X-plug and PS pump questions
As far as I know under X plug there is a small
piston which will wear with age and start to
leak as under it there is high pressure and then
changing Xplug o-ring stop leakage for some time but
sooner or later you'll have X-plug leaking again.
True?
PS pump used in UrS cars has two sections, one
for brakes, one for PS.
True?
If twice true then which section of the pump
does X-plug belong to?

No (Maybe), Yes, and you should be able to figure it out. (See inside)
You said: (My comments are in CAPS - but I am not yelling):

True? COULD BE TRUE. THE X-PLUG O-RING SEEMS TO DETERIORATE OVER TIME. EXTRA PRESSURE FROM BLOWBY AROUND A PUMP PISTON COULD MAKE IT LEAK WORSE OR SOONER.
PS pump used in UrS cars has two sections, one
for brakes, one for PS.
True?YES.
If twice true then which section of the pump
does X-plug belong to?
FIRST OF ALL, THERE ARE MORE THAN ONE X-PLUG ON THE PUMP. THE ONE WE TYPICALLY HAVE PROBLEMS IS THE ONE ON THE TOP. YOU SHOULD BE ABLE TO FIGURE OUT WHICH X-PLUG (LOCATION WHERE THE PISTON IS LOADED INTO THE PUMP DURING MANUFACTURE (AND REBUILDING) IS LOCATED BY FOLLOWING THE APPROPRIATE PS AND BRAKE BOOSTER HOSES BACK TO THE PUMP.
PERSONALLY, I WOULD THINK YOU SHOULD BE LOOKING FOR A NEW OR REBUILT PUMP IF YOU ARE HAVING THAT MANY PROBLEMS.

the only problem is leak - PS is fine as well as braking
but someone told me that changing x-plug with its
oring is just short time cure due to that piston
wear and excessive pressure under the plug
soon I may be forced to take out generator
so rebuilding/exchanging PS pump at the same
would be easier task but for sure is a lot more
expensive and time consuming than just replacing
oring - hence my questions
I'll have PS pump which have PS section in a
very good condition so I'll try eventually
to rebiuld this one and then swap
thx

You have to make sure you get the right O-ring. Order the O-ring and X-plug together (see inside)
