hey,
I have a 1991 vw jetta diesel 1.6 non-turbo. It is leaking at the throttle shaft. I have spoken with a few specialists which gave me their advise.
I could have the top fixed in which 2 seals (1 push in seal/bushing) would be replced, or to rebuilt/replace the entire injection pump...
fixing the top is a lot cheaper, but does not guarantee that there are no leaks elsewhere...
anyone tackle either of these on their own... I
please help me out,
thank you,
robz
local bosch dealer can help you n getting the kit
get a Gile's pump and feel new power with out a turbo! will be just as fast !

You can fix the easy to get to seals yourself, but you're right, the pump will start leaking somewhere else not so easy to get to yourself.
The big problem is if you don't catch the next leak and it ends up getting diesel on the timing belt you'll be tossing your engine when/if the belt breaks.
Keep an eye on the belt if you don't have the whole pump rebuilt. If you don't absolutely know what you're doing, and can't afford to make a mistake putting the pump back together then I would recommend farming it out to someone who does.
Most likely the bushing insert is worn oblong and no seal will fix the leak. It's a straight-forward press out/press in job and the part runs about $25. Otherwise there's a typical O-ring on the throttle shaft and the molded seal that fits the shape of the pump cover - these 2 seals are included in the Bosch kit (both DGK 121 and 126, I believe), each kit can be had for $20 or less - shop around.
Getting the bushing will be the hard part, you need to know the ID, OD, length and dimensions of the step on the underside before calling your local friendly Bosch shop, then hope that they'll even sell you the individual parts. I had good luck with a shop in Fresno or somewhere in the "fertile valley" of California - I can probably dig up their info if you need.
It can get a little tricky to R&R the pump cover - how is your mechanical aptitude?
