However, this compound has been replaced by Pentosin CHF202, and that was the one I ordered.

Suggestion
I would check all the reservoirs, clean the leak and leave it spotless.

I would also check with the dealer to confirm the replacement grade and that they are compatible ( can be mixed).
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi guys, I'm about to do some needed maintenance on my car, Upon inspection I noticed what seems to be oil/grease at the drivers front suspension.... seems to be originating around or above the lower suspension link/dog bone just behind the brake scoop. Any ideas? Is it grease from the suspension link boot?
Does it warrant replacement?
Any input is much appreciated.
As a side note, the LN IMS solution was done recently and AOS, I'm flushing the brakes, coolant and installing a new water pump and possibly a new low temp thermostat.
Thanks
Shalil
997.1s, leaking a few drops every night, very slow, brown-oily texture, few inches to the side of the right (passenger) rear wheel.
I snapped few pictures from below the car, without raising it (attached, all pictures looking from ground up).
I added engine oil (one quart). The level of the power steering fluid is low, I have not added Pentosin yet.
Any idea where that leak could have originated from? Where next should I look before taking it to my preferred workshop?
Thanks in advance
Assuming the coolant in your car is yellow (and not pink/orange), it looks like coolant to me... and it looks like it's coming from above where you're looking. You can see it pooling up on the coolant hard line in the top of the first pic.
Oil would be much darker. I haven't had a Pentosin hydraulic fluid leak since my old Audi 5000, so I can't remember what that looks like.
I'd see if you can view anything from the top looking down.

Marco,
Thank you for looking and taking the time to answer!
Quick questions: assuming it is leaking coolant... do you expect the leaked liquid to have some oily property when touched (very liquid, but slippery) ?
I will check the color of the coolant. I thought the coolant was topped off: could it be that it was overfilled, and on a very hot day like yesterday, it expanded and burst a joint/pipe ?
. Coolant level a tiny bit below the minimum level
. Power Steering fluid not detected using the 20second routine described in the workshop manuals.
No symptoms, no warning lights.
It could be either/or at this stage. Any idea how I can differentiate between the Pentosin and the coolant liquid, other than "tasting" it and poisoning myself ?
If the masses are saying Penotin/PS Fluid, I'd go with that, especially if it isn't detecting the level. I would have assumed the 997 would have the better "Pink" coolant, but I've never looked. Both fluid can be slimy, but PS fluid more so than coolant.
Assuming it is PS fluid, start at the pump and work your way out from there. It's clearly originating in the engine bay, so I wouldn't worry about the steering rack up front. Check the lines coming off the pump first and follow the wetness to the highest/originating point.
What color is your coolant? If it is pink then you can rule that out. Coolant also has quite a distinct smell. Looks very much like old Pentosin to me. The PS pump is on the top of the motor just slightly off center to the passenger side. Should be easy to see if there are leaks around it.
I checked the Pentosin pump: no visible leaks around the pump or the pump cover. Looking down, it was difficult to see: very crowded real estate there!
On a white paper towel, the liquid appeared almost transparent, i couldnot spot any coloring. I scotched under the car a matrix of white papers (printer paper) to pin point the leak, and report on the color.
That said, looking from under the car upward, there are traces of black greasy residue on some parts, feels like grease that has been there for a century or more...
I do appreciate all the feedback so far, you guys rock, and this forum is wonderful!
Coolant will smell sweet. Oil smells like,well, oil. Transaxle very strong smelling oil, Most other fluids (power steering, power top hydraulics etc smell somewhat like auto transmission fluid. So... what does it smell like?
id never pressure wash, do it all by hand, damp cloth with a touch of simple green on it. looks like power steering fluid to me. Id clean it up and have you fav shop take a peak and chase it down after a few hundred miles of cleaning it up.
I scotch-taped white printer paper under the car, and left it overnight. In the morning, on the paper, a single drop about one inch diameter, oily, no color tint at all.
With the iPhone camera pointing upward, flash on, I snapped a picture (see below). Then I touched the accumulated green drops:
. very smooth, with the viscosity of water
. leaves on the skin a very mild oily sensation
. No color tint when on the skin
. No smell at all
Felt like a diluted mix of oil. I will wash this area as suggested this afternoon, then fill Pentosin tomorrow afternoon, and drive it a couple of miles, per the suggestion above.
I'd say it is a safe bet that it is Pentosin. It only takes a connector to be very slightly loose on the high pressure side to have a leak. Carry some Pentosin in the vehicle until you resolve this.
If it is power steering fluid just be sure you get the right one to top it off. Pentosin is simply a brand name and some of their power steering fluids are mineral based and some are synthetic based.

Thanks ! I hope that I ordered the right one: the cover of the reservoir says Pentosin CH11s. However, this compound has been replaced by Pentosin CHF202, and that was the one I ordered. Right ?
I bought a can of Pentosin CHF202. The texture of the fluid is exactly the same as the leak, confirming that the leak is Pentosin. You were all right!
I filled the reservoir appropriately. It needed very little, less than an italian espresso coffee.
Next: take it to my favorite indy shop or dealer to repair the leak. Thanks all for your help!
The leak was an O-ring poorly adjusted!! Jared at ForeignAffairs motorsports took care, labor charges only. Now testing it for a week, and monitoring fluids and garage floor... Thanks all for your help!!!
O-Ring. Yep. I was doing a search and found this thread. I went for a spirited drive today and parked the car. When I came back out the car had puked all of the pentosin onto the ground. Crazy. 2nd time it's done this in my manual 997 Turbo. It was an o-ring last time. It's so empty that I barely got home with the clutch barely working. If I fill it up with Pentosin can I drive it to my shop for repair or should I flat bed it? Just goes into the resivour for power steering under the bonnet right? Could I be riding the clutch too much causing this to occur twice now??
