Figured I'd start a new thread...
Sharker mentioned videos but I did a quick you tube search with no success - anybody gots links?

Thanks!

Sharker

The post on how to do it is here https://rennlist.com/forums/964-foru...build-diy.html

Video is here.. they are referring to a 944 pump, but same thing

Are you sure its is the pump leaking?

mine was cam seal and ´´O ´´ ring for the power steering pump

you should be able to search either here or pelican 964 thread on changing these two parts.

Looks like another "while your in there" task for me while my engine's out...

If it is leaking at the cam seal, would that not be leaking engine oil?

I know mine is leaking PS fluid, as it is filled with Pentosin Chf11, and the drips are clear, and my reservoir is getting lower very slowly. Just want to make sure I am tackling the right problem

yeah mine's leaking engine oil, not PS fluid. Right onto the heat exchanger - and then while moving me thinks it sprays/flies onto the muffler. Stinky. Smoky. Not behavior worthy of a 911 Turbo.

You can change it with the engine in the car. Takes approximately 2 hours, 90% of it while laying on your back.
I did mine 3 years ago and I saw it was weeping a little when I took the pump assembly off the engine

I would love to just be able to see the little bugger, so I can see if it is leaking at the pump, or one of the hoses. These engineers figure all of the mechanics have arms like this

Metal Guru

Hey, man, lay off the engineers

2 hours you say? Not bad considering that's probably 4 for me :-)

Good to know - thanks!

Sharker

how long did it take you to get the pump off :P

Metal Guru

Being the clever engineer that I am, I left it on But yeah, removing it is one of those tasks that has you under and over the car.
If you think our pump location is bad, check out the water-cooled cars. You literally have to remove the rear end of the car to access it and then it's buried on the engine.

I heard from a knowledgeable source that the vast majority of the time the leak (oil not PS fluid) is at the seal not the O-ring - and the seal is easier (or should I say less difficult!) to get to.

Comments? Thoughts?

I talked to a known good shop here and it sounds like they bill 4-5 hours in labor to do the seal - another couple hours for the O-ring. I think I'll give er a shot.

Metal Guru

Well, the seal is in the housing and the o-ring is on the cam and will take you an extra 5 minutes to replace. When I did mine the o-ring was as hard as raw pasta so you might as well do both. Four-five hours is too much time for a shop to charge. It's a job you can do yourself.https://rennlist.com/forums/964-foru...seal-leak.html

Ok - yeah if its just a few more minutes definitely. They said another two hours! Figures.

I'm going to put this little project aside for a month or so as I need to change the oil and figure out why I have no washer fluid coming out anywhere. Taking the car on a road trip 4th of July week - Denver to Sioux Falls, SD.
