PAS on 1990 16v intermittent

Recommended Posts

Last night my PAS decided to not work. I pulled the belt off the, and found the pulley that sits on the outside of the water pump a little stiff...

 

So this was removed, checked, reseated, seemed fine. Drove car to MOT fine, got nearly home, no PAS again *frown*

 

pump is making no noise, rack is not leaking, none of the pipes are leaking

 

was fine for 20 mins yesterday, then packed up, checked it over but couldnt see anything and checked all the pulleys. Then when going over a load of bumps it came back. Then died again as i was hooning up to a tight chicane *surprised*

 

I'm thinking maybe the valves in the rack are sticking?

 

Also the pas fluid looked suspiciously like ATF fluid which VW's do NOT like. Could this be an issue? I though that generally killed the pumps. A pump can't be intermittent, right? If it's turning, it's pumping unless its dead, but not gonna come and go?

 

Thanks for any help
