On Monday I noticed a little puddle under the front of the car, PAS fluid

 

on inspection today I have found the crimp for the banjo fitting on the power steering pump to be leaking fluid, I think this issue to old age and nothing more

 

there is no way I would attempt a repair to this pipe, it’s 120 BAR in there, 1740 psi

a new RHD high pressure hose is $450

 

please inspect this pipe next time your under there

Great advice, this is a known weak pointy. The PS hose on the passenger side (LHD) seems to always be leaking.

Yup, mine blew in the driveway, the day after I brought the car up to Oregon, and emptied the power steering system of all of the hydraulic fluid. And the release also bathed the lower part of engine compartment in a hydraulic fluid aerosol. Had to power wash the underside with hot water and Dawn detergent.

lucky for you guys, the LHD version 944 347 447 03 is only 285 dollars, half the price of a RHD one

A small leak on my car started recently, as well.     Hey, old age and small leaks go hand in hand..and not just cars    :lol:

Shush, behave yourself

 

this was a bit more than a little leak, if I leaked that much it would be a bladder transplant, or a carefully inserted drain

A tip: go with your old hose to a hydraulic store. They will make a new one for you. Within 15 minutes you will have a new one. And for a fraction of the costs. For 50 bucks you are ready.

I have had a couple of quotes, Pirtek wanted at least £200 and needed to cut up the old one for parts

 

and that was the cheapest quote for a one off new one, think the price doubles when you mention Porsche,

 

anyway I found a company here called Power Steering Hoses, got a brand new one that was made for a 944 for £84 so that’s about $105

 

so I’m happy, just waiting for delivery

New line arrived, had to cut all the protective stuff off the old one and superglue it on to the new one, but there it is in the bag

 

so this is $100 worth

 



 



 

this is about twice the size of a LHD one as it goes across the car and back, I have the old one that i will take to my local store Pirtek, I'm sure they will want a small ransom.

Uhhggg.  PS.   First time I saw green on the shop floor I freaked.  I didn't know PS for Porsche was also green.  Thought it was coolant.

 

Then the saga began. A few revelations along the way. I had three problems uncovered now.

Whoever serviced the PS Pump last time didn't replace the crush washers around the high pressure side of the banjo bolt. None where found. That was #1.

When I took the PS pump off to redo the seals, I found that the double ended thread stud was sheared off internally 1/2 way in to the PS pump.  It just pulled out with half the thread length broken off. The fact that I was able to open the inside of the PS pump with only the 3 bolts meant it wasn't sealing on one of the corners. Had to reverse drill out the broken stud.  Eventually it dislodged and backed out without striping the female side of the thread in the PS pump.  The was #2.  Got it all back together and its still leaking.  Inspecting it further, looks like its dripped down from the feeding hose coming out of reserve tank.  Right where it takes a horizontal bend. Looking at Pelicon parts, looks like there is a change to the original hose and it has a rerouted design which is more direct and doesn't do the funny horizontal bend. That's #3.  Why Porsche, why? 

I hope that's will be the end of it.   Smartest thing I did was order a discounted 2 pack of the CF PS fluid. Have used it all up now.

Never seen anything but red PS fluid , on this side of the pond . Problem is that I also use orange coolant so at first look form a distance, a spot on the ground can be confusing ..

Should have bought a new fluid tank while you were in there, the tank has a filter in it that you can’t remove or clean, I would suggest after 30 years it’s a bit cruddy 

 

the tanks are less than $30 as they are the same on almost all late 80’s BMW’s

 

the hoses on the bottom of the tank leaking is almost a standard fitment

I'm on the same side of the pond. ;-)

 

What PS fluid are you using in the 968? 

 

 I believe it should be this:

Have not installed the hose yet. I'll add the tank per your recommendation.    My parts list keeps getting longer.

not an expression that I am used to over here.  I supposed it means, "its expected to leak?".   I love learning English expressions. I like throwing in "Obligatory" in my phrases just because it's fun saying and has people scratching their heads over here as to what I am saying.

..... I think the parts list is never ending! Though that's not a complaint, being retired and not having to rely on my 968 as a main ride means I can be relaxed about the fairly constant trickle of jobs; part of the challenge of owning collector's cars.  Were I a one-car youngster I'd probably get fairly tired of it all.  Then again, had I had a 968 in my teens/early twenties, I probably wouldn't be talking to you now.  I do regret not discovering club racing  :glare:  :glare:

Not sure what brand(s) I use, I’ll have to look in the garage to see what I currently have on the shelves, but I know it’s not that one.

Even though it’s always advisable to use what Porsche recommends, I believe any high end fluid should be fine , heck you can also use transmission fluid, in most cases it’s interchangeable with power steering fluid; both hydraulic both almost identical in composition and tolerances, but again, best to stick with PS branded fluid, maybe there are small differences that work best in that system.

The PS fluid should be Dexron II, I have to admit in my 40 years of spannering I have never seen green pas fluid?, but then every day is a school day!

 

Dexron II is still available all over the place, and you only need a litre,

 

without research I would not say that the fluid you quote in the link above would be suitable as it is a much higher spec than the old systems,

 

 

Quote

 

"Porsche says that the fluid to be used in the 928 automatic transmissions and power steering systems should be Dexron II(D). Dexron is not a brand, but instead a GM fluid specification and license. If you certified that your fluid met the Dexron II(D) spec and paid GM $3000 per year, you could label your fluid as Dexron II(D). The II(D) spec became obsolete, and was replaced by Dexron III, which went thru a series of minor spec changes, ending with III(H). Dexron III was specified to be backwards-compatible with II(D), but Porsche never changed their specification (or at least not by the 1993 date in my Workshop Manual).


Dexron III(H) is now obsolete, and all GM licenses for the product have expired. There are no fluids on the market that are certified/licensed as Dexron II or III. There are fluids that are recommended for use where the Dexron II or III fluids are specified, but they are not certified or licensed as Dexron.


GM has now introduced Dexron VI, which they say is a much-improved fluid, and is backwards-compatible with Dexron II and Dexron III. The specs are much tougher to meet, and any fluid licensed as Dexron VI should fully meet all of GM's new specs. No pure dino base oil will meet the new specs, so all Dexron VI is at least a Synthetic Oil"

Seems previous owner was using the wrong fluid. As 968 uses a 944 pump Im going to assume it should be dextron instead of the green stuff
