I called Molnar to get some specs for when I reassemble my short block. In the conversation I asked about what lube to use on the ARP 2000 rod bolts that are in their rods I have. He stated that while working at Oliver they discovered that the ARP lube had a lower and lower release torque after torqueing, unbolting and then retorqueing the bolts. He state bolt stretch was always consistent but the ARP lube caused a lower release torque number. He recommended I use an EP#3 grease as it will dissolve and maintain a higher release torque. He said with ARP lube the bolts kind of smoothly glided loose when taking them apart and with the EP#3 grease they would "snap" at first when loosening them. I don't mean the bolt would snap/break, but they found they would have a much more consistent release torque. Remember, I am just a knucklehead hobbyist trying to paraphrase and pass on what I think may be good info to help others. I have built a number of motors in the past using ARP lube on their bolts and never had a failure so I assume the info I got from Molnar is geared for high end severe use race motors. If any of you use EP#3 lube for your rod bolts, do you have a recommendation? Thank, Jim
