Ok here goes. My guess is the belts she put on were not quite tensioned enough and they popped off based on the rub marks on the pulley shaft closer to the engine.
Then it clearly overheated and I'm guessing that is the left side head gasket that blew the oil out of it?
Hopefully we have a DD mechanic or knowledgeable folks in here. Her goal is to try and get it towed tomorrow am, but knowing what the damage is, the likely cause, and the likely fix would sure help.
Engine bay before issue.
Left side oil leaking - went from 1/2 full on the dipstick to just on the add line so not a ton of oil lost but definitely not a good thing.
The pulleys that caused the overheat once the belts were gone.
And the stupidest place for gauges ever. What kind of setup is this that you have to wait for a warning light on the dash, pull over and shut down, then go run back to the bus to see what the issue is.
Hoping for any knowledge to help get this healthy again. Thanks!!
