Niece drove her first car with no oil ! = clanking...

I know this is mostly a Ranger-only forum but knowledgeable folks here might know
my niece just got her license and a 2007 nissan murano SUV w about 111K miles.*
She knows nothing about cars yet.
It has a computer/screen that said to change the oil for some time and she didn't. The Low-Oil light on dash came on about a week ago so I think she either didn't know what it meant or thought it just meant to get an oil change.*

It was clanking for a couple days. Yesterday it got so bad that they told me about it and I told her to not drive it and I went to check it out.
It had no oil!
I put 4 quarts of 10w-30 just to get a decent reading on the dipstick, luckily it wasn't clanking after 4 quarts, luckily it didn't seize!
Then, right away I brought it to valvoline for an oil change and filter. It seems to run fine now.*

It had codes*
P0021 a camshaft position timing over-advanced or system performance Bank 2
P0011 same as above Bank 1
P0174 System too lean bank 2

She said she never saw oil drips where she parks and it doesn't smoke out the exhaust. Any idea why it lost all the oil?

For now I said just keep a close eye on dipstick level and carry around a large jug of 5W-30 in case it gets low.*

Also, any idea what this cut hose is? There's no slack to reattach and to see where it goes the whole engine has cover plates I didn't bother removing. Maybe I can just patch it to reattach. With engine running, if I put my finger over the nipple it attaches to, it sucks in.*

Why is it when someone posts about doing something stupid.....it's always about a friend or family member.

The engine is toast, just move on.

Try clearing codes, Camshaft Position sensor may been on due to low oil pressure and the engine trying to compensate, if it comes back after driving for 5-7 miles, it may need to be swapped.

Other sensors could be because engine was low on oil also, engine heat without ability for oil to cool it down.

Check the coolant for oil, and its not leaking when she parks, its definitely coming out the exhaust. It may smoke very slightly and it may not be under acceleration.. Under acceleration is only indication of the Rings being bad. Upon deceleration, now there's an issue with the valve stem seals and not always when someones paying real attention tot he exhaust.

Clearly a vacuum leak, should be able to reconnect it to the nipple off the I/M (Intake Manifold) if the hose is bound up or shorter than necessary, you will have to cut a 1/2" off take it to your local parts store and ask for a foot or two of that hose size [give them the sample] and chase the other side. If that's beyond tooling or abilities, just get a foot of hose, a same size male interconnect [see link example] cut back the older line a little farther back and just connect the lines as needed and cut down the new line so you don't have an over extended line laying there.
