HOW TO DO AN ADVANCED SEARCH.
Mon Jul 08, 2013 3:56 pm by Admin
For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.
When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).
After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Wilwood clutch MC leaking at boot immediately after install/bleed
The wilwood clutch MC I installed (sideways, directly on firewall) started leaking immediately after the first time I installed and bled the system. Zero drive time. Does this indicate a faulty MC or did I do something wrong?
Using a speed bleeder from Tick Performance, Spec 1 clutch.
Many thanks for any advice/intel-

I did the same set up - widened the mount holes turned it sideways. I used a hand vacuum pump to bleed. The pedal hasn't been worked much, been sitting for a while now.

Did you remove and install the piston? If so, you may have torn the rubber seal on the piston (don't ask me how I know).

Nope. Did not take apart or modify . . .

Mine was leaking from the reservoir, I accidentally pinched the o-ring seal where it goes on the M/C, might want to check there unless its leaking from the pushrod side.

Pushrod side. It's not a lot, not even dripping, but I can see the wetness of the fluid. If I pump the pedal, more fluid . . . Can only assume it will get worse.
Can't figure out if i screwed it up somehow or if it's faulty.
Seems like failure caused by me would take longer to happen than just the bleeding procedure. Other than the pics that are already on the forum, does anyone have a pic of a successful mating of the wilwood MC to the Porsche pedal? other than a bad angle what else could cause such a leak at the back of the pushrod/boot?

Here is how mine looks, not a great pic though.
Its entirely possible it was just a bad master cylinder, which model are you using? Either the bore is scored or the piston seal is bad.
Can you confirm the angle of the push rod is correct? Push the pedal in by hand and look at the action of the push rod to see how well aligned it is.

Re: Wilwood clutch MC leaking at boot immediately after install/bleed
Thanks techno duck. I've learned a lot from your build.
Angle is very straight. Once I pulled back boot there was a lot of fluid that dumped out. Ugh. Two things I noticed:
Whitish kind of goo/dust around entrance of pushrod.
Pushrod seems to be a bit high in the bore- i.e. there is a larger gap between pushrod and bore at the bottom than at the top. Like a 1/32". Does that mean my angle is off? Would I correct that by shimming on firewall or in linkage? OR, I'm wondering if the hole i tapped isn't canted upwards a tiny bit and shoving the pushrod against the top of the bore. It so so minimal though for immediate failure-

Re: Wilwood clutch MC leaking at boot immediately after install/bleed
I the MC body sitting flush against the firewall? Have you checked the firewall for cracks? Maybe when you widened the mounting holes it made the body of the MC sit too low in the firewall hole making the pushrod sit too high. I have noticed my brake and clutch MCs have some fluid in the boots over time, very very little.
