Okay, after replacing the cracked head, suddenly, it is knocking. It would go away
After it warms up, but it took a long time to go away. My neighbor, whom does not talk to me since my wife complained about his dogs keeping her up at night, doesn't talk to me anymore. Before that happened, he suggested it was the connecting rod bearings. Suggested just replacing them with a standard size and it should be good to go. Finally, I get around to doing it and as I am working on it, I notice cylinder 1 piston seems to be making a noise. So, now I'm wondering if it is the wrist pin? Hopefully I can link the short video. It's hard to tell where the sound is coming from in the video, but it sounds to me, like it's the piston slapping against the cylinder wall or something. I'm not sure.
