What Is ZPaste?
ZPaste™ is a new class of ultra-high film strength cam assembly lubricant. We designed it 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 our 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.
