In theory you could epoxy the base of the old leaker. Why Porsche did not use a one piece blow molded part like other manufacturers do ,I have no idea. It would have been a cheaper part too !

sounds like you are saying it leaks at the seam at the base.

I would like to test it, but the old one is still in there. I was not about to R&R the alternator to fit the new vacuum reservoir in. I was trying to meet a CA smog deadline and I knew I had good vacuum now.


So I left it in place and installed the new one temporarily over near the SAI air pump. I will take the old one out when/if i have to change the alternator.
