Tec4 Top End Treatment is a highly concentrated chemical formulation engineered to clean, lubricate, and restore quiet operation to upper engine components. Designed specifically to resolve sticking hydraulic valve lifters (tappets) and variable valve timing (VVT) actuators, it neutralizes harmful engine varnish, sludge, and lacquers that restrict oil flow to critical top-end parts.

Formulated with advanced anti-wear additives and high-detergency agents, Tec4 Top End Treatment cleans micro-passages without altering oil viscosity, protecting sensitive valve train components during high-rpm operation and extreme thermal cycles.

Key Performance Benefits

• Eliminates Lifter Noise: Quickly frees sticking hydraulic valve lifters (tappets) to restore quiet, smooth engine idling.
• Restores VVT Performance: Dissolves varnish and sludge deposits from Variable Valve Timing (VVT) solenoids and oil control valves.
• Cleans Micro-Oil Galleries: Unblocks restricted internal oil passages supplying the cylinder head, ensuring instant lubrication on cold starts.
• Anti-Wear Protection: Contains polar anti-wear additives that reduce friction and heat on camshaft lobes, pushrods, and valve stems.
• Prevents Gum & Lacquer Build-up: Neutralizes acidic combustion bypass products to stop harmful lacquer formation on hot metal surfaces.
• Viscosity Safe: Will not break down or thin out motor oil shear stability; remains active until the next service interval.
