Is there a way to look inside of the Oil Pan? What was the condition of the Oil. Meaning does it smell burnt is there coolant in it and so on. Looking for something abnrmal.

No one mentioned if before it died there was smoke, steam, coolant smell, burnt oil smell and so on.

If you can see inside of the coolant recovery tank what does it look and smell like?

If coolant got into the cylinder it creates a hydraulic lock and the Engine won't turn but eventually the coolant passes through the piston ring gaps and into the Oil Pan.

I could have missed it but was there any odd noise before the failure.

Something happened to the timing Chain and or gears.
