PERMATEX ENGINE ASSEMBLY LUBE 4 OZ

This Permatex 81950 is a 4-ounce container of engine assembly lubricant. It’s made with a special formula that stays put on metal surfaces, helping to protect critical engine components during that crucial first startup after assembly. Think of it as a temporary, thick oil that coats bearings, camshaft lobes, and cylinder walls, ensuring they don't run dry before your engine’s oil system can get fully circulated.

When you're putting an engine back together, whether it's a full rebuild or just a refresh, the initial moments before oil pressure builds are a high-risk time for wear. This lube is designed to cling to those parts, providing a solid barrier against metal-on-metal contact. It's a well-known product among mechanics because it simplifies the assembly process and adds a layer of protection that can make a real difference in the longevity of your freshly built engine.
