I am trying to determine if I am having lifter issues or if it is simply the roller rockers are noisy. When I first start the engine and it is cold the engine runs quiet. As the temp comes up it starts to tick and as it gets warmer it gets louder. It goes away when the rpm's come up. I have never ran roller rockers so I am unsure if it is just them I am hearing. I have adjusted the valves 4 times and checked all the clearances with the rockers and they are not making contact with anything.
