Hello everyone, I am searching for a part for my 996 Turbo. I am leaking oil from the Turbo Scavenger Pump cover (#9961071421R). I need to replace it, but am being told by Porsche I cannot buy just the cover. They want me to buy the entire pump assembly (#9961061914R). $$$$$$$$$$

Does anyone have a used pump or cover? Or know where I might find one?

Thanks for your help.

cant you just re-seal it?

Bobw56

I do not think so. The seal relies on an O ring fitting over a circular part of the pump cover. The metal around the O ring is damaged and the O ring itself looks bad (probably why it leaked). I would hate to put a new O ring in with what appears to be a damaged base/cover.

I tried to attach pictures to show the issue.

Cannot see my pictures, so I guess I do not know how to do that.

Try posting them on flicker or something. You might be able to get a good machine shop repair it.

Can not say for certain without seeing condition of the o-ring groover and where it is in the pump, but if o-ring groove not too bad a new o-ring could have the unit oil tight again.

You can clean the o-ring with a fine and small file or diamond abrasive file-like thingie and smooth/polish the groove to remove any burrs/rough/sharp edges.

As long as the groove is complete so the o-ring can't get pulled out or pushed out by pressure it may seal just fine.

Might be worth a try. The scavenge pump shouldn't generate too much pressure even if that o-ring is on the pressure side of the pump.

Sincerely,

Macster.

Ok, thanks for all the replies and the great directions on how to load pictures. hopefully you can see the issue I have with the pump cover. A new O ring might reseal, but it does not look good to me. Any other opitions.

Macster

Forget it. You ain't going to polish that out.. What the heck happened?

In another life that could be welded up and remachined but that was another life.

Time for a new cover and if the cover not sold separately time for whatever that bolts to, is my WAG.

Sincerely,

Macster.

isnt the scavenge pump the same on the gt3 engine?..... maybe you can go that route and post a wtb in the wtb/gt3 section.... I assume you tried pelican.

Bobw56

Thanks for the second opinion. I agree and am not sure what made that cover disintegrate like that. The bottom line is I need a different cover and was hoping someone may have one laying around they needed to get rid of.

WHat price did they give you for the new scavenge pump? Also, how hard was it to remove that? Is this the pump right by the crank pulley? I looked at mine the other day as i have a leak from a similar area and I can't see how you would get access without removing the whole motor. The exhaust can drop, but then there is a that metal frame around everything back there. It looks like it goes to the motor mounts at the top??
