I put the crank in, set the thrust bearing, torqued all the main caps, and then realized I used the wrong assembly lube. I used ARP assembly lube and the engine builder who set the oil clearances used Driven assembly lube. I was planning to take all the nuts off, clean the studs and nuts (without pulling the caps), and then retorque with the correct assembly lube. My question is, do I have to go through the process of setting the thrust bearing again? Thanks!
I agree - I can't imagine it would be outside the margin of error. To put your mind at ease, you can always check the posted torque figures by ARP and Driven for the same bolts.
Like Hugger said, leave it alone. IMHO, loosening everything then re-torquing will do more to upset everything than using the slightly different assembly lube.
Agreed! Using ANY assembly lube is going to give better results than doing it dry. Even basic engine oil will be better than dry.
I was hoping that was going to be the consensus. I was just concerned that since oil clearances have a tolerance of +/- a few 0.0001”, that even a minor difference in stud stretch due to the use of a different assembly lube would result in oil clearances outside the acceptable range. As always, I appreciate all the responses! I will proceed with the build as is. Jim
