Re: Valve Springs
Hey guys, just to let you know we pulled the rockers for the spring change and found #1 and #4 intake pushrods broken. How the heck that happened I do not know. Seemed to have broken on the seem at the lifter end, they were still being held together by pressure and never separated from their position. I made at least 3 passes, possibly even 5 because I had valve float 5 passes ago at the top of first gear trying to shift it at 6500 rpm. Could weakened springs cause valve float and break pushrods like this? Thanks for any insight.
