1990 Celica 5S-FE
Today in the morning I decided to take my car upstate in the mountains for a touge since it was foggy/misty in the mountains. I noticed when I was pulling my car out my autoshop when I turned the steering wheel it seems the power steering made a squeaking hydraulic sound like something is compressing. Note that through the entire ride to and from the car never lost power steering though or had difficulty with steering. So I ignored the squeaking drove the car 100 miles on the highway and up through the mountain and stopped on the viewpoint. Car was running good as ever no issues. Drove back to the shop and when I turned the engine off opened the hood to connect the battery charger I heard this sound from what was EITHER the upper radiator hose or side of the engine block it sounded like gurgling, like you were quickly emptying a huge canister of water or oil. Then I noticed some smoking, looked over and saw what appeared to be oil ALL over the place in the engine bay and I mean EVERYWHERE. was on the back side of the engine all over the piping, transmission, firewall, suspension and covering everything in its path. Checked oil level and it was fine but the liquid was brown. What could this be? It looks almost as if the motor blew up but ran fine. Can’t detect any leaks. Please help.
Checked oil level and it was fine
check ALL the fluids.
transmission, power steering, brake, coolant, ....
That's what rusty coolant looks like in an old engine especially if maintenance has been neglected during it's life. Check everything as @imperator says but it sounds like you may have lost a core plug to corrosion, a common problem with decades-old engines.
This engine has 0 corrosion. Garage kept for all its life 74,000 miles and coolant is green like grass.

how do you know ? Did you look inside with a camera?
Garage kept for all its life 74,000 miles and coolant is green like
a garage has zero effect on your cooling system. Green coolant is only good for about 3 years.
