nullifies these effects to keep seals supple and doing their job.

Certain additives, found in some commercial oils and additives, can break down and lead to seal degradation and need for premature seal replacement. See Figure 1. CamGuard mitigates this problem by blocking aggressive chemical attack.
