Additional Information

Assembly Lubricant Usage
Engine assembly
Fastener installation

Because of frictional inconsistencies with oil, moly, and other lubricants it takes multiple cycles of torquing the bolt, loosening it, and tightening it again to obtain the required preload or stretch. Typically, when a fastener is first tightened, friction is at its highest point and the preload value or stretch is low. As the fastener is cycled numerous times the friction decreases and the preload increases. This phenomenon is called "preload scatter." With this ARP Ultra Torque assembly lubricant, a fastener need only be torqued once to get within 5 percent of ideal preload, and it remains consistent through all subsequent cycles (from race-prep machining through final assembly). Moreover, given the inconsistencies of ordinary lubes, it is quite possible for adjacent head bolts or studs to have vastly different preloads. This scatter causes bore distortion, hampers piston ring seal, and leads to poor head gasket sealing.

Kinda pricey

Summit RacingSummit Racing Verified Purchase

ARP recommends that all torque applied to engine fasteners is done with lube applied (wet-torque). Having no experience, I went with ARP's recommended lube. Not sure I would spend the money again, with other assembly lubricants out there, but no problems with multiple assembly and reassemblies. No coking or freezing up.
