i jsut got a new steering pump from ebay. my old one was going WHAAAAAAAAA...... WHAAAAAAAAAAA.... so it was dead. i put the new one on and started the car and theres no more WAAAAAAAAA but theres also no power steering. so what happened. all the fluid that drainded out the bottom of the car i cought in a bowl and dumped back in the resovoire so theres fluid in it.... i looked down to make sure it saw spinning and it is. what else could i have done wrong. could one of the banjo bolts be in wrong. im pretty sure i put them in the same way they came out. or could it be something like the fluid jsut hasnt gotten down to the pump yet. i drove around the block. but it still is the same.

by the way this post if from me, ian was just logged in on my computer and i didnt realise.

is there any "foam" in the fluid tank? if so it could mean a leak on the pick up line running from the tank to the pump. Mine had a "hole" in it right below the tank and I kept getting foam and AHHHHH sound from the pump. Reached down to check it and it pulled apart in my hand. Good think I had picked up an updated shorter hose a few months before, just never got arond to slaping it on untill that happened.

If theres no foam in the tank don't spend to much time on the hose thing because chances are thats not your problem.

no theres not any foam. its almost like it isnt pumping anything. could the pump be clogged. i saw a small peice of some black filmy gumk down in one of the banjo bolt holes. but when i spun the pump in my hand stuff still oozed out.

try bleeding the air out of the P/S system. with the engine running, slowly turn the wheel several times lock-lock.

also check to make sure that the fluid level in the reservoir is not raising by more than 10mm or so when you start the car. if the fluid level increases by more than 10mm, then you got too much air in the system.

also get some new fluid, this is a Porsche and the fluid is cheap. go down to your local auto parts shop and get a $3 worth of Dexron II ATF fluid.

does anyone knwo what hose is the return hose. if i disconnect the return hose and put a oil pan under the car then have someone start it up. fluid should start pumping out the hole..... right. then i would be able to make sure its pumping anything. would that work. is it even practical?

Cass944

ok yeah ill do that first. tomarrow. i have to go all the way down to vernon hills to the foreign currency exchange. i have a crap load of euro my dad gave me because he thought he couldnt get it exchanged. hehehe.... im sneaky. its about 80$ too.

hum, are you sure the pump was new?, good?.

questionable steering rack?

I would first start checking the easy, cheap, but unlikely parts. take the holes off one by one and more sure their isn't a clot in one of hoses.

take the pump out and attach one of hoses to it, to act like a reservoir for fluid. try turning the pulley by hand and see if the pump, pumps fluid.

replace the reservoir, bcs there is an un-replaceable filter in the bottom of it.

DO Not run the car with no P/S fluid. you can damage the pump by doing that. you don't have remove the pump to test it, just take the pulley off.

if you do take the Banjo Bolts out make your life easier by marking on the head of the bolt with white out, the holes in the bolt. that way, you are sure the holes in the bolt line up with the hose. if you need some new bolts, check with a VW / audi parts place, bcs they are much cheaper there.

i was thinking the reservior too...being that im holding mine in my hand right now.....possible the filter is clogged and no/little fluid is actually making it to the pump. i got mine from 944online...was 25 bucks or so

They have 4 holes in place of the standard 2 and they also have a hex head so you dont have to fiddle with those allen head ones. They are only for replaceing the 2 on the rack that hold the lines going to and from the pump. They come with new washers also.

as far as it being the rack itself, its highly unlikely unless you have tons of fluid building up in the boots. I did have a situation once where someones pressure relief springs inside the rack had broken. It was letting the fluid run back to the pump without going to the steering part of the rack. This is also unlikely because you would not get the groan from the pump if this happened, only loss of assist. Usualy the lack of assist when this happens is only in one directions because only one pressure relief spring breaks.

If you fix your groan, find you have fluid moving, and still have no power you might want to check the springs. If it comes to that email me and I will walk you through it. you dont have to pull the rack to check them if you do it right.

wait the holes int he najo bolts have to line up with the tube? i didnt know thta i thought it didnt matter bcause of the shape of the inside of the ring part of the tube. does the hole need to be facing the other hole? because i didnt even think about that.

Cass944

and all the situations you guys suggested, i dont think its anything but the pump or were the hoses connect to the pump. if i put my old pump on it works fine. i even have power steering. its jsut makes the groaning sound (quite loudly too) but then when i put the new pump on it doesnt make the osund but also doesnt make any power steering. i have not tried putting the old on back on yet. but im pretty sure its the pump or the hoses connecting to it.

even with air in the system you should still have some assist if the pump is pumping.

if your old one works and this one does not.... must be the pump.

there is not much to the whole power steering system on these cars. If it growns, theres air getting in somewhere. If there is no pressure, you have a bad pump. If it leaks out the boots of the rack you need new rack seals. Thats about all there is to it.

Sorry to chime in, but very interesting reading here!

I started leaking fluid in early January, and the car has been going through a quart of ATM fluid every two weeks.

When I hear the groaning and check the reservoir, there's tons of foam. Of course it only leaks at full opposite lock though... (You can tell becuase there are ATM Fluid stains all over the parking lot in corners where I have to turn the steering wheel all the way..)

We just jacked up the turbo to check exactly where it's leaking from, as I didn't want to get sflraver's rack seam kit if it was something else leaking.

Upon wiping everything clean, and turning the wheel lock to lock with the engine running, you can see red building up between the two halves of the PS pump. I don't know if there's a gasket in there, but we checked all the bolts, and the one mounting bolt up high in the back, was loose, but it seemed like it was actaully stripped. I don't know if that is just a mounting screw, or if it actually also screws shut the PS Pump shell.

I don't want to remove and replace the whole shabang if you guys say that a new reservoir and downpie might cure all...

advice?

please? <img border="0" title="" alt="[Frown]" src="frown.gif" />

I have heard of quite a few cases of pumps leaking from the parting lines. I have never had one apart myself (yet) but people have said there is a large rubber O-ring that runs the whole way around the pump where it comes together. Like I said, I have never had one apart so thats about all the help I can be. Good luck.
