Clutch reservoir options

[SantaFe66]

I had the same problem with Wilwood reservoirs. I called the tech line and they suggested replacing the o'ring and heating up the top before putting it on. He also suggested that I not tighten the wire clamp too tight and make sure the wires straddle the o'ring. Seems it deforms the joint when you over tighten it and then it leaks. Just a gentle tighten and it hasn't leaked since.

Good luck.

Mine also had mold lines in the plastic that I sanded off. Then I tightnened the clamp with a "big" screwdriver. We'll see if it starts leaking again when I can heat the engine compartment up. Has Olthoff released the aluminum reserviors yet?

Hope that is a little help from over here on the other side of the pond.
