Message	The issue is though that when deactivating all the cylinders with the power balance test, all but Cylinder 3 drop the RPMs by 400-500 RPMs. When Cylinder 3 is deactivated, sometimes 0 RPM change, other times only 20 RPM change. That coupled with the noise, and low compression on 3, is why I was thinking a deeper issue. Guess I just need to troubleshoot more, thanks for feedback.
Follow Ups	Got project running, but it has low compression. Need advice - Polishzx 18:34:36 02/24/20 hard to tell in video, but sounds top end to me - Stanky (BC) 20:35:32 02/24/20 Yeah it is tough to pick up, but it is fairly loud - Polishzx 22:27:05 02/24/20 How long was it sitting for?

(n/m) - Bernie (NoVA) 13:38:17 02/25/20 I can try again with a smaller amount of oil - Polishzx 14:01:56 02/25/20 I'll definitely try it, thanks for feedback - Polishzx 14:01:21 02/25/20 Agree. Does sound like bent rod clap. See video in comments - volcomstone550 05:53:04 02/26/20 Based on your diagnostic work (well thought out and - SirpriZ 14:25:23 02/25/20 If its a bent rod you can fix it relatively easy. - volcomstone550 05:59:54 02/26/20
