The point I'm trying to make about the o rings is that if the pan were disturbed it would be prudent & ridiculously easy to replace them. They are not caught early enough on post 2000s until damage is done because of the lack of tappet noise when oil pressure is low (due to the non hydraulic design after 1999)
I agree with the rod bearings (and possibly main bearings as well) being part of the problem here but I would want to eliminate a $20 set of seals first before embarking on such a large repair. You don't just slide new rod bearings in even if it looks easy enough. You would want to take plastic guage measurements on all the conrod to crank clearances. In any case once the sump is re-opened all these items can be rechecked easily enough.
Just reading back, the only thing he doesn't mention is o-rings replacement. Was it done or not? PCV system oil drains were clear?
He says about checking the bearings, but there were metal fillings he found in the drained oil. It's not normal on any engine at this mileage, so were from?
