I have a set of CAT roller tip rockers on the 289. Have had them on there for 2 weeks. Well, last week, the nuts holding down the rockers started to loosen up. I retightened them up today, but after 5 minutes of driving they loosened up again, and made that loud squeaking/ticking noise.
Does someone like ARP make a set of good nuts that i can swap in? Should i make sure there's no oil on the bolts when i tighten them down, or does it matter?
