After changing my oil, i noticed a knocking in my engine. I found the knock in the valves over the 7 cylinder. I change my oil regularly and add a quart of lucas heavy duty oil staybalizer. Should I take it in to get looked at. And how much stuff should i remove before i take it in. do i need to remove my gauges since if i remove my banks tuner, they will not work. and how about my EGT probe.

I would take anything off that looks like you had a reprogrammer in the truck cuz like I said in a previous post the service manager said if they see a reprogrammer on the truck it voids the warranty.
