Take as many photos as you can of the bottom end such as all of the rod bearings, and all of the sides of the rods as well as the crank journals. The more can the better. I'll bet none of the rod big end sides have any signs of wear. Yet they are the source of the BBQ ticking. This explains also why the 6.2L in the F-350 does the same thing as does the 6.7L Power Stroke. They likely use very similar clearances, especially since Ford builds these engines on their modular engine assembly line.I've asked for more photos, i will take a trip over by the weekend and have a look for myself
They all share common 100 mm bore spacing. Due to production modularity all their engine variant, gas NA, gas FI, diesel FI share commonalities in dimensions. Ford settled on the modular concept back in the 1980's when they introduced the 4.6L and that's why we have the 5.0L, 6.2L and 6.7L V8's, the 2.0L, 2.3L and 2.5L I4's, 2.7L and 3.5L V6's. All have 100 mm bore spacing. They differ in stroke / deck height and cylinder count variations that result in these different displacements.
Common design architecture and clearances = common issues.
