Does anyone know if I can put a can of this stop leak stuff in the power steering pump to stop a leak from that and in the rack? I know I need to replace both but this may buy me some time unless it could damage more then it helps. Thanks so much for any help- 92-968 coupe manual

that will probably screw up the pump.

I don't think it will work. Most of the leaks on both are from seals. If you don't mind the manual operation of the steering you can remove the belt from the pump and use it without the power assistance until you are able to fix it. From a dead stop is kind of heavy but after it is moving isn't too bad. I have this setup on my race car and it work just fine.

A can of Stop-Leak cost me $7,000+ on my last P-car, and led to my selling it in dejection and being P-carless for a decade.



And yes, P-carless is a word.

Emptied the reservoir and dumped in most of a bottle of P/S stop leak. Saved the last little bit for later as the rack was leaking around seal on left side. The leak stopped immediately and the remaining oil is still sitting on the work bench. That was a year ago. Should help with pump seals also. Have used seal softeners over the years for auto and aircraft with good results. Many acft gear struts get a good dose of seal softener in the hydraulic fluid before the strut is inflated.

If your pump is leaking, first try re-sealing it. It's not hard at all, parts are cheap and there's even a video available on you-tube that walks you through it. After I did mine, I found that a common leak area is where the ends of the pressure hose bolt up to the pump and the rack. Make sure you use new washers in those areas - used ones tend not to seal. They're available from Sunset Porsche.

Why not buy a second hand 944 manual rack and associated parts and do away with power steering, delrin clamp bushes a la Flash as well!

I second bombfactory's suggestion. I recently resealed my pump and didn't even manage to screw it up. I think the reseal kit was $20 from Paragon and the youtube video can be found here:http://www.youtube.com/watch?v=PsZOhqSfy-Y

Next job is the steering rack. I'm sure I'll manage to screw that up <img src="/forum/images/smilies/968/rock.gif" class="smilie" alt="" /> .

I'm way too chicken to attempt the rack, so I got a rebuilt one from AutoZone. So far so good, no leaks.

The rack is quite a bit more work than the pump, so be prepared. It really helps to have a very large vise (which I don't - had to use a neighbor's), because the rack is a very awkward piece, and you need to hold it securely when loosening the nuts that secure the half shafts. Also, be aware that there are A LOT of small parts buried in the thing, and you have to tug very hard on the some of the pieces to pull them out of the rack so you can get to the seals. While doing that, I had a number of joyous occasions when small parts came flying out of the rack when the part finally gave way. Definitely a few heart-stopping moments. Also, some of the seals on mine were stuck incredibly tight - it really took the right tool to get some of them out. If mine doesn't leak like a sieve when I finally fire the car up, it will be the biggest miracle since the '69 Mets.



But other people have had better luck, so maybe your experience will be better than mine. Good luck, and allow yourself a lot of time if you choose to take this on.

Nosferatu,



Out of curiosity, why did you remove the power steering pump belt from your race car? If you wanted manual operation (for better steering feel?), why didn't you pull off the pump, power steering cooler, etc., and plug the lines' fitting openings on the rack? Seems like this would save you close to ten pounds.



I've removed a good 90+ pounds from the front of my car, so I might be a good candidate for manual operation (particularly if, as I fear, my rack is going to leak after the very difficult re-seal job I did), so I'm curious as to why you went with manual operation on yours, and why you went the route you did. Thanks.

Sorry about that, we're talking about the PUMP, NOT THE RACK. Okay its in there now, yes a seal kit for the PUMP should be a piece of piss to install. Whereas the RACK re-furb kit is allegedly a pig as the seals down inside the rack are hard to extract and scoring the piston bore is possible...seemingly.

tamabumper, what caused the $7000. worth of damage after stop leak in power steering pump?

Not in PS pump, but in coolant, which shook my faith in any sort of stop-leak or stop-gap solution.

Man oh Man I am so dissappointed! My beautiful 968 that sat in a barn for years but was the fastest Porsche I ever drove, I mean fun, I mean this baby was like a grey hound! Now it is like a slow bullDOG <img src="/forum/images/smilies/968/whine.gif" class="smilie" alt="" /> I had the power steering pump, fuel pump, steering rack and A/C fixed this week and I had no idea at all this would totally ruin my pick-up and fun of driving my car. Any one have this experience with their car? Most important is there any way to reclaim the hp and fast pick up it had? Do I need to take all the new stuff out and put all the broken things back in <img src="/forum/images/smilies/968/glare.gif" class="smilie" alt="" /> WHAT a bummer

The only two things you mentioned that would draw HP away would be the power steering pump and the AC. While I notice a very slight drag with the AC on, I can't say it "ruins" the car, so I wonder if your fix involved putting in a rebuilt compressor that's presenting an excessive load due to some kind of failure?

I called the shop today and he said he can do an evaluation which involves alot of meters and such will take about 2 hours. Other then that he doesn't think any of the work he did caused my loss of power. I still have plenty of mid range hp but with the take off it's dead <img src="/forum/images/smilies/968/beer.gif" class="smilie" alt="" /> Big change from before work even passengers notice it. The guy did not replace compressor only clean system and changed to new cooler stuff no freon

My guess would that they knocked something loose while they were in there. Apart from the AC, none of those things should cause horsepower loss.
