Thanks gentlemen, I have not put the #8 intake lobe on the base circle of the cam yet & I definitely need to check it that way. It just looked really odd that ONE adjustment screw was very noticeably "taller" than all the rest of the rocker arms.


IF the snap ring broke on this lifter & that lifter's plunger got stuck up higher than the other lifters (basically making this lifter a taller solid lifter), then it would explain the adjustment difference. My "thought" was that maybe the pushrod on this valve is contacting the base of that rocker arm causing the noise?


It think I may need to get a magnetic tool & slide out that lifter and one more to compare them.


Any more ideas? I will at the very least be re-setting the valve lash on this side of the motor (& likely more)
