| bent pushrod and seized valve in rebuild |

| Ouch … A fresh rebuilt 390 w/ hardened exhaust seats installed, valve guides etc done at a machine shop. I followed the 68 Ford shop manual when putting the motor back together. I started the motor and made sure the heads were getting oil. Everything looked fine. I could see the heads getting oil, all the pushrods, rocker arms, and valves moving properly. The other night I started it and let it run at 2000 - 3000 rpm's for 15 minutes. Then I started to hear a steady “ting noise” coming from the head. I removed the valve cover and found a bent pushrod and a seized valve. Any ideas of what I did (or did not do) wrong? Thanks, Scott |
