Default Leaking oil.... Need help

Anyone know what line this is? It wraps around the front of the oil pan. It's got a ripped line. Spewing oil all over the place. Here's a photo

IT IS the PS high pressure line, be sure to use ATF fluid not PS fluid.... check your manual

I fixed 3 leaks on my LS.

One delete the air control valve that connects with the intake system.

Two of the leaks were coming from the valve cover's 10mm bolts, they get loose over time. Find an hour or so and torque those down.

Pr steering hose for sure. They are common leakers. I got mine on eBay for $40 but it's a tough job getting to the banjo fittings to replace it. I put off changing the valve cover gaskets and this hose for years. Finally did both and was thrilled with my clean garage floor for 6 months then traded for my LS 460 after owning the 91 for 15 years.

Torquing the valve covers didn't fix my valve cover leaks. I postponed it until the timing belt is due

The PS leak was a matter of replacing the o-ring on the pump connection going to the reservoir, new crush washer on the high pressure hose going to the pump, along with new shorty low pressure hoses at the reservoir since they were so hard they wouldn't seal correctly.

In fact the PS leak at the pump was so severe it looked like EVERYTHING was leaking all the way down to the steering rack.

Grab a few cans of brake cleaner and blast as much gunk away as you can, then monitor for new seepage before you go replacing stuff.
