My ht20 power steering has begun to pull to the left after the hydro fluid gets to a running temp, I have not checked it for what temp it is running out, though I don't feel it is getting to hot. Also the breather hole on the valve body of the cylinder has been weeping a bit of fluid for a little while. Any suggestions?
My fluid is fresh and clean, at a good level, good quality wix filter...
Thanks. Aaron

O rings in the valve body are worn and letting hydro fluid push past and thus the pull,its trying to activate sensing flow .The weeping out the vent is by product of the blow by. If it was mine it'd go down for a rebuild.. or possibly debris lodged in valve body (skeptical) .My experience based on age of the unit is most likely the o rings. Does the drag link stroke/move the spool ? The spools are notorious for seizing up.

It seems to me from the way it is acting it is infact yes the o rings. It pulls harder once at running temp, and it also seems to look up a but when turning right. I have never don't much to hydraulic systems, is there a specific o ring type I should be looking for?

Interesting topic, I would image that it is not too hard to rebuild the cylinder?
