sherman lifter help

Bobby Fazio · 03-24-2014, 10:12 AM

Made 4 really good passes with the mustang 5.0 and after the fourth pass I heard a noise going through the finish line, sounded like a quick rev limiter bounce (but I had no rev limiter set that low) going through at 6500. Was making a bad noise driving up return road, I pulled the valve covers and noticed 5 roller rocker adjustment nuts had backed off almost completely. Tightened them back down but the car didn't run anything close to the previous 4 runs. Did I lose a lifter? Compression test passes and didn't see anything wrong with springs or pushrods when I pulled them out. Rockers weren't damaged, just loose.
