Hello all! Hoping you folks can help me figure out my problem with a 4.6 stroker that I've built. After the first assembly there were no issues with the break-in process which followed the cam manufacturers directions using comp cams break-in oil and lube. I did the normal easy break-in driving for about 50-75 miles around town and then drove it to work, 50 miles one way. When I started it up after work it was knocking. The knock doesn't go away with time or heat, it gets quieter during running but slowing to idle it's there every time. I got it home and immediately tore it back down
