ZPaste is a new class of ultra-high film strength cam assembly lubricant. Designed after receiving requests from engine shops which were experiencing high amounts of early cam failure after an engine build. ZPaste kept a film of lubricant on the cam lobe longer than any other assembly lube in testing, and encouraged the growth of a ZDDP anti-wear film. After the 5-minute point, all the lubricants other than the ZPaste showed greater friction and resulting temperature rise. This indicates that the unique film properties of ZPaste allowed it to establish an effective film which displayed stable anti-wear characteristics. You can be sure ZPaste will protect the lobe in ANY normal break-in scenario until the engine break-in oil begins to gradually wash it off the cam lobes. It is important to note in all cases, regardless of what lubricant you use when assembling your flat-tappet cam and lifters, adequate ZDDP must be present in the break-in oil to ensure proper break-in, as well in each oil change thereafter. ZPaste helps here as well, when applied at approximately 1 gram per lobe and fully dissolved in the oil, it will contribute a useful 65 ppm of phosphorus in the form of ZDDP to 5 quarts of oil. 5/8 oz (17.72 grams) packet
