Checked the blow-by with the filler cap off when assessing for any damage from the oil cooler line failure. Also pressure checked cooling system.

The engine never overheated, and still had a minimum of oil pressure when it shut down.

The engine only has 143K on it and was running like a Swiss watch when the line blew so I doubt if the filters are plugged.

Is there a transfer pump in the IP that draws the fuel from the tank first?

Just trying to connect why I would loose throttle response in coordination with oil line failure.
