Removed and replaced with 6.2 due in part to mistaken fault diagnosis.
Engine was running strong with 220k miles just prior to removal. I mistook loss of oil to be failed AFM and bought a replacement engine to swap in to minimize downtime. Issue turned out to be completely clogged exhaust due to catalytic converters blocking and collapsing. Didn't figure that out until the new engine was in and had problems.
Problem was that with nowhere to go exhaust pressurised the block and pushed oil into intake which exacerbated the problem by further messing up cats.
