Valco Assembly Lubricant

Valco Cincinnati Assembly Lubricant: Engineering Protection from the Inside Out

When an engine is being built or rebuilt, the moments before the first drop of circulating oil reaches critical components are the most vulnerable in that engine's life. That's exactly why Valco Cincinnati developed its flagship assembly lubricant line — to ensure every bearing, cam lobe, and journal surface is protected from the very first crank.

Valco Cincinnati has been an American-made industry leader in engine assembly chemicals since 1952, and their reputation is built on one core product that professionals swear by: GelLube. Originally formulated specifically for engine assembly, GelLube has earned a devoted following among some of the most demanding builders in motorsport.

What Makes GelLube Stand Apart?

Most assembly lubricants are either too thick to penetrate tight clearances or too thin to stay in place during the build process. Valco's GelLube solves this problem with a unique liquid-to-gel transformation technology. The lubricant sprays on thin and penetrates quickly — then transforms into a heavy-duty, load-bearing protective gel within seconds of application. Once converted, GelLube does not drip, melt, or shift from the treated surface, keeping coverage exactly where it was applied.

This behavior makes GelLube especially valuable for components that are difficult to reach or re-lubricate once the engine is assembled. It bonds to metal surfaces and fills microscopic spaces and crevices across a wide range of critical components, including:

• Valve springs and valve train components
• Camshafts, cam lobes, and lifters
• Crankshaft journals and main bearings
• Pistons, wrist pins, and rings
• Rocker arms, timing chains, and oil pumps
• Transmission assembly components and gear boxes

When the engine fires for the first time, GelLube's formula blends seamlessly with the motor oil, providing continuous protection through the critical break-in phase without leaving any harmful residue behind.
