Title: vac pump base seal?
Post by: truckinwagen on February 17, 2010, 04:54:26 pm: is there a gasket or an oring that is supposed to be on the base of the vac pump?

I never noticed if there was, and I think I am leaking oil from where the vac pump goes into the block.

anyone know?

thanks,

I wouldn't think so but I've never held the diaphragm style one in my hands.

Mine is an 85, and has the newer style pump...

Post by: burn_your_money on February 18, 2010, 07:58:05 am: I think you have to check to make sure that it is still engaging in the oil pump shaft. I think I read that there are different heights.

That's good to know about the one in the bottom.

im pretty sure i dropped a gasser dizzy in a diesel block before. 99% for sure they are the same. the 2.0s have a bigger hole in the block tho.

Post by: burn_your_money on February 18, 2010, 11:17:57 am: Yeah the 2.0 should match the AAZ vac pump

Post by: fatmobile on February 18, 2010, 11:59:00 pm: Here's the seal Andrew is talking about:
(http://img291.imageshack.us/img291/1323/vpumpsealig4.jpg) (http://img291.imageshack.us/i/vpumpsealig4.jpg/)
It's usually a hard old black piece that looks like part of the pump. Keeps oil pressure frrom bleeding off.
Not sure where the best place to buy them is, I get them from the dealership.
Don't know the part number right off either.

NAPA has an o-ring that fits, can't remember the size, took a vacuum pump in to test fit.

Post by: fatmobile on February 19, 2010, 12:45:58 pm: Are you sure?
That doesn't add up.
10mm difference between inside diameter and outside,
but only 3mm thickness?

The base o-ring should be 36mm ID x 46mm OD x 3mm thickness.

tsk tsk tsk......... :D

Post by: 8v-of-fury on February 22, 2010, 11:16:33 am: Would just like to add, that I did the diaphragm-rotary pump swap. Swaps in, and brakes are better then any other mk1 ive driven.. gas or diesel
