I have a 1994 Chevy Corsica with a 6 cylinder engine. The high pressure
power steering hose sprang a leak and was shooting fluid out. I doscovered
that it was a pinhole so I placed a piece of thick rubber over the pinhole
and put a hose clamp over the rubber to hold it tight against the hose in
order that I could drive it into town and get a mechanic to replace the
hose. When I started the car I found that another pinhole leak had started
and was spraying fluid out.
My question is- is something clogged up in the power steering system that is
putting too much pressure onto the hose and causing it to spring leaks, or
is the hose so old that it is just a coincidence that the second pinhole
leak occurred immediately after I patched the first hole? Does the power
steering system have a very high pressure? Is it possible that if I patch
the second pinhole leak that the system may become so pressurized from a
blockage that it will blow something out?

The hose would probably just leak from some other place. Have you been
using power steering fluid, or ATF, in this car?

This is a very high pressure system. If a hose is bad, it is likely bad
in a lot of different places. And most likely if ONE hose is bad, other
hoses are about to fail soon too.

The pressure in my Mercedes is 65 BAR which is about 975 PSI. Other models
are 85 BAR 1275 PSI.
Hoses fail. If all else is ok, there is nothing else wrong.
I like using Vavloline synthetic blend power steering fluid. It has
eliminated noise in several of my GM cars power steering systems. Pump out
what you can in the reservoir. Fill with fluid. Run it for a week or so.
Repeat several times until the fluid stays clean.
