Reply to "Dropped a valve..."

Overall ... I see a pattern .. rocker arm failures too high spring pressures ... check the valve spring pressure recommended by the manufacturer of the cam and to rocker arms and compare to whats installed. If thats all fine then I would say human error with the wrongkeeper etc. Remember there is only a few here who need motor jsut for 5000 miles the rest of us who like 75k miles on a motor so Solid roller cams , high spring pressures, on the street are all short term engines.
