rocker chatter

  • Sponsors (?)

Stock ported e7 heads oversized valves, tfs stage 1 cam, stock pushrods, stock rockers and they will not tighten down and chatter like crazy:shrug:

The TFS Stage 1 cam is probably ground on a smaller base circle than the stock cam, which means that you're gonna need longer pushrods to get the correct lifter preload. Buy a pushrod checker so you can find out which length pushrods you'll need.
yeah that is what I thought, I had a set of 1.6 rollers that tightened down with no movement but wouldn't clear my valve covers so I sold them and tried to go back stock but ran into this problem, now I have found a set of ford motorsport 1.6rr has anyone ran these with stock valve covers.
