Hello and need some help


911 Rod

Recommended Posts

Hello everyone,

I picked up a TT last week and it's as much fun as I thought it would be :thumbup:

Snow tires on it and this thing feels like it will go anywhere!

The problem I have is the front steering fluid tank is leaking through what appears to be a vent hole.

The rear tank does not show any fluid on the dipstick.

Is there a check valve gone bad somewhere? I can fill the tank, but I don't think that will fix it.

Thanks

Rod

The front reservoir is for the clutch and if it is overfilled it is due to a faulty clutch slave actuator.

The clutch system used the power steering system pressure to help you depress the clutch pedal. If the slave is faulty there is a migration of fluid between the steering and clutch system. If you look at the steering reservoir which is the engine compartment you will found the reservoir level low…. For now you can always remove this extra fluid and refill the steering reservoir. I did this for a couple of months before replacing the slave and accumulator at the same time

The slave part# is : 99611623752 and it is about $352.00 and the accumulator : 99731416600 $114.00 and it takes about 3 hours to replace those parts….

​Of course there is a third possibility to fix this problem forever: The GT2 system, many threads about this subject...

That makes sense. So when I push in the clutch it pushes the fluid forward or when I turn the steering?

I knew I had a problem when I heard strange noises when I turned the steering.

I guess I'll get my turkey baster out and start transfering fluid so I can drive it.

Is the GT2 system better?

Thanks for your help.

The noise is probably from the fact you had low level in the steering reservoir. The pressure being a lot higher coming from the steering pump , it migrate to the clutch system through a weak slave part. Some say a worn seal and some are talking about a weak check valve….. GT2 better??? Hum, I cannot answer, there are some pro and con out there ;-) I still got the slave on my car. But many post on the subject on Rennlist and 6speed: Happy reading!

Hi 911 Rod:

I agree with Jpflip on this. It is something pretty common with 996 turbos for the clutch slave to go bad. It happened to me on my old 996tt. It will be very clear to you if you look at the clutch reservior under the hood that is probably overfilled and leaking. The GT2 Slave solution is the best way to go. It will provide a slight increase in pedal pressure effort and it will cost a bit higher that just replacing the stock salve but gets rid of this problem that repeats quite often.

Best of luck!
