I tore down the engine today and found a broken push rod, a valve tip with a bad wear pattern and no real indication as to why the engine was smoking. Here are a couple of photos but I started a thread in the engine section asking for help getting to the bottom of what has happened.
Photo 1 is how I found the valve train when I pulled the cover
Photo 2 is how I found the push rod
Photo 3 is damage to rocker stud
Photo 4 is the headers right tube oily left tube is showing a cylinder that is running rich.
Photo 5 is #4 & #6 intake ports on head. No sign of oil being sucked from the valley.
