Just started. Sounds like a dull thud after I let off the gas. (Screwdriver handle tapped on the valve cover type noise) just one thud, not consecutive. Valve train rocker is somewhat loose on the #6 cylinder. Wish I could upload the video...
318 with a thumper cam.
How long do you think it will last. I'm shopping for a rebuild of this engine and or upgrade right now.
