not good news today, i spent almost an hour and a half trying to single out a pulley by spraying WD 40 and listening with a stethoscope but couldn't single out a pulley. i finally pulled off the belt to try one last time with no belt and i heard it. at 3000 rpm you hear a clattering sound at 3000 rpm. the other night with the belt off i didn't hear it but today heard plain as day with the belt off wondering if it can be a collapsed lifter or a chain tensioner or a chain guide broken. I already changed the ims bearing about 2000 miles ago to the LN Engineering ims bearing. at that time the rear main seal sprung a big leak so while changing that i decided to change the intermediate shaft bearing, glad i did because it had already lost all its grease and the balls looked scored and it didn't spin smoothly at all. the motor has 42000 miles on it. now what?
