Question: Other than the O-ring on the fitting that goes into the rack (that can be seen in the pic), is there another O-ring inside the assembly that allows the metal tube to swivel in the fitting? If there is, the heat from the welding may destroy that o-ring. I would then have to go another route and avoid welding. Also need to think of the heat will destroy the one-way valve on the HP side fitting...
Need to know if there is an o-ring inside the fittings at the place marked by arrows. Appreciate if anyone knows...  |
PorscheFan,
No, there are not any O-rings where your arrows are pointing, actually the thin aluminum tubes are press fitted into the connector and this is a weak point…
On my car, this is the place were started leaking, and what I ended doing, was to weld (ok, took it to someone that knew how..) an AN fitting directly to the coupling that attaches into the rack.
Basically the same idea you have but eliminating the thin 90 degree aluminum tube and used new O-rings on the fitting that goes into the rack.
On my car, I used the return (low pressure side) of the rack to connect an Setrag (..?) oil cooler and after 4 or 5 years I have not got any more leaks or fried PS pumps…
Good luck!
However some pics will help before I tear apart the rack end fittings...
