What is ZPaste™?
The Ultimate Cam Assembly Lubricant is specifically intended for the break-in requirements of flat-lifter engines. When an engine is first re-assembled, even with the most careful machining of the cam and use of the best quality replacement tappets, the rubbing surfaces are still pretty rough (under a microscope you’d see high peaks and deep valleys in the metal surfaces). As the engine is run in, these high peaks wear down, but at the start, all of the pressure is concentrated on a very small part of the surface area. ZPaste™ remains on contact points longer than other lubes, protecting parts from damage during initial start-up.
This is the perfect answer to the current break-in issues. After being dissolved in the oil, the components in ZPaste™ will continue to help protect engine parts during break-in. ZPaste™ is designed to be used along with ZDDPlus™ for initial engine break-in.
It comes in a 5/8-ounce packet, which is enough for one V6 or V8 application. When used in conjunction with ZDDPlus™ (4 ounce bottle) in a normal 4-6 quart oil capacity, no special break-in oil is required.
