A rod knock would mostly follow the crank RPMs. I'm thinking that sounded slower, so might be a bent pushrod, stuck valve, something like that. Rod knocks are kind of low thumps, something in the valve train usually gives a sharper tap tap. But, REALLY hard to tell from a youtube video. You might pull the valve cover and see if there's anything obvious, either static or with it running. Jon |

It was definitely a rod knock, one cylinder was MISSING both bearing
inserts. Not sure how it could have happened, the engine definitely was worked on recently. i On 2017-08-30, Terry Coombs wrote: On 8/29/2017 8:06 PM, Ignoramus8901 wrote: https://www.youtube.com/watch?v=6C3OReUPPuQ Would you say it sounds like a rod knock? ??

How do the crank and rod look after that abuse? -- Do not let your fire go out, spark by irreplacable spark. In the hopeless swamps of the not quite, the not yet, and the not at all, do not let the hero in your soul perish and leave only frustration for the life you deserved, but never have been able to reach. The world you desire can be won, it exists, it is real, it is possible, it is yours. -- Ayn Rand |

How long *did* it run, anyway? |
