Crankshaft Pulley replacement help needed

2zz-ge engine, 2001 body.

I'm going to keep this short and save you all some second hand frustration. I picked up my car this weekend after 4 months of being repaired. New alternator, tensioner belt, PCV bleeder and some solenoid for VVTLI. After driving it for 1, one, hour at speeds between 55 to 75, I heard a loud clunk, looked in my rear view mirror to see if I ran over anything, and see the crankshaft pulley sailing away at ample speed. Took the next exit, looked at the engine, and yep its gone. Somehow the belt was intact too...Got a tow, and now car is at a friend's house.

My questions are:

1. Will this do any permanent damage to the engine?
2. Can I just get a new pulley and put it on there, route the belt and be fine?
3. Is there any way that I can see if the timing is incorrect without dropping the engine and removing the timing chain cover and looking at the teeth? Maybe through the OBD port?

I know a pulley tool can be rented from amazon and have all the manuals...just debating on calling an import/enthusiast shop in town and see what they charge because I live 40 minutes from where the car is located so I can't take other photos.

Open to suggestions/advice and thank you.

Hard to tell without a proper examination. Good thing you stopped at the earliest chance.
There is an oil leak from the picture. The timing chain cover may have to come out anyway. you mentioned to me that your mechanic was trying to fix an oil leak, did they by any chance remove the timing chain cover?
I was going 75 pulleys were recovered lol. The overflow tank cap did not pop out but the bottle was steaming a bit. The engine was run for less than 5 mins total after the pulley flew off. Temps never reached above 220 F from my readings with my code reader. (one was a few mins after the other so I guess it had cooled off 5 degrees from the first reading)
That’s good news. Five minutes is not going to damage your head gasket.
What I would do in your situation is inspect where are the oil leak is coming from and address it before putting on a new crank pulley. The next thing I would do is inspect the crank to make sure it’s not damaged in someway that would make the crank pulley come off again.
Paul and Carl knows a shop in the area that does very good work. I would trust that guys opinion.
