Next up, front brake cooling.

Thanks Bruce. Glad you're happy. I'll try to find some modeling styrofoam tomorrow for the brake ducts. I know what is needed, but making them is a different story. BUT, I have some VERY skilled friends.........

yeah, I had ambitious plans of doing a catch can and brake ducts this weekend. The sunny weather lured me to the hills. Ended up putting a hose on the car and calling it a day. There's always next weekend.

My nalgene bottle did the trick this weekend too. It caught about 1/4 cup of fluid. Normally, I'm pround of my 'workman' solutions and share the pics, but this one looks so bad I'm actually too embarrased to show it. 
Especially after Enthuz's nice looking piece.

I found some leaking on the diff (passenger side right above the drive shaft), does your diff. also leak on the passenger side? I plan to fix it with hose. Does any one has pix?
Well, I plan to start tracking my Z in couple months! Just for street driving, I couldn't believe the diff. already start leaking !

I'm going to try and adjust the clutch engagement point this weekend. I'm still nursing the last of my oem rotors/pads before I swap in the carbotech/centric stuff for VIR in 5 weeks. I plan on jacking up the car this weekend and taking a look at the diff for any leakage.
I'm running BG fluids in my trans and diff.

Guys, if your lsd is leaking due to overheating, it will come out of the overflow tube and be dumped into the chassis on the drivers side. You will see crusty oil flowing down in the area of the rear spring. If you are seeing oil on the pumpking itself, you have bad seals not an overflowing diff.
The side seals should be changed any time the flanges are removed. I learned this after taking my diff down a couple of times. Even thought the rubber is in good shape, there is a spring inside the rubber that is easly stretched out. The seal is $7 and is easily installed with the pumpkin on the car.

The best oil degreaser is Purple Power, spary on it and wash it off w/ water. You can get it from Walmart or Kragen! Make sure you wear eye protection, they are strong!

Well, you need to wash it off completely to pinpoint the leaking area. Same situation here, yesterday, I wash it off and test drove it for 1/2 hour, but I don't see any new leaking. I plan to drive it for couple more days and see what happen. I will keep you posting!

I did that, and it looks like its mainly on the driver's side coming from the top of the pumpkin. I didn't have a chance to get it on the lift, and after driving for a little while it started leaking. I'm definitely thinking its a seal, unless the diff is cracked or something but that seems unrealistic.
