What is this noise? Xr275 cam. Full exhaust and monster clutch.Noise only occurs when car is up to full operating temp and is more noticeable at idle and on deceleration at lower rpms. Has hardened pushrods. When cold no ticking just normal piston slap. As car is warming up and piston slap goes away it is quiet. Then as car reaches full operating temp it has a tapping ticking noise that is intermittent. I am leaning towards failing lifter needles Video included
