the 3.5 has an 'internal' water pump. It is driven by the timing chain and is under the timing cover. when that leaks, it leaks into the engine oil system directly. it obviously doesn't take much to ruin the lube oil properties with water and glycol mix.
from here the oil pump picks up the contaminated lube oil and pumps through the engine...crankshaft mains, connecting rods, and cam shaft journals are all almost equally and identically affected. The check engine code can come from misfires or an out of sequence cam timing. This is due to the cam shaft phasers not working properly due to loss of oil pressure (because the engine bearings are coming apart).
I hope this helps clarify the technical basis.
This sucks big time for the OP. this is a very rare failure. Being a former dealership tech myself, I am super shocked they aren't working with you on this. I mean c'mon here they can't pay for at least a portion of this?
lesson learned for me: WATCH THAT COOLANT COOLANT LEVEL!
I'm spoiled to driving ford modular V-8s. The external water pump is a 30 minute job and easy to see a leak on.
Best piece of useful information for us owners, need to keep an eye on reservoir coolant looses...
