Ticking right up under the driverside valve cover, gets quicker with rpm, and sometimes you hear a flutter of around 5 in a row instead of just a single tick. I have already pulled the lifters and pushrods out and checked and they looked fine also no loose rocker arms. I have also tried thicker oil please help!
