Frozen rocker arm
 

Slowly but unsurely, as always. I am installing rockers after timing the cams. At even half torque, the #1 exhaust rocker is pinched so tight it won't move. I have tried a few other rocker arms and shafts in that space with the same results. The bores feel smooth, and I don't see any hairline cracks in the cam box.

I'm aware of walking rocker shafts, but searches haven't turned up information about stiff rockers. Anyone experience this? What should I be looking at?


(3.0 stock but for 930 cams, rebuilding due to broken or slipped timing chain)

Rocker shaft alignment? If the rocker shaft is not installed properly (offset to the short side), as you tighten the bolt the rocker will seize.

You got it, Henry. I figured out I had aligned the shaft to the incorrect side, and I was just sitting down to try to delete my post when I saw your reply. When I say "shaft," I mean "shafts," because everyone I tried in there I aligned incorrectly. Maybe I need an alignment. Thanks for your reply!
